Release Notes

We are pleased to announce the availability of version 4.10.5.0 (Navigate Edition) of the new HERE SDK for Flutter.

This is a stable release. We are constantly working on new features, stabilizing APIs, improving our KPIs, and evaluating your feedback.

Changes

This section documents major changes to this release that may require you to update your applications.

Version 4.10.5.0

New Features

Added MapMeasureRange class to hold a MapMeasure range, MapCameraLimits.zoomRange: MapMeasureRange property.
Added SdkContext.release() method. It is recommended to call this method once, when the application shuts down.
Added support for custom backends with the new EngineBaseURL enum and the customEngineBaseUrls field in SDKOptions.
Added MapCameraLimits.tiltRange(AngleRange) property.
Added support for Pedestrian routes and transport mode in OfflineRoutingEngine and for navigation.
Japan is now available as a separate offline maps Region download via MapDownloader. With enabled credentials, high-quality Japan map data can be downloaded. By default, only low-quality basic map data is available for download. Talk to your HERE representative to enable high-quality Japan map data. Note that this feature is already available since v4.10.4.0.
Route alternatives are now fully supported for electric vehicles. EV route alternatives are enabled when routeOptions.alternatives is in the range [1, 6]. Note that this feature is already available since v4.10.4.0.
Added MapCameraLimits.setBearingRangeAtZoom(MapMeasure, AngleRange), MapCameraLimits.clearBearingRanges, MapCameraLimits.setTiltRangeAtZoom(MapMeasure, AngleRange) and MapCameraLimits.clearTiltRanges.
Added MapCamera.cancelAnimations methods.
Added MapCameraListener interface, MapCamera.addListener(MapCameraListener), MapCamera.removeListener(MapCameraListener) and MapCamera.removeListeners methods.

Offline maps: When the same Region is downloaded multiple times, then multiple attempts to download the data are being made instead of answering with an error that a download for this Region is already in progress.

Version 4.10.2.0

New Features

Find traffic along a route: Added class TrafficIncidentOnRoute and read-only property Section.trafficIncidents. It represents traffic incidents on the route that are relevant for the section.
The RoutingEngine is now able to provide routes that contain altitude values along the route.
Added support for project scopes: With the new AndroidManifest meta-data option to specify a com.here.sdk.access_scope an app can set the HRN value as defined by your project ID. On iOS devices, use the plist key option to specify a Scope. Each app belongs to at least one or multiple projects. A possible use case can be to define a debugScope. See SDKOptions and the IAM Guide for more details.
Added isTruckLight flag to TruckSpecifications. It indicates that the truck can be classified as a car and that it is therefore excluded from legal restrictions (such as truck speed limits) for normal trucks when calculating the route. Note that specifications such as the physical dimensions, cargo, and others, are still taken into account.
Feature configurations can now be updated at the next application update. Added performFeatureUpdate method to MapUpdater class. Call this method once a feature configuration has been updated in AndroidManifest or plist file. As a result, the cached map data will be deleted and subsequently updated. Also, the downloaded regions will be updated to reflect the changes. Note that it is the developer's responsibility to decide when to perform the update. The HERE SDK does not decide or notify when such an update can be made. Calling performFeatureUpdate is only necessary once, after an application has been updated. Use feature configurations to limit the map data that is downloaded when panning and zooming the map view - or when downloading offline regions.

API Changes

Dropped support for Flutter 2.2.x. Flutter 2.5.0 and Dart 2.14.0 or newer are now required - as already announced for the last release.

Known Issues

Navigation: Outlines for MapPolyline lines can show a minimal gap at certain zoom levels. As a workaround use a round LineCap style.
The jamFactor indicating TrafficSpeed is currently calculated linear without taking road types and other parameters into account.
MapViewPin instances cannot be removed after tilting and panning the map.

Version 4.10.1.0

New Features

Routing: Route calculations can now be canceled via the returned TaskHandle when calling calculateRoute() or related methods on engines such as the RoutingEngine.
BYOD: Extended GeoPlace to hold more information: Added ExternalID, LocationDetails, WebDetails, BusinessDetails.
Added matchSideOfStreet property to Waypoint class. It specifies how the location set by sideOfStreetHint should be handled when reaching a destination.
Added value SUB_METER_NAVIGATION to LocationAccuracy enum. It causes HERE positioning to use high accuracy GNSS. Added values NOT_LICENSED and NOT_COMPATIBLE to LocationEngineStatus enum. They indicate additional error states related to HD GNSS. Added value HD_GNSS_POSITIONING to LocationFeature enum: It adds new supported feature to Positioning. Added value hdEnabled to SatellitePositioningOptions struct: If true, HD GNSS positioning is enabled.
Added global ParameterConfiguration that holds default values for HERE SDK features. For now, this allows to specify a walkingSpeedInMetersPerSecond to define a default pedestrian movement. Added TransitRouteOptions.fromDefaultParameterConfiguration() and PedestrianOptions.fromDefaultParameterConfiguration() that allow to create TransitRouteOptions and PedestrianOptions that will use the values set via ParameterConfiguration. The created options can then be used as usual for route calculation. Note that this is a beta feature.
Navigation: Added SpeedLimit.optimalWeatherSpeedLimitInMetersPerSecond property.
Added a new TrafficEngine that allows querying for current traffic incidents. Check the Traffic example app to see how it works. The TrafficEngine supports querying for traffic incidents in a bounding box, a circle, or a corridor. Querying for the exact traffic incident by ID. Traffic incidents can contain an incident type, an incident impact, an incident location (currently, a polyline with length), incident codes, an active time range, localized by the queried language description and summary, relevant vehicle restrictions, and more. It supports representations of traffic incident vehicle restrictions as a set of restricted vehicle properties of some vehicle category and filtering queried incidents by an incident type, an incident impact and an active time range.
Added RouteOptions.occupantsNumber: An option reflecting the number of occupants in a vehicle. Supported for car and truck transport modes. When it is higher than 1 it affects a vehicles ability to use HOV/carpool lanes. Defaults to 1.
Raised minimum supported Flutter version from 2.2.3 to 2.5.3. The latest Flutter version that is guaranteed to work is 2.8.1 - other versions may also work, but are not guaranteed to work.
Added support for truck speed limits and CVR (Commercial Vehicle Regulated) speed limits for SpeedLimitListener and SpeedWarningListener. Governmental regulations can specify an upper speed limit for certain vehicle types, such as trucks. If a local road sign indicates a speed limit of 130 km/h, then this can be overruled: In Germany, for example, the maximum allowed speed for trucks is 100 km/h. When navigation or tracking is started then the SpeedLimitListener and SpeedWarningListener will use the set TransportMode to notify on truck or car speed limits. As a result, a truck driver will receive on German highways never a speed limit notification that is higher than 100 km/h. Note that this feature is only available for map data >= 32 - as indicated by MapUpdater.getCurrentMapVersion().
Navigation: Added support for smooth location interpolation. This feature is already effective when using the VisualNavigator. Now it is also possible to get the calculated interpolated locations directly from the newly added InterpolatedLocationListener from a VisualNavigator instance. This allows for more customization options, for example, to smoothly animate map objects or new map view instances that show a different perspective than the main map view display.

API Changes

Changed type of RefreshRouteOptions constructor parameter from sdk.routing.TransportMode to sdk.transport.TransportMode.
Removed the previously deprecated release() method from all classes as it was doing nothing.
Removed the previously deprecated Maneuver.polyline. Use instead Section.polyline together with Maneuver.sectionIndex and Maneuver.offset.

Navigation: Deprecated the CameraSettings constructor that takes cameraDistanceInMeters, cameraTiltInDegrees, cameraBearingInDegrees. Please use the default constructor instead.

Resolved Issues

Navigation: Fixed an issue with truck vehicle restriction notifications.
Fixed: The newly introduced zoom level behaves inconsistent across different devices as the shown level of detail depends on the physical screen size of a device.
Fixed: Updating an existing MapMarker with a completely new image causes the marker to disappear for a brief moment before being drawn with the new image.
Fixed: Navigation: Maneuver voice notifications are sometimes triggered too early.
Fixed: When cachePath and persistentMapStoragePath are changed via SDKOptions, then it may not change the default path.
Fixed ManeuverNotifications for pedestrians: The timing when to trigger voice notifications is now adapted for pedestrians based on the set transport mode.
Fixed: Truck routes that are imported via importRoute() may be result in a RoutingError.NO_ROUTE_FOUND error as certain truck restrictions may be violated along the road. This is incorrect and instead the resulting route should contain the violated restrictions as part of the route's SectionNotice.
Fixed VisualNavigator that was showing two location indicators when a custom location indicator was set.

Known Issues

Navigation: Outlines for MapPolyline lines can show a minimal gap at certain zoom levels. As a workaround use a round LineCap style.
The jamFactor indicating TrafficSpeed is currently calculated linear without taking road types and other parameters into account.
MapViewPin instances cannot be removed after tilting and panning the map.
MapPolyline instances ignore alpha color settings and will appear fully opaque.
Transparency for MapPolylines is not supported.

