gamelist是集合中文档名称的字符串列表。questionMap值是一个名为"text"字段的数组，该数组是使用gamelist值作为键从firestore文档中获得的。我希望在按下pass按钮时更新questionMap。当我按下pass按钮时，我看到questionMap确实在我打印此代码时更新，但是屏幕没有重新绘制，我得到了标题中显示的错误。这是一个脏代码，但我想知道如何解决它。
这是我的代码：

class PlayPage extends StatefulWidget {
  List gameList;
  Map questionMap;
  String category;
  int myScore;

  PlayPage({
    required this.gameList,
    required this.category,
    required this.myScore,
    required this.questionMap,
  });

  @override
  State<PlayPage> createState() => _PlayPageState();
}

class _PlayPageState extends State<PlayPage> {
  int quizNumber = 0;
  int listNumber = 0;
  var db = FirebaseFirestore.instance;

  void changeQuiz() {
    super.didChangeDependencies();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Stack(
        children: [
          Card(
            child: SizedBox(
              height: double.infinity,
              child: SingleChildScrollView(
                child: Padding(
                  padding: const EdgeInsets.only(
                      top: 20, bottom: 200, left: 20, right: 20),
                  child: Text(
                    widget.questionMap[widget.gameList[listNumber]][quizNumber],
                    style: const TextStyle(fontSize: 20),
                  ),
                ),
              ),
            ),
          ),
          Positioned(
            right: 10,
            bottom: 30,
            child: Column(
              children: [
                ElevatedButton(
                  child: const Text(
                    "Pass",
                    style: TextStyle(fontSize: 30),
                  ),
                  onPressed: () {
                    listNumber += 1;
                    quizNumber = 0;
                    setState(
                      () {
                        var docRef = db
                            .collection(widget.category)
                            .doc(widget.gameList[listNumber]);
                        docRef.get().then(

                            widget.questionMap = {

                            };
                            print(widget.questionMap);
                          },
                        );
                      },
