If you want to use view binding for MapFragment's ID as mentioned in the quoted bounty message below:

How to use View binding in SupportMapFragment' ID?

What you can do is simply write

val mapFragment = childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment

as

val mapFragment = childFragmentManager.findFragmentById(binding.map.id) as SupportMapFragment

This will prevent it from being null which is the case you want.
