Overview

Welcome to the Developer's Guide for the HERE SDK for Flutter, version 4.3.0.0 (Explore Edition). Here you can find all necessary information to start building immersive location-aware apps for iOS and Android today!

This is a BETA release.

Why Use the HERE SDK for Flutter?

The new HERE SDK for Flutter enables you to build powerful map applications for iOS and Android from a single codebase written in Dart. Bundled along with it are many HERE assets, available for customers to integrate with their own apps. It consumes data from the HERE platform incorporating microservices and highly modularized components. The HERE SDK for Flutter belongs to the HERE SDK product family, which also includes the HERE SDK for iOS and the HERE SDK for Android.

  • Backed by more than 30 years of expertise in mapping technology, the new lightweight HERE SDK for Flutter provides you with instant access to the freshest map data of the highest quality, consistency and accuracy.
  • Build captivating native applications and benefit from one of the world’s most accurate and interactive map data that is captured via a comprehensive and precise industrial process with the HERE True vehicles.
  • Explore maps that are fast and smooth to interact with, pan/zoom across map views of varying resolutions, and enable the display of various elements such as routes and POIs on highly customizable map views.

Which Edition is Best for Me?

We have made the HERE SDK for Flutter available in two different editions, the Explore Edition and the Navigate Edition. In comparison to the Explore Edition, the Navigate Edition provides additional premium features such as turn-by-turn navigation.

Both editions include a Premium Renderer which offers visually appealing true 3D maps that provide a smooth map experience and highly performant map rendering tailored for high-end devices. Benefit from premium features such as multiple map view instances, an integrated tool chain for map customization, full 3D camera control and seemless map scheme switches.

For now, the Navigate Edition is only available upon request. Please contact your HERE representative to receive access including a set of evaluation credentials.
