popRoute method

  1. @override
Future<bool> popRoute()
override

Called by the Router when the Router.backButtonDispatcher reports that the operating system is requesting that the current route be popped.

The method should return a boolean Future to indicate whether this delegate handles the request. Returning false will cause the entire app to be popped.

Consider using a SynchronousFuture if the result can be computed synchronously, so that the Router does not need to wait for the next microtask to schedule a build.

Implementation

@override
Future<bool> popRoute() {
  final NavigatorState? navigator = navigatorKey?.currentState;
  return navigator?.maybePop() ?? SynchronousFuture<bool>(false);
}
