One-off events

[ATizik]

In google samples certain events are propagated through SingleLiveEvent.

While this concept goes against MVI principle, it's needed in certain cases to greatly reduce boilerplate. For example, to show toast in current implementation I have to create a property inside my state, and inside View send an event back to ViewModel telling it that toast was shown.

Another similar solution can be used in every ViewModel to fire such one-off events.

Second example can be easily done through an additional subject inside MvRxStateStore and subscription inside withState

@ATizik We use selectSubscribe for this. You will be delivered the initial value and any time it changes. We also have asyncSubscribe if it's an async prop to handle the unwrapped success or error values.

We use these to handle things like logging or showing toasts/snackbars.

If this isn't sufficient, can you reopen this with a specific use case?
