Summary

Public methods
static OnClickListener	`createNavigateOnClickListener(@IdRes resId: Int)` Create an `android.view.View.OnClickListener` for navigating to a destination.
static OnClickListener	`createNavigateOnClickListener(@IdRes resId: Int, @Nullable args: Bundle?)` Create an `android.view.View.OnClickListener` for navigating to a destination.
static OnClickListener	`createNavigateOnClickListener(@NonNull directions: NavDirections)` Create an `android.view.View.OnClickListener` for navigating to a destination via a generated `NavDirections`.
static NavController	`findNavController(@NonNull activity: Activity, @IdRes viewId: Int)` Find a `NavController` given the id of a View and its containing `Activity`.
static NavController	`findNavController(@NonNull view: View)` Find a `NavController` given a local `View`.
static Unit	`setViewNavController(@NonNull view: View, @Nullable controller: NavController?)` Associates a NavController with the given View, allowing developers to use `findNavController(View)` and `findNavController(Activity, int)` with that View or any of its children to retrieve the NavController.
