Different behavior [Enhancement]

[AkshayChordiya]

Hi @truizlop

Thank you for such an amazing library. I was thinking of a different implementation / behavior.
In which the FAB would be at right button when clicked it would come at the center of the screen and then perform the reveal animation to cover complete screen. The covering screen can have a secondary layout.
I know this is difficult to understand. I'll try to get some visuals if possible.
