如何在Flutter Firestore中获取用户ID

问题描述

我是扑朔迷离的新手，而且我不知道如何在Firestore中编写特定的文档(userId).

I'm new in flutter and I don't know how to write in a particular document(userId) in firestore.

我希望我的数据库是这样的:用户(集合) |-> userId |->名称:Richie

I want my database is like:users(collection) |-> userId |->name : Richie

这是我的尝试:

Future<FirebaseUser> user =FirebaseAuth.instance.currentUser();
DocumentReference ref =Firestore.instance.collection('users').document(user.uid);

请帮助

推荐答案

在访问id之前，您需要等待获取FirebaseUser.我在下面为您演示了一个简单的函数.

You need to await to get the FirebaseUser before you can access the id.I created a simple function below demonstrating this for you.

Future<DocumentReference> getUserDoc() async {
  final FirebaseAuth _auth = FirebaseAuth.instance;
  final Firestore _firestore = Firestore.instance;

  FirebaseUser user = await _auth.currentUser();
  DocumentReference ref = _firestore.collection('users').document(user.uid);
  return ref;
}
