didPop method

  1. @override
void didPop (Route route, Route previousRoute)
override

The Navigator popped route.

The route immediately below that one, and thus the newly active route, is previousRoute.

Implementation 

@override
void didPop(Route<dynamic> route, Route<dynamic> previousRoute) {
  if (route is R && previousRoute is R) {
    final List<RouteAware> previousSubscribers = _listeners[previousRoute]?.toList();

    if (previousSubscribers != null) {
      for (RouteAware routeAware in previousSubscribers) {
        routeAware.didPopNext();
      }
    }

    final List<RouteAware> subscribers = _listeners[route]?.toList();

    if (subscribers != null) {
      for (RouteAware routeAware in subscribers) {
        routeAware.didPop();
      }
    }
  }
}
