如何使用streambuilder flutter访问firestore中的数据

dependencies:
  cloud_firestore: ^2.5.3

import 'package:firebase_core/firebase_core.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}

import 'package:flutter/material.dart';
import 'package:cloud_firestore/cloud_firestore.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Firestore Data'),
        ),
        body: StreamBuilder<QuerySnapshot>(
          stream: FirebaseFirestore.instance.collection('your_collection').snapshots(),
          builder: (BuildContext context, AsyncSnapshot<QuerySnapshot> snapshot) {
            if (snapshot.hasError) {
              return Text('Error: ${snapshot.error}');
            }

            if (snapshot.connectionState == ConnectionState.waiting) {
              return CircularProgressIndicator();
            }

            return ListView(
              children: snapshot.data!.docs.map((DocumentSnapshot document) {
                Map<String, dynamic> data = document.data() as Map<String, dynamic>;
                return ListTile(
                  title: Text(data['title']),
                  subtitle: Text(data['subtitle']),
                );
              }).toList(),
            );
          },
        ),
      ),
    );
  }
}
