If you want to display your custom cluster marker on Google Maps, you need to open following file:

Project_HOME > lib > hooks_v2.dart

Look for the getCustomClusterMarkerIconHook() method. You are provided with the customClusterMarkerIconHook with 2 additional parameters i.e. BuildContext and clusterSize. Define your cluster marker icon here and return it instead of returning null.

After modifications, restart the app and the changes will reflect on Maps.

@override
  CustomClusterMarkerIconHook getCustomClusterMarkerIconHook() {
    CustomClusterMarkerIconHook customClusterMarkerIconHook = (BuildContext context, int clusterSize) {

      return null;
    };

    return customClusterMarkerIconHook;
  }

Note: If you want to show the Default Cluster Marker Icon, return null.

Added in version 1.3.8
