firebase_storage object-not-found 所需引用处不存在对象

Question

任何人都可以帮我解决上述错误吗？

以下是代码。

class AuthController extends GetxController {
  static AuthController instance = Get.find();

  late Rx<File?> _pickedImage;

  File? get ProfilePhoto => _pickedImage.value;

  void pickImage() async {
    final pickedImage =
        await ImagePicker().pickImage(source: ImageSource.gallery);
    if (pickedImage != null) {
      Get.snackbar('Profile Picture',
          'You have successfully selected your profile picture');
    }
    _pickedImage = Rx<File?>(File(pickedImage!.path));
  }

  // upload to firebase storage
  Future<String> _uploadToStorage(File image) async {
    Reference ref = firebaseStorage
        .ref()
        .child('profilePics')
        .child(firebaseAuth.currentUser!.uid);

    UploadTask uploadTask = ref.putFile(image);
    TaskSnapshot snap = await uploadTask;
    String downloadUrl = await snap.ref.getDownloadURL();
    return downloadUrl;
  }

  // registering the user
  void registerUser(
      String username, String email, String password, File? image) async {
    try {
      if (username.isNotEmpty &&
          email.isNotEmpty &&
          password.isNotEmpty &&
          image != null) {
        // save out user to our ath and firebase store
        UserCredential cred = await firebaseAuth.createUserWithEmailAndPassword(
          email: email,
          password: password,
        );
        String downloadUrl = await _uploadToStorage(image);
        model.User user = model.User(
          name: username,
          email: email,
          uid: cred.user!.uid,
          profilePhoto: downloadUrl,
        );
        await firestore
            .collection('users')
            .doc(cred.user!.uid)
            .set(user.toJson());
      } else {
        Get.snackbar(
          'Error Creating Account',
          'Please enter all the details',
        );
      }
    } catch (e) {
      Get.snackbar(
        'Error Creating Account',
        e.toString(),
      );
    }
  }
}

我试图创建 authcontroller 来设置 firbease 存储上的用户详细信息。

这是我用过的常数。

如果需要更多信息，请告诉我。我被困住了，需要帮助，谢谢。

提前致谢。

不确定导致错误的原因，您应该首先更改 _uploadtostorage 函数以捕获一些错误，如

Future<String> _uploadToStorage(File image) async {


try {
    Reference ref = firebaseStorage
        .ref()
        .child('profilePics')
        .child(firebaseAuth.currentUser!.uid);
    UploadTask uploadTask = ref.putFile(image);
    TaskSnapshot snap = await uploadTask;
    String downloadUrl = await snap.ref.getDownloadURL();
    return downloadUrl;
} catch (e) {
    print('Error uploading image to Firebase Storage: $e');
    throw e; 
  }
}

尝试此操作并查看是否出现任何其他错误消息。
