`OnBackCompletedFallback`	A listener that provides a final fallback action for unhandled `backCompleted` callbacks.

Classes

`DirectNavigationEventInput`	An input that can send events to a `NavigationEventDispatcher`.
`NavigationEvent`	Represents a system navigation event, such as a predictive back gesture or a back button press.
`NavigationEventDispatcher`	A dispatcher for navigation events that can be organized hierarchically.
`NavigationEventHandler`	Base class for handling navigation gestures dispatched by a `NavigationEventDispatcher`.
`NavigationEventHistory`	Represents an immutable snapshot of the navigation history stack.
`NavigationEventInfo`	Provides contextual information about a navigation state (e.g., a screen or route).
`NavigationEventInput`	An abstract class for components that generate and dispatch navigation events.
`NavigationEventTransitionState`	Represents the physical state of a navigation gesture, such as a predictive back or forward swipe.
`NavigationEventTransitionState.InProgress`	Represents the state where a navigation gesture is actively in progress.
`OnBackInvokedDefaultInput`	Provides input to a `NavigationEventDispatcher` by registering an `OnBackInvokedCallback` with the `OnBackInvokedDispatcher.PRIORITY_DEFAULT` priority to `onBackInvokedDispatcher`.
`OnBackInvokedInput`	Provides input to a `NavigationEventDispatcher` by registering an `OnBackInvokedCallback` to the passed in `onBackInvokedDispatcher`.
`OnBackInvokedOverlayInput`	Provides input to a `NavigationEventDispatcher` by registering an `OnBackInvokedCallback` with the `OnBackInvokedDispatcher.PRIORITY_OVERLAY` priority to `onBackInvokedDispatcher`.
