E / StorageUtil (5389): ошибка при получении токена java .util.concurrent.ExecutionException: com.google.firebase.internal.api.FirebaseNoSignedInUserException

Question

Я пытаюсь загрузить файл в Firebase, и, по моему мнению, он не работает в следующих функциях. Если у кого-то из вас возникла подобная проблема при использовании Firebase для загрузки файлов, я был бы признателен, если бы вы могли поделиться своим решением. Спасибо

 void uploadFile() async {
    String fileName = basename(sampleFile.path);
    final StorageReference storageFileRef = FirebaseStorage.instance.ref().child(fileName);
    var timeKey = new DateTime.now();
    final StorageUploadTask uploadTask = storageFileRef.child(timeKey.toString() + ".pdf").putFile(sampleFile);
    StorageTaskSnapshot taskSnapshot = await uploadTask.onComplete;
    var FileUrl = await (await uploadTask.onComplete).ref.getDownloadURL();
    url = FileUrl.toString();
    print("File url = $url");
    saveToDataBase(url);
  }

  void saveToDataBase(String url) {
    var dbTimeKey = new DateTime.now();
    var formatDate = new DateFormat('MMM d, yyyy');
    var formatTime = new DateFormat('EEEE, hh:mm: aaa');

    String date = formatDate.format(dbTimeKey);
    String time = formatTime.format(dbTimeKey);

    DatabaseReference ref = FirebaseDatabase.instance.reference();
    var data = {
      "file" : url,
      "description" : _myValue,
      "date" : date,
      "time" : time,
    };

    ref.child("Reports").push().set(data);

  }

Я получаю следующую ошибку. Я предоставил их и дальше. Ваша помощь очень ценится.

Правила, установленные в Firebase, показаны ниже, и анонимная аутентификация включена.

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write: if true;
    }
  }
}

Полный вывод показан ниже.
