didPop method

@override void didPop(Route route, Route? previousRoute)

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) {
  _poppedRoutes.add(_history.last);
  _history.removeLast();
  _historyChangeStreamController.add(HistoryChange(
    action: NavigationStackAction.pop,
    newRoute: route,
    oldRoute: previousRoute,
  ));
}
