public class MutableTransitionState<S>(initialState: S) : TransitionState<S>()MutableTransitionState contains two fields: currentState and targetState. currentState is initialized to the provided initialState, and can only be mutated by a Transition. targetState is also initialized to initialState. It can be mutated to alter the course of a transition animation that is created with the MutableTransitionState using rememberTransition. Both currentState and targetState are backed by a State object.
