NavigationRouteTrackingStateUpdateObserver

public protocol NavigationRouteTrackingStateUpdateObserver : Observer

An observer to receive route tracking state updates.

The information about the route state is represented by RouteTrackingState. When the driver deviates or returns to the active route, the navigation engine sends route-tracking state updates to the observer.

To start receiving route tracking state updates, become an observer using Navigation.addRouteTrackingStateUpdateObserver(_ observer:): To stop receiving route tracking state updates, remove the previously added observer using Navigation.removeRouteTrackingStateUpdateObserver(_ observer:):
