Usage #

Inspired by the simplicity of Leaflet.js, we can integrate maps in our flutter project with as simple as adding these lines of code.

import 'package:universe/universe.dart';

U.OpenStreetMap(
  center: [-6.175329, 106.827253],
  type: OpenStreetMapType.HOT,
  zoom: 15,

MapBox #

MapBox
U.MapBox(
  // get your access token from https://account.mapbox.com/access-tokens/
  accessToken: '',
  center: [-6.175329, 106.827253],
  type: MapBoxType.Street,
  zoom: 15,
)

You can get your own MapBox access token from here. Please always use your own access token in your projects.

Custom Map Provider #

We can call U.Map directly to use maps with custom map providers. Here is an example of using custom map from OpenTopoMap.

U.Map(
  center: [51.555158, -0.108343],
  base: U.TileLayer('https://{s}.tile.opentopomap.org/{z}/{x}/{y}.png',
    attribution: 'Map data: &copy; OpenStreetMap contributors, SRTM | Map style: &copy; OpenTopoMap',
    maxZoom: 17,
  ),
)

Multi TileLayer Maps #

Multi TileLayer

We can create maps with multiple tile layers. Here is an example of using Humanitarian OpenStreetMap combined with map tiles from SafeCast and OpenRailwayMap.

U.OpenStreetMap(
  type: OpenStreetMapType.HOT,
  center: [48.858236, 2.294477],
  zoom: 12,
  tiles: [
    // add environmental measurements map layer from SafeCast (http://safecast.org/)
    U.TileLayer(
      'https://s3.amazonaws.com/te512.safecast.org/{z}/{x}/{y}.png', 
      attribution: 'Data: &copy; OpenStreetMap contributors | Style: &copy; SafeCast',
      maxZoom: 16,
    ),
    // add map layer from OpenRailwayMap
    U.TileLayer(
      'https://{s}.tiles.openrailwaymap.org/standard/{z}/{x}/{y}.png', 
      attribution: 'Data: &copy; OpenStreetMap contributors | Style: &copy; OpenRailwayMap',
      maxZoom: 19,
    ),
  ],
)

Markers #

Here is a simple way of adding marker to universe maps.

U.OpenStreetMap(
  center: [51.555158, -0.108343],
  type: OpenStreetMapType.HOT,

  markers: U.MarkerLayer([51.556669, -0.108123]),

Live Maps #

U.OpenStreetMap(
  center: [51.555158, -0.108343],
  type: OpenStreetMapType.HOT,
  zoom: 15,
  live: true,
)

Live Maps Without AutoMoving #

The default behavior of Live Map is always move the center of the maps to user's current location.

If you want to go live (always searching for user's current location and show location indicator to that location), but don't want to move the center of the maps, you can set parameter moveWhenLive to false.

U.GoogleMap(
  type: GoogleMapType.Street,
  center: [-6.169976, 106.830979],
  zoom: 16,
  live: true,
  // moveWhenLive: false will make the map live (constantly search for user location),
  // set the location indicator to current user location, but does not 
  // move the center of the maps automatically to that location.

  // moveWhenLive has default value set to true
  moveWhenLive: false,
)

Live Map without Auto Moving

Live Stream Maps #

We can let the map live while also listening to current user's location by subscribing to liveStream of MapController.

_liveSubs = _mapController.liveStream?.listen((latlng) { 
  print('Current location: $latlng');
});

See the complete example at Live Stream Map

Static Maps #

U.OpenStreetMap(
  center: [51.555158, -0.108343],
  type: OpenStreetMapType.Mapnik,
  zoom: 15,
  interactive: false,
)

MapController #

We can use custom controller in our universe maps.

final _mapController = MapController();
U.OpenStreetMap(
  controller: _mapController,
  center: [51.555158, -0.108343],
  zoom: 15,
)

And use that controller to listen the positionStream to get current position and current zoom of our map. We can also programmatically move, zoom, rotate or find location using the map controller.

// listen everytime the map data changes (move or zoom)
_mapController.positionStream?.listen((data) {
  // current center of the map
  // print(data.center); 
  // current zoom level of the map
  // print(data.zoom);
});
