is very low level. It is not an API for simple use cases. You could use it for cases where you manipulate the animation time, such as pause/resume an animation, manage an animation's interruption, etc. If you are interested in seeing how it's used, you can find it as a building block for a lot of the higher level APIs such as Transition, Animatable, etc. See: https://developer.android.com/images/jetpack/compose/animation-low-level.svg