An inner city Route for trucks carrying dangerous goods may not result in an error message.
RoutingEngine: The route import feature via a list of Locations cannot be used yet commercially and requires custom access credentials. Please contact your sales representative to get access.
Offline maps: When the same Region is downloaded multiple times, then multiple attempts to download the data are being made instead of answering with an error that a download for this Region is already in progress.

Version 4.10.0.0

New Features

Navigation: Added MilestoneStatusListener that informs if a milestone has been reached or missed. For this, check the newly introduced MilestoneStatus.
MapView: Added support for mercator projection when a MapView is created programmatically. Added HereMapOptions and MapProjection that allow to specify the map projection. Enhanced constructor of HereMap with optional options parameter of type HereMapOptions. Examples:
- HereMap(..., options: HereMapOptions(MapProjection.globe),)
- HereMap(..., options: HereMapOptions(MapProjection.webMercator),)
Added MapContext class and added getMapContext() method to HereMapController. A MapContext is needed when custom data sources for map tiles should be created, such as the new RasterDataSource to support custom raster layers on a MapView.
MapView: Added support custom raster layers that can be shown as tile overlay on top of the map. Note: This is a beta release of this feature, so there could be a few bugs and unexpected behaviors. Related APIs may change for new releases without a deprecation process. The following classes have been added to support custom raster layers:
- Added RasterDataSource which represents the source of raster tile data to display. It also allows changing its configuration.
- Added RasterDataSourceConfiguration which is used to specify a configuration for the data source, including URL, tiling scheme, storage levels and caching parameters.
- Added TilingScheme enum which specifies how the tile data has to be interpreted.
- Added RasterDataSourceListener interface which can be used to receive notifications from the RasterDataSource.
- Added MapLayer class which represents a renderable map overlay and controls its visibility.
- Added MapLayerBuilder which is used to create MapLayer objects.
- Added MapLayerPriority which specifies the order of drawing a map layer.
- Added MapLayerVisibilityRange which specifies at which zoom levels the map layer will become visible.
- Added MapContentType which specifies the type of data shown by the MapLayer.
Added support for feature configurations that allow to specify how much map data should be loaded when panning the MapView or when downloading a new Region for offline usage. For example, if a feature like turn-by-turn navigation is never used in an application, it can be removed. As a result, when panning the MapView less data will be downloaded into the cache. In addition, when downloading a new Region, its size will be smaller. By default, all features are enabled. However, if a "FeatureConfiguration" is present in the AndroidManifest and/or PList file, then only the listed features will be enabled, all others will be disabled. If you want to disable only one feature, then all other features need to be present, or they will be also disabled. For example, the following enables only navigation and truck features and disables all others on Android devices: <meta-data android:name="com.here.sdk.feature_configuration" android:value="NAVIGATION, TRUCK" /> and on iOS devices: <key>FeatureConfiguration</key><array><string>NAVIGATION</string><string>TRUCK</string></array>. As of now, these features can be specified:
1. "DETAIL_RENDERING": Additional rendering details like buildings. Only used for the MapView.
2. "NAVIGATION": Map data that is used for map matching during navigation. When not set, navigation may not work properly when being used offline.
3. "OFFLINE_SEARCH": Map data that is used to search. When not set, the OfflineSearchEngine may not work properly when being used offline.
4. "OFFLINE_ROUTING": Map data that is used to calculate routes. When not set, the OfflineRoutingEngine may not work properly when being used offline.
5. "TRUCK": Map data that is used to calculate truck routes. When not set, the OfflineRoutingEngine may not work properly when being used offline to calculate truck routes. It is also used for map matching during truck navigation. When not set, truck navigation may not work properly when being used offline.
The HERE SDK is now compatible with Dart FFI package versions >=1.0.0 <=1.1.2 - instead of just supporting FFI 1.0.
MapView: Added support for textured 3D landmarks. Enable 3D landmarks with the new MapScene.Layers.LANDMARKS constant like so: _hereMapController.mapScene.setLayerVisibility(MapSceneLayers.landmarks, VisibilityState.visible). Note that landmarks are only supported for newer map data >= 25, see mapUpdater.getCurrentMapVersion(). To ensure that 3D landmarks are visible, a map update may be required. Once a Region was updated, the map cache will be aligned automatically. Note that landmarks are released as beta.
Added HereMapControllerCore class. Added hereMapControllerCore property to HereMapController. HereMapControllerCore is used to initialize a MapLayer that can be used with a MapLayerBuilder to support custom raster layers.
Import routes: Added RouteHandle(String handle) constructor that allows to create a RouteHandle from a given string handle. Such a string can be provided from other backend sources such as HERE REST APIs and it is valid for a couple of hours. The string encodes a calculated route and it can be used to import this route via the newly added method importRouteFromHandle(RouteHandle routeHandle, RefreshRouteOptions refreshRouteOptions, CalculateRouteCallback callback) of the RoutingEngine for further use with the HERE SDK. Note: This is a beta release of this feature.
Search: Added a default constructor for Address.
Added support for BYOD (bring your own data) at runtime when searching for places. It's now possible to inject custom data for places that can be found with the OfflineSearchEngine. Such personal places can be found by regular queries. The results are ranked as other places coming directly from HERE. A new GeoPlace class was introduced that can contain custom place data. Multiple GeoPlace instances can be filled into a new data source called MyPlaces. This data source can be attached to the OfflineSearchEngine with its new attach() method. The added OnTaskCompleted event and TaskOutcome class are used to communicate the result of this asynchronous operation.
Added HERE positioning support for Android 12. If an application targets Android SDK version 31 or higher, users need to grant the device's "precise" location. When being prompted, it is not enough to select the "approximate" precision. Therefore, ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION permissions need to be present in a manifest file. HERE positioning needs the fine location permission in order to use GNSS and to make cellular and WiFi scans.
OfflineRoutingEngine: Maneuver.getExitSignTexts() is now supported when calculating routes offline.
Voice guidance: The ManeuverNotificationOptions have been extended with additional options and a ManeuverNotificationType to filter when voice texts are given:
- enableDestinationReachedNotification: A flag that indicates whether notifications for destination/stopover reached maneuvers should be generated.
- enableDoubleNotification: A flag that indicates whether double maneuver notification should be generated.
- enableHighwayExit: A flag that indicates whether highway exit information should be used when generating notifications.
- enablePhoneme: A flag that indicates whether phoneme for direction information should be used when generating notifications.
- enableRoundaboutNotification: A flag that indicates whether notifications for roundabout-related maneuvers should be generated.

API Changes

The lane assistance API is now stable and the beta status has been removed.
Deprecated MilestoneReachedListener, please use the newly introduced MilestoneStatusListener instead.
Removed the previously deprecated classes MapCamera.Orientation, MapCamera.OrientationUpdate, MapCamera.State.targetOrientation and all methods using them. Use instead the new methods that use the new classes GeoOrientation, GeoOrientationUpdate and MapCamera.State.orientationAtTarget. For example, instead of the removed method MapCamera.lookAtPointWithOrientationAndDistance(GeoCoordinates target, OrientationUpdate orientation, Double distanceInMeters) use now MapCamera.lookAtPointWithGeoOrientationAndDistance(GeoCoordinates target, GeoOrientationUpdate orientation, Double distanceInMeters).
Removed the previously deprecated GeoCorridor.radiusInMeters property. Use the new property GeoCorridor.halfWidthInMeters instead.
Removed the previously deprecated FarePrice.unit property. Use instead the FarePrice.validityPeriodInSeconds property.
Removed the previously deprecated method MapCamera.animateToAreaWithGeoOrientationAndViewRectangle(GeoBox target, GeoOrientationUpdate orientation, Rectangle2D viewRectangle, int durationInMs). Use one of the other available methods instead.
Removed the previously deprecated Agency.icon property. This feature is no longer supported.
Removed the previously deprecated map schemes: "preview.normal.day.json", "preview.normal.night.json", "preview.hybrid.day.json", "preview.hybrid.night.json". Use corresponding standard schemes instead: MapScheme.normalDay, MapScheme.normalNight, MapScheme.hybridDay, MapScheme.hybridNight.
Removed the previously deprecated LaneAssistanceListener. Use instead ManeuverViewLaneAssistanceListener.
Deprecated the method MapScene.setLayerState(String layerName, MapSceneLayerState newState). Use the new method MapScene.setLayerVisibility(String layerName, VisibilityState visibility) instead. Deprecated the enum MapSceneLayerState. Use the enum VisibilityState instead.

Resolved Issues

Voice guidance: Fixed errors for Hindi and Korean voice packages, which were causing missing notifications for some cases.
Fixed: During navigation, sometimes turn now maneuver notifications are provided too early.
Fixed LocationIndicator position on the screen when the MapView is tilted.
Routing: It is now possible to set a stop duration for each waypoint so that a better overal ETA can be given. Added 'durationInSeconds' property to Waypoint. It defaults to 0. Note that it will be ignored for pass-through waypoints.
Fixed: MapViewLifecycleListener.onAttach() is now called once MapView has been fully initialized.
LocationSimulatorOptions.notificationIntervalInMilliseconds: Fixed issues with too short notification intervals. Values less than 1 ms are clamped to 1 ms to guarantee normal location updates during guidance simulation.
Fixed: HERE Positioning / LocationEngine does not work yet with Android 12.
Fixed: During navigation, the number of sections within RouteProgress may not match the number of sections within the Route. A new MilestoneStatusListener has been added that informs if a milestone has been reached or missed.

