Firebase StorageTaskSnapshot在颤振模式下不工作

我正在尝试将我的图像存储在firebase中并检索它。但我被卡住了，因为StorgeTaskSnapshot不工作，它说“未定义的类/方法”。我怎么修理它？这是由于更新的软件包版本引起的另一个问题吗

这是一张照片-

编辑：我忘了添加代码，所以我正在添加-

如果更新了依赖项，则可能是使用了旧语法

你能用更新的语法上传吗。以下是一个例子：

导入'dart:io'；
导入“package:firebase_storage/firebase_storage.dart”作为firebase_storage；
firebase_存储。firebase存储=
firebase_storage.FirebaseStorage.instance；
类存储服务{
静态未来上传文件（字符串路径，文件文件）异步{
试一试{
firebase_storage.Reference storageReference=
firebase_storage.FirebaseStorage.instance.ref（路径）；
等待storageReference.putFile（文件）；
String downloadURL=wait-storageReference.getDownloadURL（）；
返回下载URL；
}捕获（e）{
返回null；
}
}
}

您可以这样使用它：

String photoURL=wait-StorageService.uploadFile(
'users/${u auth.currentUser.uid}/${Path.basename（\u image.Path）}'，\u image）；

您的函数如下所示：

uploadImageToFirestoreAndStorage（）异步{
字符串mFileName=id；
Reference-storageReference=FirebaseStorage.instance.ref（'path_in_storage'）.child（mFileName）；
等待storageReference.putFile（imageFileAvatar）；
字符串photoUrl=wait-storageReference.getDownloadURL（）；
试一试{
等待FirebaseFirestore.instance.collection（“用户”）.doc（id）.update({
“photoUrl”：photoUrl，
“aboutMe”：aboutMe，
“昵称”：昵称，
});
}捕获（e）{
打印（'e$e'）；
}
打印（'photoUrl$photoUrl'）；
wait preferences.setString（“photoUrl”，photoUrl）；
设置状态（）{
isLoading=false；
});
flattertoast.showtoos（消息：“更新成功”）；
}

始终共享代码片段，而不是images@griffins是的，事实上我错忘了。否则我总是上传。我试图使用更新的代码，但没有成功。非常非常感谢你的帮助，但是你能告诉我我在上面代码中的错误吗，因为我的图片没有更新，而我的昵称和个人简历没有更新。这将非常有帮助。我已经更新了答案。底部是一个应该可以工作的函数版本。如果你不想上传rooth文件夹中的图片，那么只需添加一个应该上传的路径。它仍然无法正常工作。再说一次，它没有得到更新。你有任何错误吗？您是否具有写入该路径的正确权限？我已再次编辑我的帖子，您可以查看调试详细信息
