Is there a nice way to convert a shared flow to a state flow by just providing the initial value? The flow is already hot, so I'm hoping I wouldn't need to provide a scope (and wouldn't have a separate collection coroutine running)

[rnett]

The closest I can find is MutableStateFlow().onCompletion{ emitAll(sharedFlow) } which loses the state flow type

[Geert]

Do you mean something like: sharedFlow.stateIn(someCoroutineScope) ?

[rnett]

Kind of, but I want to provide the initial value, and ideally not have collection running in another coroutine

How would you imagine it would work behind the scenes?

You could provide your own implementation of the StateFlow interface:

public interface StateFlow<out T> : SharedFlow<T> {
    /**
     * The current value of this state flow.
     */
    public val value: T
}

But it’s hard to get right. If look at google for implementations of `fun StateFlow.map(…):StateFlow`you will probably find some inspiration

I realized that the constantly up to date value accessor was driving most of the problems, and I didn't actually need it (I just needed the initial value to pass into collectAsState, so I went with that and just passed around the initial value and flow of updates