Known Issues

Updating an existing MapMarker with a completely new image causes the marker to disappear for a brief moment before being drawn with the new image.
The newly introduced zoom level behaves inconsistent across different devices as the shown level of detail depends on the physical screen size of a device.
Transparency for MapPolylines is not supported.
Flutter's hot restart feature does not work when the map is moved. This results in an application freeze.
MapViewPin instances cannot be removed after tilting and panning the map.
The jamFactor indicating TrafficSpeed is currently calculated linear without taking road types and other parameters into account.
An inner city Route for trucks carrying dangerous goods may not result in an error message.
Navigation: Maneuver voice notifications are sometimes triggered too early.
Outlines for MapPolyine lines can show a minimal gap at certain zoom levels. As a workaround use a round LineCap style.
Truck routes that are imported via importRoute() may be result in a RoutingError.NoRouteFound error as certain truck restrictions may be violated along the road. This is incorrect and instead the resulting route should contain the violated restrictions as part of the route's SectionNotice.
Offline maps: When the same Region is downloaded multiple times, then multiple attempts to download the data are being made instead of answering with an error that a download for this Region is already in progress.
When cachePath and persistentMapStoragePath are changed via SDKOptions, then it may not change the default path.

Version 4.9.4.0

New Features

Routing: Introduced Departure and Arrival time for each Section of a Route.
Routing: Added support for bicycles. Now it is possible to create bicycle routes online with the RoutingEngine using BicycleOptions. Added also TransportMode.bicycle.
Increased the supported maximum Flutter version from 2.5.2 to 2.5.3. The maximum supported Dart version was updated from 2.14.3 to 2.14.4. Newer versions may also work, but are not guaranteed to work.
Routing: Added optional field nameHint to Waypoint. For cases when there are multiple places at the same geographic coordinate, this hint can help the RoutingEngine to find the expected place. For example, "North" can be set to differentiate between interstates "I66 North" and "I66 South".
Routing: It's now possible to set TaxiOptions.allowDriveThroughTaxiRoads. It allows to calculate routes that make use of roads and lanes that are reserved for taxis.
Bicycle routes are now also supported for turn-by-turn navigation and tracking.

Resolved Issues

Fixed: In rare cases, the map view can show a gray screen right after start-up and the application may appear not responding (ANR).

New Features

OfflineRoutingEngine: Added support for notice spans - as already known from the online RoutingEngine.
Added new map layer with MapScene.Layers.safetyCameras to show safety camera icons on the map.
The visibility of embedded carto POIs on the map can now be controlled with the new static method MapScene.setPoiVisibility(List<String> categoryIds, VisibilityState visibility) to set a VisibilityState for a list of POI categories.

API Changes

Renamed the class PickMapFeaturesResultPickPoiResult to PickPoiResult.

Resolved Issues

OfflineRoutingEngine: For truck routes now a SectionNotice with violated restrictions is provided instead of a route calculation resulting in a RoutingError.
Navigation: Improved tunnel extrapolation during tracking mode.
Fixed: Picking map features such as embedded POIs and map items via mapView.pickMapItems and mapView.pickMapFeatures is currently not possible at the same time.

Version 4.9.2.0

Highlights

Removed the beta status for the HERE SDK for Flutter. Please note, that due to the rapid development of Dart and Flutter also our HERE SDK APIs may change for new releases without prior notice or a deprecation process. We expect that this will happen only for rare exceptional cases - if at all. From now on, for the majority of cases the HERE SDK for Flutter will follow a deprecation process and upcoming breaking changes will be communicated via Release Notes and in the API Reference documentation.
Added iOS simulator support for M1 machines with a new ios-arm64_x86_64-simulator framework that is included now in the XCFramework along with the ios-arm64 framework. Now it is possible to start simulators without any workaround on M1 machines. Note that bitcode optimization is only enabled for ios-arm64.

New Features

Added LocationIndicator.updateLocation(Location location, MapCameraUpdate cameraUpdate) to update the location of the indicator and the target coordinates of the MapView at the same time - for example, when tracking the user's location.
Offline Routing: Enabled a property for RouteOptions that allows to set an upper limit of the driving speed of a vehicle: speedCapInMetersPerSecond is available for car and truck transport modes. It can affect route path and ETA. Note that this property was already available for online routing.
Added a feature to observe when a MapCamera animation or flyTo()-call has been completed: Added AnimationListener interface, 'AnimationState' enumeration, MapCamera.startAnimationWithListener method, MapCamera.flyToWithOptionsAndGeoOrientationAndListener and MapCamera.fflyToWithOptionsAndGeoOrientationAndDistanceAndListener methods.
Added a feature to pick embedded carto POIs. By default, embedded POIs are visible on the map and they can be picked now via mapView.pickMapFeatures() to get a PickMapFeaturesResult that contains a PoiResult. Check the Developer's Guide for a usage example.
Added a convenience feature to tie a LocationIndicator directly to the MapView's life cycle'. For example, be calling the new enable() method, the LocationIndicator is visible on the map. This has the same affect as when calling mapView.addLifecycleDelegate(locationIndicator). Added factory method LocationIndicator.withMapView(MapViewBase mapView), added methods LocationIndicator.enable(MapViewBase mapView), LocationIndicator.disable().
MapMarkerCluster items can now be picked - and when picking other map items, clustered markers are no longer returned via pickMapItemsResult.getMarkers(). Instead, call the new pickMapItemsResult.getClusteredMarkers() method. See the MapItems example app and the Developer's Guide for a usage example.

Resolved Issues

VisualNavigator: Fixed out of sync maneuver arrows after a route recalculation.
Fixed: Depending on your configuration when running on Xcode simulator, you may need to modify the post_install task in the generated Podfile. Now, arm64 M1 support is already integrated by default.

New Features

Offline routing: Added PreActions and PostActions handling related to a time needed to board/disembark a ferry.
Added removeMapMarkers() method to MapScene class. It removes multiple map markers in a batch call.

API Changes

Removed deprecated tag for persistentMapStorageFolderAccessDenied. persistentMapStorageFolderAccessDenied is not deprecated anymore.
Deprecated MapCamera.animateToAreaWithGeoOrientationAndViewRectangle(GeoBox target, GeoOrientationUpdate orientation, Rectangle2D viewRectangle, int durationInMs). Use one of the other available methods instead.
Deprecated MapCameraFlyToOptions.durationInMs, use MapCameraFlyToOptions.duration instead.

Resolved Issues

Fixed: Route imports no longer fail when Location.time is set.
Navigation: Fixed location jumps after leaving tunnels.
ReturnToRoute: Fixed rerouting during navigation. It considers now the original RouteOptions.
Offline routing: Fixed missing country code value for Maneuver class.
Fixed: VisualNavigator now restores/removes map items when attaching or detaching a mapview.
Fixed navigation issues when obsolete GPS locations where being queued and processed after new locations were already available.
Fixed: Navigation now prefers the optional Location.time when set.
Fixed: VisualNavigator now updates MapView based on events sent by MapViewLifecycleListener. This prevents that tracking is stopped after coming back to foreground.

The latest stable Flutter version that works with the HERE SDK was updated from 2.2.2 to 2.2.3. Newer versions may also work, but are not guaranteed to work.

New Features

Public transit routes: Added support for new pedestrian sections to provide better information on in-station walks, for example, when walking from a place of type accessPoint type to a place of type station.
Routing: Added RouteOptions.enableTrafficOptimization property which is true by default, and when set to false, it doesn't consider traffic information and ignores RouteOptions.departureTime.
Routing: It's now possible to avoid individual segments on a Route. With the newly added segments field in AvoidanceOptions users can specify the parts of a route they would like to avoid after a recalculation. The segments can be identified via Route -> Section -> Span -> SegmentReference.
- Added SegmentReference class that represents a reference to a segment id with a travel direction.
- Added getSegmentReference method to the Span class.
- Added TravelDirection enum that indicates the travel direction along a segment.
Offline routing: When using OfflineRoutingEngine.returnToRoute() the new route contain now the initial RouteHandle.

Routing: Added violatedAvoidSeasonalClosure, violatedAvoidTollTransponder, seasonalClosure, tollTransponder, tollsDataUnavailable and chargingStopNotNeeded symbols to the SectionNoticeCode enum.
Navigation: Voice guidance now supports four additional regional languages in India: Bengali, Kannada, Malayalam, and Telugu.

API Changes

Transit routes no longer provide fare information and the TransitSectionDetails.fares list is always empty.
Routing: Deprecated SectionNoticeCode.violatedPedestrianOption symbol. It will be removed in v4.11.0 as it is no longer supported.
Deprecated persistentMapStorageFolderAccessDenied and failedToLockPersistentMapStorageFolder values from the InstantiationErrorCode enum. The persistent storage directory is no longer locked.

Resolved Issues

Fixed: Missing language support for no-NB and pt-BR for distant maneuver notifications.
Fixed: It is not possible to set both RouteOptions.departureTime and RouteOptions.arrivalTime at the same time. Plus, RouteOptions.arrivalTime is ignored when RouteOptions.enableTrafficOptimization is set to false.

