didPop method
The Navigator popped route.
The route immediately below that one, and thus the newly active
route, is previousRoute.
Implementation
@override
void didPop(s.Route<dynamic> route, s.Route<dynamic>? previousRoute) {
debugPrint(
'AxCustomRouteObserver: didPop called for route ${route.settings.name ?? route.runtimeType}');
super.didPop(route, previousRoute);
}
