          initConfig: BooksListNavigate.routeConfig,
          configs: [
            // pages
            BookDetailsNavigate.routeConfig,
            BooksListNavigate.routeConfig,

  @override
  RouteState get currentConfiguration {
    return currentState;
  }

  // helper
  static NavmeRouterDelegate of(BuildContext context) {
    final delegate = Router.of(context).routerDelegate;
    if (delegate is NavmeRouterDelegate) {
      return delegate;
    }
    assert(() {
      throw FlutterError('Router operation requested with a context that does not include a NavmeRouterDelegate.\n');
    }(), 'Router operation requested with a context that does not include a NavmeRouterDelegate.\n');
    return null;
  }

  @override
  Widget build(BuildContext context) {
    return Navigator(
      key: navigatorKey,
      observers: [HeroController()], // THIS IS THE IMPORTANT LINE for Hero
      pages: buildPage(), // your stack pages
      onPopPage: (route, result) {
        if (!route.didPop(result)) {
          return false;
        }
        pop();
        return true;
      },
