無法從 Dart Flutter FireBase 中提取數據

Question

WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();

FirebaseFirestore FS = FirebaseFirestore.instance;

CollectionReference TC = FirebaseFirestore.instance.collection("oneSignal");
var docs = TC.doc("xcG9kfCWnUK7QKbK37qd");
var response = await docs.get();

var veriable = response.data();

print(veriable);

我正在嘗試使用此代碼從 FireBase FireStore 中提取數據。 但是我收到這樣的錯誤：

規則代碼：

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /oneSignal/{signalId} {
        allow write;
    }
  }
}

我該如何解決？ 先謝謝您的幫助。

添加allow read規則：

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /oneSignal/{signalId} {
        allow read, write: if true;
    }
  }
}
