Minimum Requirements

The HERE SDK for Flutter enables you to write apps for Android and iOS. Make sure to meet the minimum requirements for each platform as listed below. Note that the HERE SDK for Flutter does not support web and desktop apps.

• The minimum supported Flutter version is 2.8.0. The latest stable Flutter version that works with the HERE SDK is 2.10.2.
• The minimum supported Dart version is 2.15.0. The latest stable Dart version that works with the HERE SDK is 2.16.1.

Other versions may also work, but are not guaranteed to work. As of now, only the stable Flutter channel is supported.

It is recommended to use the Dart version that is bundled with Flutter.

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.

The HERE SDK plugin uses ffi: >=1.0.0 <=1.1.2, see also the pubspec.yaml file inside the plugin folder. This may lead to incompatibilities with plugins from other vendors that use a different Dart FFI version that lies outside this range.

Null safety is supported by default. It can be optionally disabled, by adding the following comment on top of any Dart file: // @dart=2.9.

For minimum and recommended device hardware specifications, please check the devices section below.

Android

• The minimum Android API level supported by the HERE SDK for Flutter is API 21, Android 5.0 (Lollipop), which allows you to reach more than approximately 90% of all Android devices on the market.

iOS

• The HERE SDK for Flutter supports iOS 12.4 and iPadOS or higher.
• Only simulators running iOS 13.0 or higher are supported.
• As an absolute minimum for development, you must use macOS macOS Catalina, Xcode 12.4, Swift 5.3.2 and CocoaPods 1.10 - or higher.

Supported Devices

The HERE SDK for Flutter enables you to write apps for Android and iOS devices. Make sure to compare your target devices to the supported devices for each platform as listed below.

Android

Most devices that are from 2015 or newer are supported. Only in rare rases such devices may not work - for example, when they do not meet the minimum device specifications (see below). Devices that are older than 2015 may still work, but are not guaranteed to work.

• The HERE SDK for Flutter supports Android 32-bit devices with x86 or ARMv7 architecture and 64-bit devices with x86_64 or ARM64/v8 architecture.
• Additional requirements:
  • Support for OpenGL ES 3.0 or higher (applies also to emulators).
  • Minimum supported hardware specifications:
    • RAM: At least 1 GB memory.
    • ROM: At least 60 MB free disk space for the uncompressed installation size (plus enough free disk space to operate the device in general).
    • GPU: All GPUs that support OpenGL ES 3.0.
  • Recommended hardware specifications:
    • RAM: At least 3 GB memory.
    • ROM: At least 60 MB free disk space for the uncompressed installation size plus 256 MB to cache map data (plus enough free disk space to operate the device in general).
    • GPU: We recommend at least an Adreno 4xx, Mali T7x or G7x graphics processing unit or newer.

iOS

• The HERE SDK for Flutter supports iOS ARM64 / 64-bit architectures incorporating Apple's A7 chip or newer. This means that all iOS devices starting from the iPhone 5s (which was released in 2013) are supported as all these devices contain sufficient RAM and CPU/GPU power.
• The x86_64 and simulator-arm64 architecture is supported for simulators. Therefore, this includes M1 and non-M1 machines.
• It is recommended to allow at least 60 MB disk space for the uncompressed installation size of an app plus 256 MB to cache map data on the disk.
