popRoute method

@override Future<bool> popRoute()

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() {
  // TODO: implement this
  // if (navigationNotifier.canPop()) {
  //   navigationNotifier.popPage();
  //   return Future.microtask(() => true);
  // } else {
  return Future.microtask(() => false);
  // }
}
