Extension functions

inline fun <F : DialogFragment> NavGraphBuilder.dialog(id: @IdRes Int): Unit

Construct a new DialogFragmentNavigator.Destination

Parameters
id: @IdRes Int

the destination's unique id

inline fun <F : DialogFragment> NavGraphBuilder.dialog(route: String): Unit

Construct a new DialogFragmentNavigator.Destination

Parameters
route: String

the destination's unique route

inline fun <F : DialogFragment> NavGraphBuilder.dialog(
    id: @IdRes Int,
    builder: DialogFragmentNavigatorDestinationBuilder.() -> Unit
): Unit

Construct a new DialogFragmentNavigator.Destination

Parameters
id: @IdRes Int

the destination's unique id

builder: DialogFragmentNavigatorDestinationBuilder.() -> Unit

the builder used to construct the fragment destination

inline fun <F : DialogFragment> NavGraphBuilder.dialog(
    route: String,
    builder: DialogFragmentNavigatorDestinationBuilder.() -> Unit
): Unit

Construct a new DialogFragmentNavigator.Destination

Parameters
route: String

the destination's unique route

builder: DialogFragmentNavigatorDestinationBuilder.() -> Unit

the builder used to construct the fragment destination

findNavController

fun Fragment.findNavController(): NavController

Find a NavController given a Fragment

Calling this on a Fragment that is not a NavHostFragment or within a NavHostFragment will result in an IllegalStateException

inline fun <F : Fragment> NavGraphBuilder.fragment(id: @IdRes Int): Unit

Construct a new FragmentNavigator.Destination

Parameters
id: @IdRes Int

the destination's unique id

inline fun <F : Fragment> NavGraphBuilder.fragment(route: String): Unit

Construct a new FragmentNavigator.Destination

Parameters
route: String

the destination's unique route

inline fun <F : Fragment> NavGraphBuilder.fragment(id: @IdRes Int, builder: FragmentNavigatorDestinationBuilder.() -> Unit): Unit

Construct a new FragmentNavigator.Destination

Parameters
id: @IdRes Int

the destination's unique id

builder: FragmentNavigatorDestinationBuilder.() -> Unit

the builder used to construct the fragment destination

inline fun <F : Fragment> NavGraphBuilder.fragment(route: String, builder: FragmentNavigatorDestinationBuilder.() -> Unit): Unit

Construct a new FragmentNavigator.Destination

Parameters
route: String

the destination's unique route

builder: FragmentNavigatorDestinationBuilder.() -> Unit

the builder used to construct the fragment destination

@MainThread
inline fun <Args : NavArgs> Fragment.navArgs(): NavArgsLazy<Args>

Returns a Lazy delegate to access the Fragment's arguments as an Args instance.

It is strongly recommended that this method only be used when the Fragment is created by androidx.navigation.NavController.navigate with the corresponding androidx.navigation.NavDirections object, which ensures that the required arguments are present.

class MyFragment : Fragment() {
val args: MyFragmentArgs by navArgs()
}

This property can be accessed only after the Fragment's constructor.
