Component used: Fragment

Version used: 1.3.0-alpha07

It would be nice to have a way to retrieve the topmost fragment (i.e., the last added fragment) from a FragmentContainerView, particularly if it used the same technique as findViewById() to cast the Fragment to the right type.

This would be particularly helpful when using View Binding or Data Binding where you have easy access to the FragmentContainerView instance, but not necessarily to its R.id to pass into findFragmentById().

With this, you could then write code such as:

val navHostFragment: NavHostFragment = binding.container.getFragment()

// Or chain the call
val navController = binding.container.getFragment<NavHostFragment>().navController