Version 4.8.2.0

New Features

Improved search for electric vehicle charging stations: Added classes EVChargingPool and EVChargingStation. A charging pool for electric vehicles is an area equipped with one or more charging stations. A charging station defines a group of connectors for electrical vehicles that share a common charging connector type and max power level. Note: This is a beta feature.
Navigation: Improved TruckRestrictionWarning and SafetyCameraWarning events. With the new WarningType you can now get notified if the location of the truck restriction or the safety camera lies ahead or if it was just passed by.
Improved search for electric vehicle charging stations: Added property Details.evChargingPool that represents the details of the charging pool for electric vehicles. Note: This is a beta feature.
Routing: Added information on toll costs with a new PaymentMethod enum, TollFare & Toll structs and Section.tolls property. Note: This is a beta feature.

API Changes

Deprecated DynamicRoutingListener which is replaced by the newly introduced DynamicRoutingEngineListener. The listener is now set with the new DynamicRoutingEngine.start(route, listener) method which can throw a StartException if no RouteHandle was requested for the route. Route calculation errors are propagated via the newly added DynamicRoutingListener.onRoutingError(). Check the navigation_app app for a usage example.

Resolved Issues

ReturnToRoute: Fixed rare cases that could lead to a crash or invalid maneuvers when the feature was used offline.
Corrected the Hindi translation for "yards".
Navigation: Corrected the Greek translation of the "turn sharp" maneuver notification.
ReturnToRoute during navigation: Fixed possible negative values for maneuver lengths and removed maneuvers with no geometry for cases when returnToRoute was called multiple times. As a benefit, now a longer part of the original route can be preserved.
Fixed: In rare cases, Storage.LevelDB related crashes can occur when starting the app.
Fixed: Voice navigation: The voice announcements for multiple speed cameras that are very close to each other are delivered for both cameras at the same time, so that the first event may be skipped.
Fixed: Navigation: When using JunctionViewLaneAssistance for very long routes then a significant delay can occur before navigation is actually started. Currently, this happens because the entire route is traversed beforehand.

Version 4.8.1.0

New Features

Offline Maps: Extended the MapDownloader to check for broken maps with getInitialPersistentMapStatus(). Added also repairPersistentMap(), so that broken maps can be repaired asynchronously. Check the Developer's Guide or the OfflineMaps example app for a usage example.
Routing: Added NoRouteHandle enum value to RoutingError to indicate that the route did not contain the required RouteHandle, which is needed, for example, to refresh a route.
Search: Added new name property to PlaceCategory that provides a level 3 description.

API Changes

Renamed GeoCorridor.make() to GeoCorridor().
Renamed Navigator.make() to Navigator().
Renamed VenueEngine.make() to VenueEngine().

Known Issues

Updating an existing MapMarker with a completely new image causes the marker to disappear for a brief moment before being drawn with the new image.
The newly introduced zoom level behaves inconsistent across different devices as the shown level of detail depends on the physical screen size of a device.
Map caching may not work as expected for satellite map scheme. Existing tiles may be reloaded.
Transparency for MapPolylines is not supported.
Flutter's hot restart feature does not work when the map is moved. This results in an application freeze.
MapViewPin instances cannot be removed after tilting and panning the map.
The jamFactor indicating TrafficSpeed is currently calculated linear without taking road types and other parameters into account.
An inner city Route for trucks carrying dangerous goods may not result in an error message.
Offline routing: For RouteOptions: AvoidanceOptions.countries are currently ignored.
Leaving an app via back press on Android devices can lead to a freeze when the app is restarted. This can happen when the LocationEngine could not be properly stopped or the VisualNavigator is still rendering.
MapUpdater: After initial download of a region a newer version is already available for download.
In rare cases, Storage.LevelDB related crashes can occur when starting the app.
In rare cases, the map view can show a gray screen right after start-up and the application may appear not responding (ANR).
Voice navigation: The voice announcements for multiple speed cameras that are very close to each other are delivered for both cameras at the same time, so that the first event may be skipped.
During navigation, the number of sections within RouteProgress may not match the number of sections within the Route. In rare cases, this can lead to missed milestone reached events.
Navigation: When using JunctionViewLaneAssistance for very long routes then a significant delay can occur before navigation is actually started. Currently, this happens because the entire route is traversed beforehand.

Version 4.8.0.0

Highlights

The minimum supported Flutter and Dart version was raised to Flutter 2.0 and Dart 2.12.
FFI 1.0 is now supported, which means that other 3rd party plugins also need to be updated to use FFI 1.0, or they can't be used together with the HERE SDK.
Support for null safety was added. Null safety can be optionally disabled.
It's no longer necessary to call release() to dispose an object. The method has been deprecated and it will be removed in the future. When still calling it, it will do nothing.
A new reference application for the HERE SDK for Flutter (Navigate Edition) was published on GitHub. It shows how a complex and release-ready project targeting iOS and Android devices may look like. You can use it as a source of inspiration for your own HERE SDK based projects - in parts or as a whole. Many parts of the app overlap with the Explore Edition - however, guidance requires the Navigate Edition. At the moment, only HERE SDK 4.7 is supported.

New Features

Truck navigation: Added a listener for TruckRestrictionWarning to the Navigator and VisualNavigator, which is called at a specific distance while navigating along a route in order to warn about a truck restrictions ahead. It can contain multiple truck restrictions. For now, the following restrictions are possible: WeightRestriction and DimensionRestriction. Check the Navigation example app for an usage example.
Lane assistance: Added a JunctionViewLaneAssistance listener to Navigator and VisualNavigator that informs on the possible lanes and complex junctions.

Version 4.7.7.0

Highlights

Preview: Flutter version and FFI version have been raised. Support for null safety was introduced. It's no longer necessary to call release(). The HERE SDK reference application was introduced on GitHub. See the details for all these changes in the highlights for the 4.8.0.0 release above.

New Features

Search: Added politicalView member to Place class. The optional value can be checked if it is matching the one that was set beforehand via SDKOptions.
MapUpdater: The current map version of a downloadable region is now exposed. This can be useful for debugging potential map data issues.
Added a new DynamicRoutingEngine that allows to periodically request traffic-optimized routes. This can be useful to notify users on better routes while staying in a route planner or during a guidance context when the traffic situation has changed.

API Changes

The map styles for NORMAL_DAY, NORMAL_NIGHT, HYBRID_DAY and HYBRID_NIGHT have been updated to the ones that have been made available as preview beforehand. The new map styles feature a clean and neutral base map and a street network with improved gray scales that allow a better hierarchy of elements that can be added on top.
MapView: "Simplified Chinese", "Traditional Taiwan" and "Traditional Hong Kong" language labels are now supported.
Removed the "fromLambda" constructor from all related Dart classes, for example Gestures, MapDownloader, SearchEngine and so on. Instead of creating a gesture listener like this: tapListener = TapListener.fromLambdas(lambda_onTap: (Point2D p) { ... }); the code can be simplified now to: tapListener = TapListener((Point2D p) { ... });.
Routing: Updated the API for the returnToRoute and refreshRoute features for RoutingEngine and OfflineRoutingEngine:
- Changed the parameter order of RoutingInterface.returnToRoute(): The startingPoint parameter is now the second parameter, not the third parameter. The feature is still in beta.
- Added a startingPoint parameter to the RoutingEngine.refreshRoute() method. In return, deleted RefreshRouteOptions.updateStartingPoint(). The feature is still in beta.
- Deleted the ReturnToRouteEngine. Use the newly introduced RoutingInterface.returnToRoute() method instead.

Resolved Issues

Fixed: A Maneuver.polyline list of GeoCoordinates has only one element for the last maneuver of a route.
Fixed: When MapMarker.setOverlapAllowed() is set to false and the map is zoomed, this can lead to a flickering of the marker assets.
Fixed: Navigation: In some cases, speed limit data may be missing, although it is available in HERE's database.
VisualNavigator: An issue was fixed, where in a rare conditions map matched positions are temporarily missing between interpolations causing the map to rotate to a wrong direction or to not rotate at all.
The VisualNavigator now renders correctly, even if the principal point of the map view was changed by an application.
Fixed: Leaving an app via back press on Android devices can lead to a freeze when the app is restarted. This can happen when the LocationEngine could not be properly stopped or the VisualNavigator is still rendering.

Version 4.7.6.0

Highlights

Important note: It is planned to raise the minimum supported Flutter and Dart version to Flutter 2.0 and Dart 2.12 with the upcoming major release v4.8.0. With this release we also plan to switch to FFI 1.0, which means that other 3rd party plugins also need to be updated to use FFI 1.0, or they can't be used together with the HERE SDK. In addition, we plan to introduce null safety. Note that the HERE SDK is not compatible with Flutter 2.2.0 or higher - as the HERE SDK does not yet support FFI 1.0 until v4.8.0.

New Features

Offline maps: Added MapUpdater class that allows to update previously downloaded regions. It also allows to check if one or more updates are available. A usage example can be seen in the OfflineMaps example app.
Improved map rendering performance on low end devices.
Navigation: Added support for Serbian voice maneuver notifications during guidance.

