flutter_map

A Dart implementation of Leaflet for Flutter apps.

Usage

Add flutter_map to your pubspec:

dependencies:
  flutter_map: any # or the latest version on Pub

Configure the map using MapOptions and layer options:

  Widget build(BuildContext context) {
    return new FlutterMap(
      options: new MapOptions(
        center: new LatLng(51.5, -0.09),
        zoom: 13.0,
      ),
      layers: [
        new TileLayerOptions(
          urlTemplate: "https://api.tiles.mapbox.com/v4/"
              "{id}/{z}/{x}/{y}@2x.png?access_token={accessToken}",
          additionalOptions: {
            'accessToken': '<PUT_ACCESS_TOKEN_HERE>',
            'id': 'mapbox.streets',
          },
        ),
        new MarkerLayerOptions(
          markers: [
            new Marker(
              width: 80.0,
              height: 80.0,
              point: new LatLng(51.5, -0.09),
              builder: (ctx) =>
              new Container(
                child: new FlutterLogo(),
              ),
            ),
          ],
        ),
      ],
    );
  }

Configure the map to use Azure Maps by using the following MapOptions and layer options:

Widget build(BuildContext context) {
    return new FlutterMap(
      options: new MapOptions(
        center: new LatLng(51.5, -0.09),
        zoom: 13.0,
      ),
      layers: [
        new TileLayerOptions(
          urlTemplate: "https://atlas.microsoft.com/map/tile/png?api-version=1&layer=basic&style=main&tileSize=256&view=Auto&zoom={z}&x={x}&y={y}&subscription-key={subscriptionKey}",
          additionalOptions: {
            'subscriptionKey': '<YOUR_AZURE_MAPS_SUBSCRIPTON_KEY>'
          },
        ),
        new MarkerLayerOptions(
          markers: [
            new Marker(
              width: 80.0,
              height: 80.0,
              point: new LatLng(51.5, -0.09),
              builder: (ctx) =>
              new Container(
                child: new FlutterLogo(),
              ),
            ),
          ],
        ),
      ],
    );
  }

To use Azure Maps you will need to setup an account and get a subscription key

Run the example

See the example/ folder for a working example app.

To run it, in a terminal cd into the folder. Then execute ulimit -S -n 2048 (ref). Then execute flutter run with a running emulator.

Offline maps

Follow this guide to grab offline tiles
Once you have your map exported to .mbtiles, you can use mbtilesToPng to unpack into /{z}/{x}/{y}.png. Move this to Assets folder and add asset directories to pubspec.yaml. Minimum required fields for offline maps are:

Widget build(ctx) {
  return FlutterMap(
    options: MapOptions(
      center: LatLng(56.704173, 11.543808),
      zoom: 13.0,
      swPanBoundary: LatLng(56.6877, 11.5089),
      nePanBoundary: LatLng(56.7378, 11.6644),
    ),
    layers: [
      TileLayerOptions(
        tileProvider: AssetTileProvider(),
        urlTemplate: "assets/offlineMap/{z}/{x}/{y}.png",
      ),
    ],
  );
}

Make sure PanBoundaries are within offline map boundary to stop missing asset errors.
See the flutter_map_example/ folder for a working example.

Note that there is also FileTileProvider(), which you can use to load tiles from the filesystem.

Plugins

flutter_map_marker_cluster: Provides Beautiful Animated Marker Clustering functionality
user_location: A plugin to handle and plot the current user location in FlutterMap
