Steps to reproduce

When working with cluster manager pins on Android, the pin info window's onTap callback doesn't fire.

To reproduce the issue, use the example project in the flutter packages repo, under packages/google_maps_flutter/google_maps_flutter/example/. Edit lib/clustering.dart to add an onTap to the InfoWindow in _addMarkersToCluster(), around line 171:

        infoWindow: InfoWindow(
          title: markerIdVal,
          snippet: '*',
          onTap: () {
            debugPrint('Info window of $markerIdVal was tapped'); // or any other action
          },
        ),

After making the above edit:

1. Run the example app in debug mode
2. Click the "Manage clustering" option
3. Click "Add cluster manager"
4. Zoom in until you can see the pins
5. Tap on a pin
6. Tap on the pin info window

Note that in Android, nothing happens, but in iOS, the callback fires, so the debug print occurs.

Expected results

The cluster pin marker info window onTap callback should fire for Android just like it fires for other platforms.

Actual results

The cluster pin marker info window onTap callback fires for other platforms, but not for Android.
