Flutter Mapbox GL

Please note that this project is community driven and is not an official Mapbox product. We welcome feedback and contributions.

This Flutter plugin allows to show embedded interactive and customizable vector maps inside a Flutter widget. For the Android and iOS integration, we use mapbox-gl-native. For web, we rely on mapbox-gl-js. This project only supports a subset of the API exposed by these libraries.

Running the example app

Install Flutter and validate its installation with flutter doctor
Clone the repository with git clone [email protected]:mapbox/flutter-mapbox-gl.git
Add a Mapbox access token to the example app (see next section)
Connect a mobile device or start an emulator, simulator or chrome
Locate the id of a the device with flutter devices
Run the app with `cd flutter_mapbox/example && flutter packages get && flutter run -d {device_id}``

Adding a Mapbox Access Token

This project uses Mapbox vector tiles, which requires a Mapbox account and a Mapbox access token. Obtain a free access token on your Mapbox account page.

Even if you do not use Mapbox vector tiles but vector tiles from a different source (like self-hosted tiles) with this plugin, you will need to specify any non-empty string as Access Token as explained below!

Android

Add Mapbox access token configuration in the application manifest example/android/app/src/main/AndroidManifest.xml:

<manifest ...
  <application ...
    <meta-data android:name="com.mapbox.token" android:value="YOUR_TOKEN_HERE" />

iOS

Add Mapbox access token configuration to the application Info.plist example/ios/Runner/Info.plist:

<key>io.flutter.embedded_views_preview</key>
<true/>
<key>MGLMapboxAccessToken</key>
<string>YOUR_TOKEN_HERE</string>

Web

Add Mapbox access token configuration to index.html example/web/index.html:

<body>
  ...
  <script>
    mapboxgl.accessToken = 'YOUR_TOKEN_HERE';
  </script>
</body>

Using the SDK in your project

Offline Sideloading

Support for offline maps is available by "side loading" the required map tiles and including them in your assets folder.

Create your tiles package by following the guide available here.
Place the tiles.db file generated in step one in your assets directory and add a reference to it in your pubspec.yml file.

   assets:
     - assets/cache.db

Call installOfflineMapTiles when your application starts to copy your tiles into the location where Mapbox can access them. NOTE: This method should be called before the Map widget is loaded to prevent collisions when copying the files into place.

    try {
      await installOfflineMapTiles(join("assets", "cache.db"));
    } catch (err) {
      print(err);
    }

Location features

To enable location features in an iOS application:

If you access your users' location, you should also add the following key to your Info.plist to explain why you need access to their location data:

<key>NSLocationWhenInUseUsageDescription</key>
<string>[Your explanation here]</string>

Mapbox recommends the explanation "Shows your location on the map and helps improve the map".
