我将用户照片存储在以其uid命名的firebase存储文件夹/路径中。删除文件不会有问题，但是当我试图删除文件夹/路径时包含它，我得到了这个异常和其他异常，尽管文件夹被删除:
这是一个delete方法的代码片段:E/StorageException(16352): StorageException has occurred.日志含义对象在该位置不存在。
// Delete Profile Photo
try {
final profilePhotoRef = FirebaseStorage.instance.ref().child('images/${user.uid}');
// delete every file within the path
profilePhotoRef.listAll().then((value) {
for (var element in value.items) {
FirebaseStorage.instance.ref(element.fullPath).delete();
}
});
// Now delete the containing folder/path
profilePhotoRef.delete(); // --> here is the problem
} on FirebaseException catch (e) {
print("Failed with error '${e.code}': ${e.message}");
}
，这是我得到的异常列表:

提前谢谢你，花了我很多时间，我没有找到一个解决方案。
实际上Google Cloud Storage并没有真正的"文件夹"，这就是为什么你会得到" Object does not exist at location ";例外。
在Cloud Storage控制台中，bucket中的文件以文件夹的层次树形式呈现(就像本地硬盘上的文件系统一样)，但这只是呈现文件的一种方式:bucket中没有真正的文件夹/目录。Cloud Storage控制台只是使用文件路径的不同部分来"模拟"。一个文件夹结构，使用"/"分隔符字符。
这个关于云存储和gsutil的文档很好地解释和说明了这种"分层文件树的错觉"。
