collectAsState

@Composable
fun <T : R, R : Any?> Flow<T>.collectAsState(
    initial: R,
    context: CoroutineContext = EmptyCoroutineContext,
    mutationPolicy: SnapshotMutationPolicy<R> = structuralEqualityPolicy()
): State<R>

Collects values from this Flow and represents its latest value via State. Every time there would be new value posted into the Flow the returned State will be updated causing recomposition of every State.value usage.

Optionally, the context that the flow is collected in and the mutationPolicy that is used to report and merge changes in the returned state can be customized. If the context or Flow changes, the same state will be returned, the previous collection will be canceled, and the provided Flow will start collection in the new context. Changes to the mutationPolicy after the state has been created are ignored.