Resolved Issues

Fixed: Offline maps: Some downloadable region names are not fully localized yet.
Fixed: Offline routing: Offline routes cannot be calculated in Japan.
Offline Maps: A retryable error is not returned via MapDownloader.onPause(), instead the download is stopped and must be restarted instead of resumed.

Version 4.7.5.0

Highlights

Important note: It is planned to raise the minimum supported Flutter and Dart version to Flutter 2.0 and Dart 2.12 with the upcoming major release v4.8.0.

In addition, we plan to introduce null safety. Note that the HERE SDK is not compatible with Flutter 2.2.0 or higher - as the HERE SDK does not yet support FFI 1.0 until v4.8.0.

New Features

Routing: Added avoidance options for pedestrians with PedestrianOptions.avoidanceOptions.
Search: Added support to search along longer route polylines with a GeoCorridor. Either increase halfWidthInMeters when set via constructor or do not set it - by using the GeoCorridor constructor that only allows to set the GeoPolyline. The parameter radiusInMeters has been deprecated: Please only use halfWidthInMeters as constructor parameter to specify the thickness of the route corridor. When increasing halfWidthInMeters then a greater simplification of the polyline shape can be achieved resulting in a longer route that can be searched along. On the downside the results are less accurate and can lie farther away from the route. When halfWidthInMeters is not set, a suitable value is set internally based on "best guess".
The LocationIndicator now supports a gray state that can be set via LocationIndicator.isActive.
Navigation: Added support for Vietnamese voice maneuver notifications during guidance.
Navigation: Added a RoadAttributesListener that informs on the following new road attributes: isDirtRoad, isTunnel, isBridge, isRamp, isControlledAccess, isPrivate, isNoThrough, isTollway, isDividedRoad, isRightDrivingSide, isRoundabout.
Offline routing now also supports AvoidanceOptions for rectangular areas.
Offline maps: Added more granular error states to MapLoaderError.

Resolved Issues

VisualNavigator: The camera now moves instantly to the initial location when the first Location update is received.

New Features

Routing: Added TruckType enum to specify the type of a truck for the TruckSpecifications.
Routing: Added TruckSpecifications.trailerCount to specify the number of trailers.
Routing: Added accessPoint to RoutePlaceType enum. It allows to differentiate Section's based on RoutePlace.type.
Public transit: Added FarePriceType enum, FarePrice.type, FarePrice.minimum and FarePrice.maximum properties. FarePrice provides the actual price value.

API Changes

Gestures: A finger down gesture stops now any ongoing animation including kinetic panning.
Positioning: Background location updates are no longer enabled by default. They need to be enabled via LocationEngineBase.setBackgroundLocationAllowed(). On top, the device needs to require the needed permissions.
Changed the VisualNavigator.make() constructor to VisualNavigator().
Offline maps: Added ALREADY_INSTALLED enum value to MapLoaderError. Now, downloading an existing map region will result in ALREADY_INSTALLED error instead of getting a SUCCESS.
Routing: Deprecated FarePrice.unit, use the newly introduced FarePrice.validityPeriodInSeconds property instead.
Routing: Deprecated the unsupported Agency.icon property. This property is no longer supported and will be removed with HERE SDK release v4.10.0.

New Features

Routing: Added support for EVCarOptions and EVTruckOptions for the RefreshRouteOptions class.
EV Routing: Added new parameters to BatterySpecifications:
- minChargeAtChargingStationInKilowattHours: The minimum charge when arriving at a charging station.
- minChargeAtDestinationInKilowattHours: The minimum charge at the final route destination.
- maxChargingVoltageInVolts: The maximum charging voltage supported by the vehicle's battery.
- maxChargingCurrentInAmperes: The maximum charging current supported by the vehicle's battery.
- chargingSetupDurationInSeconds: The time spent after arriving at a charging station, but before actually charging.
SearchEngine: For reverse geocoding it is now possible to search in a GeoCircle with searchByCoordinatesWithRadius(GeoCircle circle, SearchOptions options, SearchCallback callback).

API Changes

Only the following Android Gradle Plugin versions 3.3.3, 3.4.2, 3.5.4, 3.6.4, 4.0.1 or higher are supported - since internally the tag is required for the internal AndroidManifest file used by the HERE SDK. In case of doubt, you can check the version in your_app/android/build.gradle and check the version set for com.android.tools.build:gradle. Newer projects created by your IDE of choice already use such a version, by default.

API Changes

Navigation: Deprecated the LaneAssistance class and the related Navigator.laneAssistanceListener property. Use the newly introduced ManeuverViewLaneAssistance class and the Navigator.maneuverViewLaneAssistanceListener instead.

Resolved Issues

Fixed: Offline routing - RouteOptions are currently ignored completely and only default values will be used.
Fixed: ReturnToRouteEngine: The guidance maneuver at the merging point between the new route and the old route is not properly generated.

Version 4.7.2.0

Highlights

Important note: It is planned to raise the minimum supported Flutter and Dart version to Flutter 2.0 and Dart 2.12 with the upcoming major release v4.8.0. With this release we also plan to switch to FFI 1.0, which means that other 3rd party plugins also need to be updated to use FFI 1.0, or they can't be used together with the HERE SDK. In addition, we plan to introduce null safety.
The Developer's Guide has been extended and is now on par with the content that was already available for the native platforms.

New Features

Added a feature to refresh a Route: Added the RouteOptions.enableRouteHandle flag to get a RouteHandle, a RefreshRouteOptions class and a RoutingEngine.refreshRoute() method. Note that currently EVRouteOptions are not supported. See the related chapter in the Developer's Guide for more information.
LocationIndicator: Added a new style for pedestrians. The new style is added to IndicatorStyle and can be set to a LocationIndicator instance to switch the default 3D map marker model to indicate the current heading and location. Optionally, the style can be customized.
Added an option to affect FPS rendering of the map view by decreasing or increasing the frameRate with MapView.frameRate. This can be useful to reduce CPU usage for low end devices. The default FPS is 60 frames per second. It is also possible to deactivate automatic render cycles by setting FPS to 0.
Offline maps: Added MapDownloader.clearPersistentMapStorage() to clear the persistent storage to remove all downloaded map data.
Simplified usage of special speed limits: Now the lowest current special speed limit is optionally exposed via effectiveSpeedLimitInMetersPerSecond(). It's no longer necessary to set a Date(), the HERE SDK handles this now internally based on the device's clock settings. The related APIs (TimeDomain, SpecialSpeedSituationType, SpecialSpeedSituation) have been deprecated. Added the following new fields to the SpeedLimit class:
- double advisorySpeedLimitInMetersPerSecond
- double snowSpeedLimitInMetersPerSecond
- double rainSpeedLimitInMetersPerSecond
- double fogSpeedLimitInMetersPerSecond
- double schoolZoneSpeedLimitInMetersPerSecond
- double timeDependentSpeedLimitInMetersPerSecond

API Changes

MapDownloader: Added new pause / resume events to DownloadRegionsStatusListener to know when a download of a region or a list of regions was paused or resumed. Introduced these two new methods: onPause(MapLoaderError error) and void onResume(). The error is populated when the download was paused by the MapDownloader due to a retryable error.
VisualNavigator rendering is, by default, smooth again with a target frame rate set to 60 FPS. This can be adjusted for low end devices. See the frameRate setting for MapView.

Resolved Issues

Fixed: MapMarker3D instances are only partly rendered when the camera is positioned too far from earth.
Fixed: Offline maps: Once any download for a Region fails or is cancelled, all already downloaded regions will be deleted as well.

Known Issues

The VisualNavigator API is in an early development stage. More features and overall stabilization are planned for the next releases. Because of the pandemic situation full test coverage is currently blocked.
Updating an existing MapMarker with a completely new image causes the marker to disappear for a brief moment before being drawn with the new image.

Version 4.7.1.0

Highlights

Added a default 3D LocationIndicator to show the current location and travel direction of a user. It can be added to the map view with MapView.addMapLifecycleListener(). Update its location via Mapview.updateLocation() that accepts a Location as parameter. The look of the default asset can be customized by setting a MapMarker3DModel as parameter to LocationIndicator.setMarker3dModel(). You can also specify the MarkerType: In the future, it may be used to enable different styles of markers for different use cases.
Introduced customizable visual navigation. Added CameraSettings that can be set for VisualNavigator. You can specify cameraDistanceInMeters to define the distance to earth, the cameraTiltInDegrees to specify the 3D effect (a value of 0 switches to a flat 2D view) and cameraBearingInDegrees which can be set to null to rotate the map into the travel direction (any other value will stop the rotation - for example, set it to 0 to enable north up mode). By default, rotations are enabled.

New Features

Introduced taxi routes. Added TransportMode.taxi type and a TaxiOptions class to calculate routes optimized for taxis via RoutingEngine.calculateTaxiRoute(). Note: This is a beta release of this transport mode, so there could be a few bugs and unexpected behaviors.
Routing: Added RouteOptions.speedCapInMetersPerSecond to limit the maximum allowed speed for a vehicle. When set, the route duration will be shorter for car and truck transport modes. For scooter routes it may also affect the route geometry. Other transport modes are ignored.

