Returns
DialogNavigator.Destination	a new NavDestination

    entries: List<NavBackStackEntry>,
    navOptions: NavOptions?,

Parameters
popUpTo: NavBackStackEntry	the entry that should be popped off the NavigatorState.backStack along with all entries above this entry.
savedState: Boolean	whether any Navigator specific state associated with popUpTo should be saved to later be restored by a call to navigate with NavOptions.shouldRestoreState.
