MotionLayout: MotionLayout.TransitionListener onTransitionTrigger not be triggered.

[TakumaLee]

I found the function fireTrigger in MotionLayout but this function not like onTransitionStarted, onTransitionChange and onTransitionCompleted will be call.

And in my case, I need this lifecycle or another method to do my feature. Like click a FloatingActionButton, and I change the image with vector svg and animation.
