Hilt NavigationDispatcher

NavigationDispatcher.kt

@ActivityRetainedScoped
class NavigationDispatcher @Inject constructor() {
    private val navigationEmitter: EventEmitter<NavigationCommand> = EventEmitter()
    val navigationCommands: EventSource<NavigationCommand> = navigationEmitter

    fun emit(navigationCommand: NavigationCommand) {
        navigationEmitter.emit(navigationCommand)
    }
}

The idea of this sample is to use it in viewmodel to navigate, something like this
navigationDispatcher.emit { navController -> navController.navigateUp() }
for example. How to use result API and return something when fragment is required and there is no way to get fragment from navController? Did you have a need for this? I ended up using an older API something like
previousBackStackEntry?.savedStateHandle?.set(key, result)
