This flutter plugin allow you to embed Mapbox Map to your flutter app. This plugin uses the latest
version of the Mapbox Map SDK so that you can experience all the latest feature introduced.
Currently this plugin only support android platform. It is based on Mapbox Map SDK
versionv10.10.0
You have to include your mapbox map secret token and access token in order to use the mapbox map.
Include your Mapbox Map Secret token to your gradle.properties. You can get your Mapbox Map
secret token from your mapbox account page. It starts with sk.
MAPBOX_SECRET_TOKEN=<your-mapbox-map-secret-token>
Also include this line of code in your project level build.gradle file
allprojects {
repositories {
google()
mavenCentral()
// Add this line
maven {
url 'https://api.mapbox.com/downloads/v2/releases/maven'
authentication {
basic(BasicAuthentication)
}
credentials {
username = "mapbox"
password = project.properties['MAPBOX_SECRET_TOKEN']
}
}
}
}
Include your Mapbox Map access token to string.xml file of the app/src/main/res/values/
directory of android section It starts with pk.
<string name="mapbox_access_token">your-access-token</string>
This plugin is not available in IOS yet.
You have to use MapboxMap() widget to add map in your page.
MapboxMap(
initialCameraPosition: CameraPosition(
center: Point.fromLatLng(29.837785, 87.538961),
zoom: 15.0,
animationOptions: AnimationOptions.mapAnimationOptions(
startDelay: 0,
duration: const Duration(milliseconds: 750),
),
),
style: MapStyle.light,
showCurrentLocation: true,
onMapCreated: (controller) {
// controller - MapboxMapController instance
},
onStyleLoaded: () async {
final isAlreadyAdded =
await _controller?.isSourceExist("my-data-source") ?? false;
if (!isAlreadyAdded) {
_addGeoJson();
}
},
onStyleLoadError: (err) {
if (kDebugMode) {
print(
"[onStyleLoadError] ---> $err");
}
},
onMapClick(point, coordinates) {},
onMapLongClick(point, coordinates) {},
onFeatureClick: (details) {
// details contain:
// - point (lat and lng),
// - coordinates (x and y screen coordinate)
// - feature (Feature object)
// - source
// - sourceLayer
},
onFeatureLongClick: (details) {},
),
This api supports all the style sources that is supported by the latest Mapbox Map SDK. You can add the style source like this.
await _controller.addSource<GeoJsonSource>(
source: GeoJsonSource(
sourceId: "geojson-source-id",
url: "https://d2ad6b4ur7yvpq.cloudfront.net/naturalearth-3.3.0/ne_10m_land_ocean_label_points.geojson",
sourceProperties: GeoJsonSourceProperties(
cluster: true,
clusterRadius: 50,
clusterMaxZoom: 14,
maxZoom: 20,
),
),
)
Like sources, this api also supports all the style layers that is supported by the latest Mapbox Map SDK. You can add the style layer like this.
// Circle Layer
await _controller.addLayer<CircleLayer>(
layer: CircleLayer(
layerId: "my-layer-id",
sourceId: "geojson-source-id",
layerProperties: CircleLayerProperties(
circleColor: [
'case',
[
'boolean',
['has', 'point_count'],
true
],
'red',
'blue'
],
circleColorTransition: StyleTransition.build(
delay: 500,
duration: const Duration(milliseconds: 1000),
),
circleRadius: [
'case',
[
'boolean',
['has', 'point_count'],
true
],
15,
10
],
circleStrokeWidth: [
'case',
[
'boolean',
['has', 'point_count'],
true
],
3,
2
],
circleStrokeColor: "#fff",
circleTranslateTransition: StyleTransition.build(
delay: 0,
duration: const Duration(milliseconds: 1000),
),
),
),
);
// Symbol Layer
await _controller.addLayer<SymbolLayer>(
layer: SymbolLayer(
layerId: "symbol-layer-example",
sourceId: "geojson-source-id",
layerProperties: SymbolLayerProperties(
textField: ['get', 'point_count_abbreviated'],
textSize: 12,
textColor: '#fff',
iconSize: 1,
iconAllowOverlap: true,
),
),
);
You can add style image from your assets or from the url. Svg image is not supported yet.
// Add image stored on assets
await _controller.addStyleImage<LocalStyleImage>(
image: LocalStyleImage(
imageId: "icon",
imageName: "assets/images/your-image.png",
),
);
// Add image from url
await _controller.addStyleImage<NetworkStyleImage>(
image: NetworkStyleImage(
imageId: "icon",
url: "https://example.com/icon.png",
),
);
You can add circle, point/symbol, polyline and polygon annotations.
// Add circle annotation
final id = await _controller?.addAnnotation<CircleAnnotation>(
annotation: CircleAnnotation(
annotationOptions: CircleAnnotationOptions(
point: Point.fromLatLng(27.321, 82.323),
circleRadius: 20.0,
circleColor: "red",
circleStrokeWidth: 2.0,
circleStrokeColor: "#fff",
data: {"id": 124, "name": "testing circle"},
draggable: true,
),
),
);
// Add point annotation
// You have three options for image source that you want to show
// iconUrl: Url of the icon other than .svg format
// iconPath: If you want to use image from assets then you can provide path here
// iconImage: If you want to use image added through style image, then provide imageId here
final id = await _controller?.addAnnotation<PointAnnotation>(
annotation: PointAnnotation(
iconUrl: "https://yourdomain.com/icons/name.png",
or
iconPath: "assets/icons/name.png",
or
iconImage: "image-Id-given-while-adding-style-image",
annotationOptions: PointAnnotationOptions(
point: Point.fromLatLng(27.321, 82.323),
iconColor: "red",
iconSize: 1.2,
data: {"id": 124, "icon": "icon.png", "color": "#fff"},
draggable: true,
),
),
);
// Add Polyline Annotation
final id = await _controller?.addAnnotation<PolylineAnnotation>(
annotation: PolylineAnnotation(
annotationOptions: PolylineAnnotationOptions(
points: [Point.fromLatLng(27.412, 82.331), Point.fromLatLng(27.432, 82.321)],
lineColor: "red",
lineGapWidth: 2,
lineSortKey: 0.3,
lineWidth: 2.0,
data: {"id": 124, "icon": "icon.png", "color": "#fff"},
draggable: true,
),
),
);
If you want to show the current location indicator (location puck) on map then you have to
set showCurrentLocation: true in MapboxMap().
By default, the Maps SDK uses the Android GPS and Network Providers to obtain raw location updates.
In applications using Android 11, the raw location updates might suffer from precision issues. In
order to get accurate location you can add this dependency to your app's build.gradle.
For more info:
implementation "com.google.android.gms:play-services-location:18.0.0"
And these permissions to the AndroidManifest.xml
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
