  interface SupportingPane

*** ** * ** ***

A marker interface for `https://developer.android.com/reference/kotlin/androidx/navigation/NavDestination` subclasses that sit alongside the view of other destinations.

Supporting pane destinations have the same lifecycle as the other visible destinations (e.g., a non-SupportingPane destination will continue to be resumed when a supporting pane is added to the back stack).

`https://developer.android.com/reference/kotlin/androidx/navigation/NavController.OnDestinationChangedListener` instances can also customize their behavior based on whether the destination is a SupportingPane.
