Add an API to get the fragment that was most recently added
to a FragmentContainerView
Adding an API to get the fragment that was most recently added
to the calling FragmentContainerView. This allows users to get the
fragment directly from the FragmentContainerView, instead of having
to go through the FragmentManager.
RelNote: "`FragmentContainerView` now provides `getFragment()`,
which returns the fragment that was most recently added to the container."

This has been added internally and will be available in the upcoming Fragment 1.4.0-alpha01 release.
Description
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 asfindViewById()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
FragmentContainerViewinstance, but not necessarily to itsR.idto pass intofindFragmentById().With this, you could then write code such as:
