How to combine BottomAppBar + FAB with BottomNavigationView

Question

I want to use the FloatingActionButton, along with its behaviour when anchored on a BottomAppBar, on top of a BottomNavigationView.

Well you can treat BottomAppBar as Toolbar, which means that, this class extends ViewGroup so you can add relative layout, constraint layout etc inside BottomAppBar tag. Here is fragment of code that will show 2 buttons inside BottomAppBar.
