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