API Changes

Changed type of screenshot object returned by HereMapController.takeScreenshot() from an Image object to a ImageInfo object. Flutter's Image is actually of type Widget, which makes it more difficult to access the RGB data. Dart's ImageInfo simplifies this and it can still be converted to a Flutter Widget, if desired.

Resolved Issues

Fixed: Public transit routes do not contain maneuvers.
Fixed: On iOS devices, MapViewPin instances disappear from MapView when changing device orientation. They reappear when moving the map.
Fixed: Starting LocationEngine on iOS devices fails when the device is in flight mode.
Fixed: Offline maps: The new method to get installed regions may result in an error. As a workaround get available map regions beforehand and try again.

Highlights

Raised the minimum supported Flutter version from Flutter 1.20 to Flutter 1.22 and Dart 2.10. It is planned to raise the minimum supported Flutter and Dart version to Flutter 2.0 and Dart 2.12 with the upcoming major release v4.8.0.
New Flutter example apps added on GitHub: The Flutter selection contains now the same set of example apps as the native iOS and Android platforms.
Introduced public transit routing with a new TransitRoutingEngine that can calculate public transit routes. It uses TransitWaypoint type waypoints and a TransitRouteOptions class to specify various transit related options. Note that the API is in an early development stage. More features and overall stabilization are planned for the next releases.
Added a new MapSceneLayers.vehicleRestrictions layer. It can be activated with MapScene.setLayerState() and it shows the current vehicle restrictions on the map. For example, weight or height restrictions for trucks at bridges.

New Features

Along with the newly introduced TransitRoutingEngine (see above), the following supportive types have been added: AttributionType enum, FarePriceType enum, FareReason enum, PreActionType enum, TransitDepartureStatus enum, TransitIncidentType enum, TransitIncidentEffect enum, TransitMode enum, TransitModeFilter enum, Agency class, Attribution class, Fare class, FarePrice class, PreAction class, TransitIncident class, TransitDeparture class, TransitSectionDetails class, TransitStop class, and TransitTransport class.
Routing: Introduced a new Span class that is accessible from a Section on a Route. It points to the related section notices to indicate possible route violations. With the Span class these violations can now be identified on the Route as they contain the length in meters and the geometry.
Routing: Added additional constructor for IsolineOptions.Calculation: IsolineOptionsCalculation.withDefaultsAndCalculationMod(IsolineRangeType rangeType, List<int> rangeValues, IsolineCalculationMode isolineCalculationMode).
Search: Added new method to SearchEngine to get place details for a Suggestion that contains a href String. Use the new sendRequest() method for this.

API Changes

Added a new MapViewLifecycleListener that replaces the deprecated MapRepresentable. It can be added or removed from a Mapview. Use this to get notified on the map view's lifecycle.
Deprecated MapRepresentable and the related methods to add or remove it from a MapView. Use the newly introduced MapViewLifecycleListener instead.
Removed the previously deprecated GeoBox.intersects(GeoBox) and GeoBox.contains(GeoBox).
Speed limits: Made SpecialSpeedSituation.specialSpeedLimitInMetersPerSecond non-optional and removed the enum items speedBumpsPresent and laneDependent from SpecialSpeedSituationType, because they do not contain a special speed limit.
Added a new RoadTextsListener to get notified on the current road name.
Deprecated NavigableLocation.streetName. Use the newly introduced RoadTextsListener instead.
Removed the previously deprecated UnitSystem.imperial enum item.
Removed the previously deprecated LocationProvider and the LocationListener.onLocationTimeout() method.

Version 4.6.5.0

New Features

Added support for political views. SDKOptions allow now to specify the politicalView string. It's a three letter country code defined by ISO 3166-1 alpha-3. When set, all map data will respect the point of view of this country. Note that this is a beta feature and thus there can be bugs and unexpected behaviour.
A Place can now be serialized or deserialized with serializeCompact() and deserialize() to or from a String.
Routing: Added SectionNoticeCode and NoticeSeverity enums, SectionNotice class and Section.sectionNotices property to get informed on possible route violations.
Isoline Routing:
- Added RoutePlaceDirection enum with values arrival and departure.

- Extended the existing IsolineOptions.Calculation constructor to accept the new RoutePlaceDirection enum.
- Added RouteOptions.arrivalTime to set an optional time when a travel is expected to end. Note that this parameter is currently only supported for isoline route calculation.
Navigation: Added an API to notify users about changes of the current speed limit. Now a SpeedLimitListener can be set that allows to get the SpeedLimit as before, but optionally it may also contain information on SpecialSpeedSituation events that overrule the default speed limit. Reasons for this are defined in the SpecialSpeedSituationType enum. A TimeDomain value informs whether this speed limit is currently active or not.
Navigation: Added a new ReturnToRouteEngine that allows the calculate a new route when a deviation from the original route was detected. This engine works offline on already downloaded or cached map data.
Introduced new SDKCache class and SDKCacheCallback that allows to clear the temporarily downloaded map data via the new clearCache() method. Note: This will not delete downloaded offline maps data.
Offline Search: Added new OfflineSearchEngine.search() method that accepts PlaceIdQuery and an optional LanguageCode to lookup a Place ID.

API Changes

Routing: Deprecated the Notice class and NoticeCode enum along with Section.notices property, use the newly introduced SectionNoticeCode, SectionNotice class and Section.sectionNotices property instead.

New Features

Offline maps: It's now possible to pause and resume pending downloads of a map region via the MapDownloaderTask's pause() and resume() methods.
Navigation: Maneuver arrows are now rendered by default on the route shown on the map by the VisualNavigator. The next maneuver is shown, and removed once reached.
Navigation: The turn-by-turn ManeuverAction for roundabouts is now split into 'roundaboutEnter' and 'roundaboutExit'. The behavior for the HERE SDK remains the same. An additional 'LEFT/RIGHT_TURN' action may be given when exiting a larger roundabout.
Routing: Introduced Waypoint.minCourseDistanceInMeters to specify an optional distance parameter during which a user can avoid taking actions.
The size of the viewport can now be retrieved from MapView with the new viewportSize property that returns Size2D in physical pixels.
Enhanced FlyTo MapCamera animations from A to B with target orientation and target distance: flyToWithOptionsAndOrientation(GeoCoordinates target, MapCameraOrientationUpdate orientation, MapCameraFlyToOptions animationOptions).
New map styles have been introduced as beta versions.
- The map styles for normalDay, normalNight, hybridDay and hybridNight will be updated with v4.8.0. The planned new map styles are already accessible under following file names as beta versions:
  - "preview.normal.day.json" - This scheme will update the current normalDay in v4.8.0.
  - "preview.normal.night.json" - This scheme will update the current normalNight in v4.8.0.
  - "preview.hybrid.day.json" - This scheme will update the current hybridDay in v4.8.0.
  - "preview.hybrid.night.json" - This scheme will update the current hybridNight in v4.8.0.
- The legacy map styles for normalDay, normalNight, hybridDay and hybridNight will still be accessible for v4.8.0 until v4.9.0 under the file names listed below. They will be removed with v4.9.0.
  - "legacy.normal.day.json"
  - "legacy.normal.night.json"
  - "legacy.hybrid.day.json"
  - "legacy.hybrid.night.json"
  - "legacy.grey.day.json"
  - "legacy.grey.night.jso

API Changes

The map styles MapScheme.greyDay, MapScheme.greyNight have been deprecated and will be removed. Use the normal variants instead.
Navigation: Safety speed camera warner text notifications were always fired. Now, text notifications are only sent via ManeuverNotificationListener if a SafetyCameraWarningListener is set.

Resolved Issues

For Android: The workaround required to avoid a white screen being displayed after sending an app to the background is now applied for users of both FlutterActivity and the FlutterFragmentActivity. Until now it was not applied for FlutterFragmentActivity, causing an white screen if an app was using that activity.

Known Issues

Version 4.6.3.0

New Features

Added new WatermarkStyle enum that defines the style of the HERE watermark logo. The dark watermark should be used for custom styles that are brighter (like daytime) and the light watermark for darker custom schemes (like night or satellite based). Added a new loadScene() method to MapScene to accept the new enum together with a custom style.
MapCamera: Added FlyToOptions to customize the fly-to animation from current target GeoCoordinates to a new location. The durationInMs parameter defines how long the animation will run, the bowFactor defines a relative camera height for the ballistic curve that ranges from -1 < 0 (concave curve) to 0 (constant height) to 0 < 1 (convex curve). The maximum height can be achieved with a bowFactor of 1, the minimum with -1. Note that the height is relative to the distance between current target and new target to achieve a constant look regardless of the current zoom level.
Routing: Added sideOfStreetHint property to Waypoint. These optional GeoCoordinates indicate which side of the street should be used to reach the waypoint. For example, if the location is to the left of the street, the route will prefer using that side in case the street has dividers. Hence, if the street has no dividers, sideOfStreetHint is ignored.
Positioning: The kCLAuthorizationStatusNotDetermined status from iOS platform is now treated as LocationEngineStatus.missingPermissions. This status may be sent to listeners when the start() method of the LocationEngine is called. So now applications are not enforced to check the platform authorization status before starting to locate.
MapDownloader: Added possibility to delete downloaded map regions via the new deleteRegions() method that accepts a list of RegionId elements that should be deleted asynchronously.
MapDownloader: Added InstalledRegion class that holds information on installed regions. Added getInstalledRegions() method to get the new class.

Resolved Issues

Fixed: Currently, a Lane that is reserved for bus or bicycle does not contain a direction type.
Fixed: Navigation: Unlimited speed limits may not always be reported as expected.

Version 4.6.2.0

Highlights

The minimum supported Flutter version was raised from 1.17 to 1.20. The minimum supported Dart version is now 2.9.0.
Added a new Indoor Routing API (beta) which allows calculating routes inside private venues. The API supports routes from outside to a position inside a venue and from a position inside a venue to the outside. The API also allows showing the resulting routes on the map.

New Features

Introduced beta versions of new map style combinations for use with MapScene.loadScene(): "preview.normal.day.json", "preview.normal.night.json", "preview.hybrid.day.json" and "preview.hybrid.night.json".
Added new map item type: MapArrow elements can now be rendered on the map to indicate a direction. They can be added or removed like other map items via MapScene.
MapMarker items can now be made invisible once they overlap each other at certain zoom levels. They contain a new property with get/set isOverlapAllowed().
VisualNavigator: The visibility of a Route can be controlled with setRouteVisible(boolean). The property is exposed with isRouteVisible(). By default, if a route is set, it will be rendered when startRendering() is called, and removed with stopRendering(). It is possible to set or remove a route at any time, i.e., before or after calling startRendering(), and the route in the MapView will be updated accordingly.

API Changes

The free flow traffic layer is now rendering green traffic flow lines by default.
MapLoader: Deprecated the meaningless error MapLoaderError.duplicateCatalog.
VisualNavigator introduced a behavioral change: The transform center (also known as principal point) of the MapCamera is automatically adjusted during navigation for better viewing results. Calling startRendering() changes the principalPoint property of the MapCamera so that the current position indicator is placed slightly at the bottom of the MapView. It is restored to its original value when stopRendering() is called.

Resolved Issues

Fixed: When traffic flows are enabled, map gestures may behave slower than expected.
Fixed: Currently, a Lane that is reserved for bus or bicycle does not contain a direction type.
Fixed: Offline routing: Avoidance options are currently ignored.
Fixed: Offline routing: Ferry links are not extracted to separate sections.

Version 4.5.4.0

Highlights

The supported device specifications have been fine tuned and contain now more granular details on the supported devices. Details can be found in the About section of the Developer's Guide for this edition.

New Features

Extended walk routing options: Added PedestrianOptions.walkSpeedInMetersPerSecond property. Note that this feature is released as beta. By setting a walk speed you can calculate pedestrian routes specific for different walk profiles.
Searching for a CategoryQuery within a GeoCircle or GeoBox is no longer marked as a beta feature.
Added new map cache options to SDKOptions with SDKOptions.cacheSizeInBytes and SDKOptions.persistentMapStoragePath. Also available as key in manifest (com.here.sdk.cache_size_in_bytes, com.here.sdk.persistent_map_storage_path) on Android or plist on iOS (CacheSizeInBytes, PersistentMapStoragePath). With this you can control where to store cached map data and it also allows to specify the amount of data you want to reserve for caching.
Added new API methods to LocationEngine to control background positioning and battery saving options:
- set/get backgroundLocationAllowed(boolean): Enables or disables an application's background location updates. By default, background location updates are enabled if a application has background location capabilities.
- set/get backgroundLocationIndicatorVisible(boolean): Controls the visibility of a device's background location indicator. By default, the native background location indicator is visible, if an application has background location capabilities.
- set/get pauseLocationUpdatesAutomatically(boolean): Controls automatic pausing of location updates, for example, for improving the device's battery life at times when location data is unlikely to change. By default, automatic pausing of location updates is allowed.

API Changes

Changed PedestrianOptions(routeOptions, textOptions) constructor to PedestrianOptions(routeOptions, textOptions, 1.0) to support the new PedestrianOptions.walkSpeedInMetersPerSecond property (see above).

Known Issues

The VisualNavigator API is in an early development stage. More features and overall stabilization are planned for the next releases. Because of the pandemic situation full test coverage is currently blocked.
Updating an existing MapMarker with a completely new image causes the marker to disappear for a brief moment before being drawn with the new image.
The newly introduced zoom level behaves inconsistent across different devices as the shown level of detail depends on the physical screen size of a device.
Map caching may not work as expected for satellite map scheme. Existing tiles may be reloaded.
Transparency for MapPolylines is not supported.
Flutter's hot restart feature does not work when the map is moved. This results in an application freeze.
On iOS devices, MapViewPin instances disappear from MapView when changing device orientation. They reappear when moving the map.
MapViewPin instances cannot be removed after tilting and panning the map.
When traffic flows are enabled, map gestures may behave slower than expected.
A Maneuver.polyline list of GeoCoordinates has only one element for the last maneuver of a route.
MapMarker3D instances are only partly rendered when the camera is positioned too far from earth.
During navigation sometimes the next maneuver and voice instructions are triggered too early before roundabouts.
Starting LocationEngine on iOS devices fails when the device is in flight mode.
The jamFactor indicating TrafficSpeed is currently calculated linear without taking road types and other parameters into account.
Currently, a Lane that is reserved for bus or bicycle does not contain a direction type. Nevertheless, such a lane is included in the list of lanes. However, the lane type is not exposed yet. Therefore, it is recommended to omit lanes that do not contain at least one direction.
A MapPolyline may be unexpectedly rendered over a MapMarker.

Version 4.5.3.0

New Features

Added a NoticeCode that describes issues after a Route was calculated. For example, when a route should avoid tunnels, but the only possible route needs to pass a tunnel, the Route contains a notice that the requested avoidance of tunnels was violated. Therefore, it is recommended to always check a calculated Route for possible violations. The NoticeCode is part of a Notice object. A list of possible Notice objects can be accessed per Section of a Route. The list will be empty, when no violation occurred.
Addeded the ability to change the anchor point of a MapMarker with Anchor2D. By default, the marker is centered on the provided location and the anchor is at (0.5, 0.5). An anchor represents a point in a rectangle as a ratio of the marker's image width and height.
Added search for a CategoryQuery within a GeoCircle or GeoBox. Extended the existing CategoryQuery constructors to accept GeoCircle or GeoBox. Note that this feature is currently in BETA state.

API Changes

The lane assistance API was marked as BETA until further notice and thus there can be bugs and unexpected behavior. The API may change for new releases without a deprecation process.
- The lane list order was changed to always start with index 0 from the leftmost lane to the rightmost lane (last index). Currently, left-hand driving countries are not supported.

Known Issues

The VisualNavigator API is in an early development stage. More features and overall stabilization are planned for the next releases. Because of the pandemic situation full test coverage is currently blocked.

Version 4.5.2.0

Highlights

Added suppport for scooter route calculation with the new ScooterOptions. Note that this is a BETA feature. Using scooter routes for navigation is not yet supported.
Introduced a new lane assistance API to notify drivers during navigation which lane is recommended to reach the next maneuvers. Use the new LaneAsssistanceListener to receive LaneAssistance events that are fired along with each voice announcement.

New Features

Added new read-only property to MapPolyline with GeoPolyline get geometry.
Added DashPattern class to set dashed line styles for a MapPolyline.
Added a new property to MapPolyline to add support for fill colors when using dashed lines:
- ui.Color get dashFillColor
- set dashFillColor(ui.Color value)
Added cumulative orbit method to MapCamera to rotate the map around arbitrary view coordinates using relative orientation values with orbitBy(MapCameraOrientationUpdate delta, Point2D origin).

API Changes

Cache path to store map data is now unique per access key ID (which is unique per customer). The HERE SDK automatically appends the current version of the cache and the access key ID. If you want to keep existing cache data, it may be required to copy it from <cache-root> to <cache-root>/v1/<access-key-id>, as the current version of the cache is "v1".
Deprecated SDKNativeEngine.setAccessKey(access_key_id, access_key_secret). Use SDKNativeEngine.setAccessKeySecret(access_key_secret) instead, in combination with setting the access key ID via SDKOptions when constructing a new SDKNativeEngine.
Deprecated LocationUpdateListener. Use the new LocationListener instead.
Removed deprecated GeoCircle constructor that accepts single precision float type for radius.

Resolved Issues

Fixed: Embedded POI markers are not visible for the hybrid night map scheme.
Fixed: Pan gestures may receive a cancel event before a begin event.
Fixed: During guidance tracking mode, roads with unlimited speed are now correctly reported.

Version 4.5.1.0

Highlights

Improved cold startup time on certain devices like Samsung.
A new VisualNavigator class has been introduced. It contains the same functionality as the Navigator class, but offers support for a visual guidance experience. With startRendering() a 3D location marker is added that smoothly follows the current location on the map. The animation is interpolated. In addition, the MapOrientation is updated. When a Route is set, the camera automatically follows the direction arrow. With the new CameraTrackingMode, this can be turned off, for example, to let the user freely pan the map. When tracking is turned off, the direction arrow moves on, but the map is not moved. Once CameraTrackingMode is enabled again, the camera follows again the current location. Note that the Navigator class can be replaced by the VisualNavigator class without any further code adaptation as Navigator shares the same method signatures with the new VisualNavigator.

New Features

Introduced Maneuver.lengthInMeters() property to return the length of the maneuver.
Added new MapCameralimits with set targetArea(GeoBox value) and GeoBox get targetArea. This allows to set a target area preventing a user from moving away too much from a desired area of interest.
Added new MapCameralimits for bearing with AngleRange get bearingRange and set bearingRange(AngleRange value).
Introduced SectionTransportMode enum and Section.getSectionTransportMode method returning an instance of this type indicating now transport modes such as ferries. Section.getTransportMode has been deprecated, use the newly introduced method instead.
Search: Introduced SupplierReference type and Details.references property, which holds the list of supplier references to a place.

Known Issues

Version 4.5.0.0

Highlights

Added advanced positioning capabilities to find your current location. On Android this requires the user's consent to decide whether or not it's okay to collect data, while on iOS this is currently not necessary.
Switched to a more performant underlying map format that provides less size, less traffic and smaller download times. This new format does not require any adaptation on app side.
Added a new OfflineSearchEngine that works without internet connectivity upon previously cached maps. It supports key word search, category search, geocoding and reverse geocoding. For example, when no internet connection is available, an app may try to fallback to the OfflineSearchEngine to provide instant results - although connectivity is be temporarily lost.
Added route calculation for electric vehicles (EV). It's now possible to calculate the energy consumption per route section according to the given consumption model (supported for electric cars and trucks). Charging stations are automatically added to the calculated route as waypoints to ensure that the electric vehicle doesn't run out of energy along the way (supported for electric cars).

New Features

Added LogAppender interface to insert your own log class into the SDKNativeEngine. This way you can log HERE SDK messages for various predefined log levels even on release builds.
Added in Navigator a static method to query the list of available languages for maneuver notifications: List<LanguageCode> Navigator.getAvailableLanguagesForManeuverNotifications().
Added a scale property to change the size of a MapMarker3D.
Added camera tilt limits with MapCameraLimits.setMaxTilt(double degreesFromNadir) and MapCameraLimits.setMinTilt(double degreesFromNadir).
Added camera zoom limits with MapCameraLimits.setMaxZoomLevel(double zoomLevel) and MapCameraLimits.setMinZoomLevel(double zoomLevel).
Added new methods to calculate routes for electric vehicles (car and trucks are supported): RoutingEngine.calculateRoute(List<Waypoint>, EVCarOptions, CalculateRouteCallback), RoutingEngine.calculateRoute(List<Waypoint>, EVTruckOptions, CalculateRouteCallback).
Added the following classes and fields to support EV routing (see above):
- BatterySpecifications - parameters that describe the electric vehicle's battery.
- ChargingConnectorAttributes - details of the connector that is suggested to be used for charging.
- ChargingConnectorType - enumeration of the available charging connector types.
- ChargingStation - charging station data.
- ChargingSupplyType - enumeration of available charging supply types.

- PostActionType - enumeration of available post action types.
- PostAction - an action that must be done after arrival.
- RoutePlaceType - shows whether the place on the route (such as departure or arrival) is a charging station or a regular place.
- Arrival.type - the type of the arrival place.
- Arrival.chargeInKilowattHours - battery charge at arrival.
- Arrival.chargingStation - charging station data at arrival.
- Departure.type - the type of the departure place.
- Departure.chargeInKilowattHours - battery charge at departure.
- Departure.chargingStation - charging station data at departure.
- Section.postActions - actions that must be done after the arrival.
- Section.evDetails - additional section information that is available for electric vehicles.

API Changes

The minimum supported iOS version was increased from 12.0 to 12.4.
For custom map styles HERE Style Editor 0.26 is required.
Changed splash screen to be grey instead of black. This improves the experiences on devices where cold start takes longer.
Deprecated the LocationProvider interface and the Navigator constructors that accept a LocationProvider as parameter. A Navigator can now be construced from an empty constructor.
A Navigator now implements the sdk.core.LocationListener interface.
Deprecated onLocationTimeout() of sdk.core.LocationListener - it is no longer needed and the necessary timeout handling is now done internally inside the Navigator implementation.
Removed a deprecated GeoCoordinates constructor, use the previously introduced counterpart instead.
Removed a deprecated Anchor2D constructor, use the previously introduced counterpart instead.
Deprecated in Navigator the method List<LanguageCode> getSupportedLanguagesForManeuverNotifications(), use List<LanguageCode> Navigator.getAvailableLanguagesForManeuverNotifications() instead.

Resolved Issues

Fixed: After orientation changes coordinate conversions may return incorrect values.
Fixed: During navigation sometimes the nextRoadName or nextRoadNumber are not available when the name of the street/road is a route number. In such a case, the next Maneuver indicates an 'unknown road'.
Fixed: When imperial unit system is selected along with 'EN US' language code, then RouteTextOptions returns 'ft' as unit, but voice guidance uses 'yards'.
Fixed: For some regions the speed limit value can be unexpectedly null on highways. Roads with no speed limit are now correctly indiciated during navigation.
Fixed: During navigation, tunnel extrapolation may not work as expected.
Fixed: Category search along a route will crash when the GeoCorridor.polyline list parameter is empty.
Fixed issues for map matching with no or unstable heading information. During navigation, map matching now works even when no heading information is provided or when the speed is very low.

Version 4.4.3.0

Highlights

Kinetic map panning behavior was greatly improved. Now, when swiping the map moves slower which results in a more natural feel.
Certain areas can now be excluded from route calculation with AvoidanceOptions that contain an avoidAreas list holding GeoBox items which routes should not cross.

New Features

Added optional Suggestion.getHref() to get a direct link to discover more details. It is available when the suggestion result type is category or chain.

- Added Departure class with the following fields:
  - waypointIndex
  - originalCoordinates
  - mapMatchedCoordinates
- Added Arrival class with the following fields:
  - waypointIndex

Support for interactive private venues has been introduced. This feature is available for building owners upon request.

New Features

Added to the MapCamera class the method: setTargetOrientation(MapCameraOrientationUpdate orientation) to set only the target orientation in relation to the camera.
By default, polylines are rendered in the order as they have been added to the map. This can now be changed at runtime by setting the draw order. It's now also possible to change the width and outline width at runtime. For this, the following methods have been added to the MapPolyline class:
- set drawOrder(int value) to set the DrawOrder for a MapPolyline.
- int get drawOrder to get the DrawOrder for a MapPolyline.
- set width(double value) to set the LineWidth for a MapPolyline.
- double get width to get the LineWidth for a MapPolyline.

Search for places by category along a route: Added the CategoryQuery structure that accepts the GeoCorridor option in its constructors with the filter parameter CategoryQuery.withFilterAndCorridorArea(List<PlaceCategory> categories, String filter, GeoCorridor corridorArea) and without the filter parameter CategoryQuery.withCorridorArea(List<PlaceCategory> categories, GeoCorridor corridorArea) to enable category search along a route. This feature is in BETA state.
Added to the Details class the method: List<PlaceCategory> getPrimaryCategories() to get a place category from the result of a search query.

Resolved Issues

Fixed issue with hot restart not working correctly. Now, the hot restart functionality is working properly without the need to restart the app.
Fixed: Rendering order for MapMarker3D is not yet supported, so the marker may appear below building footprints. Now, the rendering order for MapMarker3D is supported and the marker no longer appears below building footprints.
Fixed several rendering issues related to map items.
Fixed issue with non-working gestures after a map view is recreated.

Known Issues

Map caching may not work as expected for satellite map scheme. Existing tiles may be reloaded.
SearchEngine: Place.getId() is empty for reverse geocoding results.
Transparency for MapPolylines is not supported.
3d marker is not aligned with the road when using the map matched position.
During turn-by-turn navigation, a NavigableLocation may not contain map-matched geographic coordinates for some regions due to data issues.
When the pick radius for pickMapItems() is set to 1000 or higher, an app may crash when picking map polylines.
For places that are obtained from the Suggestion class, the geographic coordinates always contain a latitude and a longitude equal to 0. An additional places request is needed to obtain the coordinates.

API Changes

Removed the android.permission.READ_EXTERNAL_STORAGE and android.permission.WRITE_EXTERNAL_STORAGE permissions from the SDK's Android manifest file.
Internally, the HERE SDK switched from "UpperCamelCase" to "snake_case". This has no effect on the public API, but if you have the HERE SDK plugin folder under source control, please make sure to enable case sensitivity - otherwise these naming changes will be ignored when committing the folder.

Resolved Issues

Fixed: Error when loading a SVG file into a MapImage. Now, SVG files that are stored in the assets directory can be loaded into a MapImage with the method MapImage.withFilePathAndWidthAndHeight("assets/my_svg_image.svg", 100, 100) (call example).

Known Issues

Map caching may not work as expected for satellite map scheme. Existing tiles may be reloaded.
SearchEngine: Place.getId() is empty for reverse geocoding results.
