Add permissions to your android AndroidManifest.xml.

<manifest xmlns:android...>
  ...
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Complete Examples #

Learn complete examples in this folder for many use cases of using Universe. Or install the example apk and try it on your device: universe.apk.

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,
)

OpenStreetMap #

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

// List of available OpenStreetMapType

// OSM Mapnik

// OSM Germany
OpenStreetMapType.DE
// OSM Switzerland

// OSM France

// Humanitarian OSM

Google Maps #

U.GoogleMap(
  center: [-6.175329, 106.827253],
  type: GoogleMapType.Street,
  zoom: 15,
)

// List of available GoogleMapType

GoogleMapType.Street 
GoogleMapType.Satellite
GoogleMapType.Hybrid
GoogleMapType.Terrain

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.

// List of available MapBoxType

MapBoxType.Basic
MapBoxType.Street 
MapBoxType.Satellite
MapBoxType.Hybrid
MapBoxType.Outdoors
MapBoxType.Dark
MapBoxType.Light
MapBoxType.Bright

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,
  ),
)

Complete Custom Map example

Multi TileLayer Maps #

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,
  zoom: 15,
  markers: U.MarkerLayer([51.556669, -0.108123]),
)

Live Maps #

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

Complete live maps examples:

Live Map with Location Marker

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,
)

Complete static maps examples:

Simple Static Map
Static Map with Marker
Static Map with Rotation

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);
});

Circle #

Here is a simple example of painting a circle to universe maps.

U.OpenStreetMap(
  center: [-6.170039, 106.8241],
  zoom: 15,
  // by default, CircleLayer will use style from theme primaryColor
  circles: U.CircleLayer(
    [-6.170039, 106.8241],
    radius: 160,
  ),
)

Custom Controls #

Universe maps come with default controls: compass, locator, scale and location indicator. But we can override this controls with our own controls to make it align with our app theme.
