@shubham7109 - implementation looks good, nice work. I did some ad-hoc testing and noticed that the app crashes/freezes every time I rotate the screen. Could you test this on your end.

@gunt0001 Nice catch, took me some thinking to unravel the behavior:

noticed that the app crashes/freezes every time I rotate the screen

Turns out the OrbitGeoElementCameraController will trigger a crash if the geoElement the controller is orbiting is not part of the visible graphics overlay of the SceneView. On rotation, previous graphics overlay containing the plane graphic is replaced with a new one, which causes the controller to trigger a crash.

Added some improvements to dispose of the old controller, and create a new controller for each lifecycle keeping the graphic overlay displayed up-to-date with the orbit controller provided to the SceneView. (Using GlobeCameraController as the default fallback.)
