Hello again, I almost study each GitHub KMM sample your's is the best. I have a question if you plz. 

  private val _event: MutableSharedFlow<Event> = MutableSharedFlow()
    val event = _event.asSharedFlow()

    private val _effect: Channel<Effect> = Channel()
    val effect = _effect.receiveAsFlow()

what is the clear difference between effects and events? and why events are MutableSharedFlow where _effect is Channel

Hi!

Thank you so much!!

Event are UI action to ViewModel. UI -> ViewModel Effect are single shot event from ViewModel to UI (don't have state) like show toast, show snack bar, show dialog or navigation action.

MVI pattern is based in this great article: https://proandroiddev.com/mvi-architecture-with-kotlin-flows-and-channels-d36820b2028d
