我为管理员登录编写的代码：

import \'package:cloud_firestore/cloud_firestore.dart\';\nimport \'package:flutter/material.dart\';\n\nclass FirebaseServices {\n  static Future<DocumentSnapshot> adminSignIn(id) async {\n    var res =\n        await FirebaseFirestore.instance.collection("admin").doc(id).get();\n    return res;\n  }\n}\n

我收到的错误如下：

import \'package:cloud_firestore/cloud_firestore.dart\';\nimport \'package:flutter/material.dart\';\n\nclass FirebaseServices {\n  static Future<DocumentSnapshot> adminSignIn(id) async {\n    var res =\n        await FirebaseFirestore.instance.collection("admin").doc(id).get();\n    return res;\n  }\n}\n

您还可以访问该项目的存储库。

我试着跑flutter doctor -v。进而：
