In my radio app there will be FloatingActionButton to play.
What I would very much like to implement in this Button is the animation of the play icon turning into the stop icon, more or less as shown here .
I searched for a lib for this but could not find it, also because I'm not sure if this is inherent in the lib that is responsible for FAB or is relative only to the image that is shown in FAB .
Does anyone know how to implement this functionality?
