Is there a proper way to observe a SharedFlow in a Composable function, for StateFlow we'd use collectAsState but if I do that for a SharedFlow, it will remember the last value, instead of firing and forget

Can you describe your use case?

[Micko Cabacungan]

Basically I am trying to send a one time SideEffect that will play an animation

[Micko Cabacungan]

but I want to be able to do this everytime I send that SideEffect to play the animation

[Chris Fillmore]

Someone may have a better answer, but you can collect the SharedFlow in a LaunchedEffect, then do what you will as new values come in

I have some similar-sounding requirement in my backlog currently so I’d be curious to know how this turns out for you

I will give you an update if it works out 👍

Had a similiar issue for navigation event. Found that extensionfunction on the web (can't remember where) and it works just fine.

@Composable
fun <T> Flow<T>.collectAsEffect(
    context: CoroutineContext = EmptyCoroutineContext,
    block: (T) -> Unit,
) {
    LaunchedEffect(key1 = Unit) {
        onEach(block).flowOn(context).launchIn(this)
    }
}

@Chris Fillmore ^ -- I had a work around but this seems to be much cleaner

Thank you @Tobias Gronbach
