Hi and welcome to the forum! 
I would suggest you check the documentation on how to go about creating components using UX. This video on Triggers and Animators is also a good place to start to learn how to style elements that respond to user input (like the FAB button in Material Design): https://www.youtube.com/watch?v=bT1npBvXEzw
