Custom markers with Flutter Google Maps plugin

Algo asi https://www.youtube.com/watch?v=ajuo0HjN3lY&t=905s

BitmapDescriptor icon;


@override
  void initState() {
    getIcons();
    super.initState();
  }


// Cargar imagen del Marker
  getIcons() async {
    var icon = await BitmapDescriptor.fromAssetImage(
        ImageConfiguration(devicePixelRatio: 3.2),
        "assets/images/markeruser.png");
    setState(() {
      this.icon = icon;
    });
  }


// Crear Marker
  createMarkers() {
    markers.add(
      Marker(
        markerId: MarkerId("MarkerCurrent"),
        position: currentLocation,
        icon: icon,
        infoWindow: InfoWindow(
            title: "Mi Ubicacion",
            snippet:
                "Lat ${currentLocation.latitude} - Lng ${currentLocation.longitude}"),
        draggable: true,
        onDragEnd: onDragEnd,
      ),
    );
  }

BitmapDescriptor customIcon;

// make sure to initialize before map loading
BitmapDescriptor.fromAssetImage(ImageConfiguration(size: Size(12, 12)),
        'assets/images/car-icon.png')
    .then((d) {
  customIcon = d;
});

final nearbyCarsLocation = [
  LatLng(24.9286825, 67.0403249),
  LatLng(24.985577, 67.0661056), //24.9294892,67.0391903,18.73z
];

void _getNearByCars() {

  for (var i = 0; i < nearbyCarsLocation.length; i++) {
    var now = new DateTime.now().millisecondsSinceEpoch;
    _markers.add(Marker(
      markerId: MarkerId(nearbyCarsLocation[i].toString() + now.toString()),
      position: nearbyCarsLocation[i],
      // infoWindow: InfoWindow(title: address, snippet: "go here"),
      icon: customIcon ));
  }
  notifyListeners();
}

Hope this will help in getting custom nearby localities

I'm using:

controller.addMarker(MarkerOptions(
  icon: BitmapDescriptor.fromAsset("images/restaurant.png"),
  position: LatLng(40.017870, -105.278350),
));

It works fine on Android, but it doesn't work on iOS.

BitmapDescriptor.fromAsset is deprecated

Use BitmapDescriptor.fromAssetImage instead.

It respects the device DPI when choosing the appropriate asset. See Declaring resolution-aware image assets.
