我尝试将CupertinoTabBar与命名路线一起使用。我尝试添加一个CupertinoTabScaffold，并在标签栏中显示标签视图，但当应用将应用推送到不同的路线时，应用抛出错误：
FlutterError（无法在_CupertinoTabViewState中找到路径RouteSettings（“/randomONE”，空）的生成器

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider(
      create: (context) => SomeProvider(),
      child: MaterialApp(
        title: 'Cool Title',
        home: CupertinoTabScaffold(
            tabBar: CupertinoTabBar(
              items: [
                BottomNavigationBarItem(title: Text('First Page'), icon: Icon(Icons.access_alarms)),

                BottomNavigationBarItem(title: Text('Third Page'), icon: Icon(Icons.accessible)),
