FragmentNavigator

open class FragmentNavigator : Navigator<FragmentNavigator.Destination!>
kotlin.Any
   ↳ androidx.navigation.Navigator<androidx.navigation.fragment.FragmentNavigator.Destination>
   ↳ androidx.navigation.fragment.FragmentNavigator

Navigator that navigates through fragment transactions. Every destination using this Navigator must set a valid Fragment class name with android:name or Destination#setClassName(String).

The current Fragment from FragmentNavigator's perspective can be retrieved by calling FragmentManager#getPrimaryNavigationFragment() with the FragmentManager passed to this FragmentNavigator.

Note that the default implementation does Fragment transactions asynchronously, so the current Fragment will not be available immediately (i.e., in callbacks to NavController.OnDestinationChangedListener).

Deprecated: Set a custom androidx.fragment.app.FragmentFactory via FragmentManager#setFragmentFactory(FragmentFactory) to control instantiation of Fragments.
