NavBackStackEntry

Kotlin |Java

public final class NavBackStackEntry
extends Object implements LifecycleOwner, ViewModelStoreOwner, HasDefaultViewModelProviderFactory, SavedStateRegistryOwner

java.lang.Object
↳	androidx.navigation.NavBackStackEntry

Representation of an entry in the back stack of a NavController. The Lifecycle, ViewModelStore, and SavedStateRegistry provided via this object are valid for the lifetime of this destination on the back stack: when this destination is popped off the back stack, the lifecycle will be destroyed, state will no longer be saved, and ViewModels will be cleared.
