Case 1. When the Snackbar is visible, and user triggers showFABMenu(), the small FABs will all overlapped together at the bottom of the screen after the Snackbar is dismissed.

Case 2. When the FABMenu is visible, and then the Snackbar is shown, the MoveUpwardBehavior correctly "pushes" the big FAB upwards, but the small FABs aren't moving.

Any idea to fix this? I'm not too familiar with the animation of this kind. Thank you!

there is a bug in the rotation of the main FAB. the bug is not apparent in the current demo because the graphic (ic_toys) is symmetrical. if you replace the graphic with one that is not symmetrical (for example, if you replace ic_toys with ic_mic) then you get the bug - the graphic ends up upside down after the animation.

edit: after running this in the debugger, it appears to me that showFABMenu() sometimes triggers the listener in closeFABMenu(), and vice versa. so the rotation set by one of those functions may get superseded by the rotation set by the other, leaving the FAB in an incorrect position. this is under API 28.
