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() {
  _controller.removePoppedPageIfNotUserInitiated(null);

  // Always return true to indicate we handled the pop request
  // This prevents the app from closing on Android
  return SynchronousFuture(true);
}
