childReactiveState

fun <E : ErrorEvents, P : ReactiveState<out E>, RS : ReactiveState<E>> P.childReactiveState(block: () -> RS): ReadOnlyProperty<Any?, RS>

Creates and attaches a child ReactiveState.

This merges the child's ReactiveState.eventNotifier and ReactiveState.loading into the parent.

Example:

// The parent has to also implement the child events
interface ParentEvents : ChildEvents {
    fun onSomeEvent()
}

class ParentViewModel(scope: CoroutineScope) : BaseReactiveState<ParentEvents>(scope) {
    val childViewModel by childReactiveState { ChildViewModel(scope) }
}

interface ChildEvents : ErrorEvents {
    fun onSomeChildEvent()
}

class ChildViewModel(scope: CoroutineScope) : BaseReactiveState<ChildEvents>(scope) {
    init {
        launch {
            // ...
            eventNotifier {
                onSomeChildEvent()
            }
        }
    }
}
