What is the method to retrieve information specifically for the present user using Flutter and Firestore?

edit

To retrieve information specifically for the present user using Flutter and Firestore, you can follow these steps:

1. First, you need to get the current user's unique identifier. You can use Firebase Auth to get this identifier.

import 'package:firebase_auth/firebase_auth.dart';
FirebaseUser user = await FirebaseAuth.instance.currentUser();
String uid = user.uid;

1. Then, you can use Firestore to query for documents that match the user's unique identifier.

import 'package:cloud_firestore/cloud_firestore.dart';
QuerySnapshot snapshot = await Firestore.instance.collection('users').where('uid', isEqualTo: uid).getDocuments();

1. Finally, you can extract the data from the document using the data property.

Map<String, dynamic> userData = snapshot.documents[0].data;

Note: You need to make sure that you have set up the Firestore rules to only allow the current user to access their own data.
