I was using this simple code till 1.6.0-RC, but in 1.6.0-RC2 it's not working anymore because the collect extension function was removed with https://github.com/Kotlin/kotlinx.coroutines/pull/3047 :

val stateFlow = MutableStateFlow(State())
        val actionFlow = MutableSharedFlow<Action>()
        launch {
            actionFlow.collect {
                stateFlow.value = stateReducer(stateFlow.value, it)
            }
        }

What is the correct way to implement this?

This seems to work:

launch {
            actionFlow.onEach {
                stateFlow.value = stateReducer(stateFlow.value, it)
            }.collect()
        }

Removing not deprecated, public functions should be more clearly marked as a breaking change in the changelog.

There is a bug for this there. It looks like a commit just went into develop that is removing the @InternalCoroutinesApi on the actual Flow.collect, which I think should allow old source code to compile as-is

It's a RC version and this bug was not intentional, the annotation was not removed.

Thanks for info!
