onWaypointArrival
Triggered when the RouteProgress.currentState is equal to RouteProgressState.COMPLETE, once per route leg, and when there are more route legs to navigate. If we're on the last leg of the route onFinalDestinationArrival is called instead. If you want to provide different experiences for arriving at different types of waypoints (e. g. regular or EV), you can look up the waypoint type via RouteLegProgress.legDestination.
