到目前为止，我已经在这个问题上被困了4天，根本没有进展。我有一个基本的Firestore查询，它检查当前用户id的用户名集合。然而，这似乎会使应用程序在功能运行后滞后，并且取决于屏幕上的数量，有时会使应用程序崩溃。注释掉该部分将使应用程序继续运行，不会出现任何问题。

  getUserData() {
    FirebaseFirestore.instance
        .collection('userNames')
        .where('uid', isEqualTo: FirebaseAuth.instance.currentUser!.uid)
        .get()
        .then((QuerySnapshot querySnapshot) {
      querySnapshot.docs.forEach((value) {
        setState(() {
          email = value["email"];
          deviceToken = value["deviceToken"];
          firstName = value["firstName"];
          lastName = value["lastName"];
          timestamp = value["timestamp"];
          date = value["date"];
          time = value["time"];
          institution = value["institution"];
          address = value["address"];
          points = value["points"];
          institutionName = value["institutionName"];
          placeID = value["placeID"];
          isAdmin = value["isAdmin"];
        });
      });
    });
  }

然而，这个看似无辜的代码块给了我这个错误：

我已经注意到，这个问题开始直接弹出后，建立谷歌广告。我遵循这个codelab，并跟踪我的步骤倒退和恢复到以前的版本，但我的应用程序继续这样做。https://codelabs.developers.google.com/codelabs/admob-ads-in-flutter#0

我还试着恢复到所有firebase和firestore包的旧版本，但我仍然会遇到这个错误。这是我所有的包裹。

我看到了，您正在尝试获取文档数据并将其中的值赋值给您的局部变量，对吗？

但是querySnapshot.docs实际上是一个List<QueryDocumentSnapshot<Object?>>类型的对象，它是每个文档的快照列表，因此为了访问您需要喜欢的文档的真实数据，如下所示：

  getUserData() {
  FirebaseFirestore.instance
      .collection('userNames')
      .where('uid', isEqualTo: FirebaseAuth.instance.currentUser!.uid)
      .get()
      .then((QuerySnapshot querySnapshot) {
    querySnapshot.docs.forEach((value) {
      setState(() {
        Map<String, dynamic> data = value.data() as Map<String, dynamic>;
        email = data["email"];
        deviceToken = data["deviceToken"];
        firstName = data["firstName"];
        lastName = data["lastName"];
        timestamp = data["timestamp"];
        date = data["date"];
        time = data["time"];
        institution = data["institution"];
        address = data["address"];
        points = data["points"];
        institutionName = data["institutionName"];
        placeID = data["placeID"];
        isAdmin = data["isAdmin"];
      });
    });
  });
}

这将将每个文档的实际数据分配给您的变量。

这应该没问题的。
