onDragEnd not fired on apple maps

[yspreen]

Describe the bug
On apple maps, onDragEnd is not fired. I tried consumeTapEvents true and false, no change.

To Reproduce

        Marker(
          markerId: MarkerId('marker_${e.uuid}'),
          position: e.position.latLng,
          draggable: true,
          onDragEnd: _mapTap,
          // consumeTapEvents: true,
        ),

1. hold down marker
2. move it around
3. let go
4. event is not fired

Expected behavior
_mapTap should be called but isnt

Hello! I'm actually using this feature, and I can confirm that is not working correctly on iOS. Is there something I can do to help you with this issue? I'd like to contribute to this repo, if possible.
