Question

我获取用户ID时出错。

代码为：

import'package：cloud_firestore / cloud_firestore.dart';     导入'package：flutter / cupertino.dart';

class UserManagement {

  Firestore db = Firestore.instance;
  var ui = db.currentUser();

  storeNewUser(user, context) {
    db.collection('/users').add({
    'email': 'thee',
    'uid': ui;
    }).then((value) {
      Navigator.pushNamed(context, 'Home');
    }).catchError((e) {
      print(e);
    });
  }
}

Firestore单例实例没有属性或方法调用currentUser。您可能会想到Firebase身份验证。
