How to change the icon size of Google Maps marker in Flutter?

Question

I am using google_maps_flutter in my flutter app to use google map I have custom marker icon and I load this with BitmapDescriptor.fromAsset(\"images/car.

Answer 1

Try BitmapDescriptor.fromAssetImage. It will ignore the image size as well.

BitmapDescriptor.fromAssetImage(
            ImageConfiguration(size: Size(32, 32)), 'assets/car.png')
        .then((onValue) {
      setState(() {
        markerIcon = onValue;
      });
    });

Also using default configuration fails.

loadMarkerImage(BuildContext context) {
    var config = createLocalImageConfiguration(context, size: Size(30, 30));
    BitmapDescriptor.fromAssetImage(config, 'assets/car.png')
        .then((onValue) {
      setState(() {
        markerIcon = onValue;
      });
    });
  }
