Flutter:如何在使用popUntil导航到页面时更新页面

class MyPage extends StatefulWidget {
  @override
  _MyPageState createState() => _MyPageState();
}

class _MyPageState extends State<MyPage> {
  String data = 'Initial data'; // 需要更新的数据

  // ...
}

Navigator.popUntil(context, ModalRoute.withName('/targetPage'), arguments: 'Updated data');

class TargetPage extends StatefulWidget {
  @override
  _TargetPageState createState() => _TargetPageState();
}

class _TargetPageState extends State<TargetPage> {
  String data;

  @override
  void initState() {
    super.initState();
    data = ModalRoute.of(context).settings.arguments as String; // 获取传递过来的参数
  }

  // ...

  // 在需要更新页面时调用setState方法
  void updatePage() {
    setState(() {
      data = 'Updated data';
    });
  }
}
