Is there an extension on lifecycle that provides a

flow

for lifecycle state changes?

There’s not one that I could find, but I wrote this a while back.

channelFlow {
    val listener = LifecycleEventObserver { _, event ->
        when (event) {
            Lifecycle.Event.ON_RESUME -> trySend(PlatformLifecycle.State.Started)
            Lifecycle.Event.ON_PAUSE -> trySend(PlatformLifecycle.State.Stopped)
            else -> Unit
        }
    }

    delegate.lifecycle.addObserver(listener)
    awaitClose { delegate.lifecycle.removeObserver(listener) }
}.stateIn(coroutineScope, SharingStarted.Eagerly, initialValue = PlatformLifecycle.State.Stopped)

I wrote something similar. Was hoping there would be something in androidx but ¯\_(ツ)_/¯

Feel free to star the feature request: https://issuetracker.google.com/issues/176311030

Don't you mean 😛lus1:

Would be nice to expose this as a stateflow (if it’s implemented) since the lifecycle represents the current state of something
