Should `MarkerViewManager` implement a more 'reactive' camera listener ?

Hello,
The MarkerViewManager implements the MapView.OnCameraDidChangeListener so updating a MarkerView is only updated after the camera did change, and not while the camera is changing.

The consequence of that is some sluggish MarkerView re-positioning after a camera move, as shown here:

I tried replacing MapView.OnCameraDidChangeListener by MapView.OnCameraIsChangeingListener and had no more updates ?!

I then tried using MapboxMap.OnCameraMoveListener with better results:

GPU usage is a tad high, that's why I'm not sending a PR.

Should MarkerViewManager implements a more 'reactive' camera listener ?

PS: on the above gifs, I'm using react-native with:

• https://github.com/react-native-mapbox-gl/maps
• and https://github.com/react-native-community/lottie-react-native for the animated orange markers

Commencez par localiser MarkerViewManager et son implémentation de MapView.OnCameraDidChangeListener, puis comparez son comportement à celui des listeners de caméra mentionnés dans le rapport. Reproduisez le repositionnement saccadé des marqueurs avec la configuration React Native et Lottie liée ; c’est terminé lorsque les mises à jour sont plus fluides sans coût GPU inacceptable.
