FloatingActionBarMenuButton<T> class
A circular trailing action that expands into a popup menu.
This is the menu counterpart to FloatingActionBarActionButton. It reuses the same circular surface style, but opens a popup menu built from items and reports the selected item's value through onSelected.
Multiple action buttons and menu buttons can be mixed in FloatingActionBar.actions.
