liveObject.observeAsState()

State<T>

Note: observeAsState observes a LiveData<T> and returns a State<T> object that is updated whenever the LiveData changes. State<T> is an observable type that Jetpack Compose can use directly.

observeAsState will observe the LiveData only while it is in the Composition.

@Composable
fun <R, T : R> LiveData<T>.observeAsState(initial: R): State<R> {
    val lifecycleOwner = LifecycleOwnerAmbient.current
    val observer = remember { DisposableObserver<R, T>(initial, lifecycleOwner) }
    observer.source = this
    return observer.state
}

liveData.observe(this) { recompose() }

val unregisterApplyObserver = Snapshot.registerApplyObserver { changed, _ ->
    appliedChanges.offer(changed)
}
