Is something wrong with my state machine? about statemachine

Hi @Shrikant-B,

By looking at your code, I can see you're posting transition.fromState to the MutableLiveData. That means it would never emit the terminal states you defined (Success or Failure) unless you postValue the toState part of the transition instead.

Also, you're not actually posting the initial state (Loading) as the ViewModel gets initialized.
I hope this helps.

@lfernandosp Thanks for you suggestion, it did helped me with my issue.
So, I changed my LiveData from MutableLiveData<State> to MutableLiveData<StateMachine.Transition<State, Event, SideEffect>>() that gives me Transition with ToState & SideEffect.

I have statemachine as below:

val stateMachine = StateMachine.create<State, Event, SideEffect> {
        initialState(State.Idle)
        state<State.Idle> { onEnter { dontTransition(SideEffect.OnIdle) } }
        onTransition {
            if (it is StateMachine.Transition.Valid) {
                when (it.sideEffect) {
                    is SideEffect.OnIdle -> {

                    }
                }
            } else {
                Log.e("StateMachine", "Invalid transition")
            }
        }
    }

As stateMachine.transition() requires Event to get Transition. How do I consume Transition from onEnter dontTransition?
