Question

我正在尝试将我的图像存储在 firebase 中并检索它。但是我被卡住了，因为 StorgeTaskSnapshot 不起作用，它说“未定义的类/方法”。我如何解决它？是否是由于更新的软件包版本导致的另一个问题？

这是一张图片 -

编辑：我忘记添加代码，所以我正在做 -

这是完整的文件 -

/R

请检查行 - 106-120、129-142 和 144-173、175-198，因为在这些行中，您可能会找到出现问题的代码，而您不必搜索它

这是我的日志 -

my_colors <- c(
  `liberal`        = "darkred",
  `conservative`   = "darkblue",
  `ndp`            = "orange",
  `bq`             = "cyan",
  `green`          = "darkgreen",
  `laurier1`       = "darkorchid",
  `laurier2`       = "gold")

#' My colors

#' @format a vector with the colors I need

如果您更新了依赖项，则可能是您使用了旧语法。

您能否尝试使用更新的上传语法。下面是一个例子：

import 'dart:io';
import 'package:firebase_storage/firebase_storage.dart' as firebase_storage;

firebase_storage.FirebaseStorage storage =
    firebase_storage.FirebaseStorage.instance;

class StorageService {
  static Future<String> uploadFile(String path, File file) async {
    try {
      firebase_storage.Reference storageReference =
          firebase_storage.FirebaseStorage.instance.ref(path);
      await storageReference.putFile(file);

      String downloadURL = await storageReference.getDownloadURL();
      return downloadURL;
    } catch (e) {
      return null;
    }
  }
}

你像这样使用它：

String photoURL = await StorageService.uploadFile(
        'users/${_auth.currentUser.uid}/${Path.basename(_image.path)}', _image);

您的函数如下所示：

uploadImageToFirestoreAndStorage() async {
    String mFileName = id;
    Reference storageReference = FirebaseStorage.instance.ref('path_in_storage').child(mFileName);
    await storageReference.putFile(imageFileAvatar);

    String photoUrl = await storageReference.getDownloadURL();

    try{
    await FirebaseFirestore.instance.collection("users").doc(id).update({
      "photoUrl": photoUrl,
      "aboutMe": aboutMe,
      "nickname": nickname,
    });
    }catch(e){
    print('e $e');
    }

    print('photoUrl $photoUrl');
    await preferences.setString("photoUrl", photoUrl);

    setState(() {
      isLoading = false;
    });

    Fluttertoast.showToast(msg: "Updated successfully");
  }

StorageTaskSnapshot 在颤动中不起作用
