Public functions

createDestination

Added in 2.1.0

open fun createDestination(): DialogFragmentNavigator.Destination

Construct a new NavDestination associated with this Navigator.

Any initialization of the destination should be done in the destination's constructor as it is not guaranteed that every destination will be created through this method.

Returns
DialogFragmentNavigator.Destination	a new NavDestination

navigate

open fun navigate(
    entries: List<NavBackStackEntry>,
    navOptions: NavOptions?,
    navigatorExtras: Navigator.Extras?
): Unit

Navigate to a destination.

Requests navigation to a given destination associated with this navigator in the navigation graph. This method generally should not be called directly; NavController will delegate to it when appropriate.

Parameters
entries: List<NavBackStackEntry>	destination(s) to navigate to
navOptions: NavOptions?	additional options for navigation
navigatorExtras: Navigator.Extras?	extras unique to your Navigator.

onAttach

open fun onAttach(state: NavigatorState): Unit

Indicator that this Navigator is actively being used by a NavController. This is called when the NavController's state is ready to be restored.

onLaunchSingleTop

open fun onLaunchSingleTop(backStackEntry: NavBackStackEntry): Unit

Informational callback indicating that the given backStackEntry has been affected by a NavOptions.shouldLaunchSingleTop operation. The entry provided is a new NavBackStackEntry instance with all the previous state of the old entry and possibly new arguments.

popBackStack

open fun popBackStack(popUpTo: NavBackStackEntry, savedState: Boolean): Unit

Attempt to pop this navigator's back stack, performing the appropriate navigation.

All destinations back to popUpTo should be popped off the back stack.

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.
