title: How to change the icon size of Google Maps marker in Flutter?
body: <p>I am using <code>google_maps_flutter</code> in my flutter app to use google map I have custom marker icon and I load this with <code>BitmapDescriptor.fromAsset("images/car.png")</code> however my icon size on map is too big I want to make it smaller but I couldn't find any option for that is there any option to change custom marker icon.
  here is my flutter code:</p>
  
  <pre><code>mapController.addMarker(
          MarkerOptions(
            icon: BitmapDescriptor.fromAsset("images/car.png"),
  
            position: LatLng(
              deviceLocations[i]['latitude'],
              deviceLocations[i]['longitude'],
            ),
          ),
        );
  </code></pre>
