Hello folks! Quick shout out to the team for the library. We are on a compose re-write in our org for our user facing app and we decided to use Orbit-MVI after much deliberation. We've been loving it so far. Quick questions to the team : 1. Will there be a support for

collectAsStateWithLifecycle

method while consuming state? This was introduced as a part of

androidx.lifecycle:lifecycle-runtime-compose:2.6.0-alpha01

collectAsStateWithLifecycle

uses

repeatOnLifecycle

under the hood. Reference : https://medium.com/androiddevelopers/consuming-flows-safely-in-jetpack-compose-cde014d0d5a3

not a team member, but we also use orbit + compose, so end up with own extension

Copy code

/**
 * Collect [ContainerHost.container]'s state via [collectAsState] but bounded with the [flowWithLifecycle]
 */
@Composable
fun <STATE : Any, SIDE_EFFECT : Any> ContainerHost<STATE, SIDE_EFFECT>.composableState(
    minActiveState: Lifecycle.State = Lifecycle.State.STARTED
): State<STATE> {
    val lifecycleOwner = LocalLifecycleOwner.current
    val lifecycleAwareStateFlow = remember(this, lifecycleOwner) {
        container.stateFlow.flowWithLifecycle(lifecycleOwner.lifecycle, minActiveState)
    }
    return lifecycleAwareStateFlow.collectAsState(currentState)
}

Yep, there's nothing stopping you from using these APIs yourself - we expose `Flow`s on the container after all.

We'll probably update our own compose extensions to use this under the hood soon

@Oleksii Malovanyi I believe this is already there if you're calling
