API v2 with turf conflicts with internal Mapbox classes

I have migrated from v1 to v2 and now I have class mismatch errors all over the place.

Look like Mapbox sdk is having it's own Point class that extends turf Point. Which is fine I guess.

But the issue is that if I use FeatureCollection.fromJson(jsonDecode(data) as Map<String, dynamic>); as FeatureCollection is not a class from Mapbox but from (geotype but let's say turf) then when I try to to pass this featureCollection back to Mapbox is fails with the following error:

type 'Point' is not a subtype of type 'Point' in type cast where
  Point is from package:geotypes/src/geojson.dart
  Point is from package:mapbox_maps_flutter/mapbox_maps_flutter.dart

v2 is currently not usable to me.

Start with the v1-to-v2 migration context and reproduce the failure using FeatureCollection.fromJson(jsonDecode(data) as Map<String, dynamic>). Trace the two Point types shown in the error across geotypes and mapbox_maps_flutter, and consider the issue done when a decoded FeatureCollection can be passed back to Mapbox without the type-cast conflict.
