Universe #
The easy & flexible way to use interactive maps in Flutter. Inspired by Leaflet.js.
Getting Started #
Add dependency to your flutter project:
dependencies:
universe: ^0.0.5-nullsafety.1
dependencies:
universe:
git:
url: git://github.com/salkuadrat/universe.git
Then run flutter pub get.
Android Permissions #
Add Internet & Location permissions to your AndroidManifest.xml.
<manifest xmlns:android...>
...
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<application ...
</manifest>
Example Project #
There is a complete examples in the example folder.
Check it out to learn the many use cases of using Universe library.
You can also try a working example by installing universe.apk.
Usage #
Inspired by the simplicity of Leaflet.js, we can add maps functionality to our flutter project with as simple as adding this 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
OpenStreetMapType.CH
// 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: © OpenStreetMap contributors, SRTM | Map style: © OpenTopoMap',
maxZoom: 17,
),
)
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: © OpenStreetMap contributors | Style: © SafeCast',
maxZoom: 16,
),
// add map layer from OpenRailwayMap
U.TileLayer(
'https://{s}.tiles.openrailwaymap.org/standard/{z}/{x}/{y}.png',
attribution: 'Data: © OpenStreetMap contributors | Style: © OpenRailwayMap',
maxZoom: 19,
),
],
)

Markers #
Here is a simple example of adding a 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:
Default Live Map
Simple Live Map
Live Map with Location Marker
Live Maps Without AutoMoving #
The default behavior of Live Map will always move the center of the maps to user's current location.
If we 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, we 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,
)
Static Maps #
U.OpenStreetMap(
center: [51.555158, -0.108343],
type: OpenStreetMapType.Mapnik,
zoom: 15,
interactive: false,
)
Complete static maps examples:

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 the 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);
});

zoom: 15,
// by default, CircleLayer will use style from theme primaryColor
circles: U.CircleLayer(
