如何使用Firestore在flutter中正确访问要用于列表的集合数据

dependencies:
  cloud_firestore: ^2.5.3

import 'package:cloud_firestore/cloud_firestore.dart';

FirebaseFirestore firestore = FirebaseFirestore.instance;

Stream<QuerySnapshot> collectionStream = firestore.collection('your_collection').snapshots();

StreamBuilder<QuerySnapshot>(
  stream: collectionStream,
  builder: (BuildContext context, AsyncSnapshot<QuerySnapshot> snapshot) {
    if (snapshot.hasError) {
      return Text('Error: ${snapshot.error}');
    }

    if (snapshot.connectionState == ConnectionState.waiting) {
      return Text('Loading...');
    }

    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(),
    );
  },
);
