Nobody has claimed this yet.

version: mapbox_maps_flutter 0.5.0

Steps to reproduce:
```
Future _onMapCreated(MapboxMap mapboxMap) async {
this.mapboxMap = mapboxMap;

mapboxMap.subscribe(_onMapEvent, [
MapEvents.RESOURCE_REQUEST,

Start in mapbox_maps_platform.dart around the switch at line 50 and the MissingPluginException reported at line 104. Reproduce the MapEvents.RESOURCE_REQUEST subscription from the issue, then verify that the event no longer throws and is handled consistently with the other event types.
