I'm trying to use `MutableStateFlow` for the first...

I'm trying to use MutableStateFlow for the first time, but it is not doing what I expect

private val state = MutableStateFlow<MyState>(INITIAL_STATE)

suspend fun refresh(): MyState {
  val newState = service.refresState()
  this.state.value = newState
  return newState
}

fun observeState(): Flow<MyState> {
  return state
    .transform { s ->
        if (s !== INITIAL_STATE) {
            emit(s)
        } else {
            refresh() // expecting this to automatically send a new state to the flow
        }
    }
}

I was expecing the refresh() to cause a new state to be emitted, but it didn't.

Can someone guide me in the right direction?
thanks.

is it an actual new object? StateFlow will only emit if it has a new (non-equal) object

If my memory serves me right

oh, I didn't know it had a comparison in it, let me try changing it a bit

ah! it was clearly stated in the doc, I missed it, thanks
