如何使用flutter在列表中记录查询firebase数据库？

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

class MyListPage extends StatefulWidget {
  @override
  _MyListPageState createState() => _MyListPageState();
}

class _MyListPageState extends State<MyListPage> {
  List<DocumentSnapshot> _dataList = [];

  @override
  void initState() {
    super.initState();
    _getDataFromFirebase();
  }

  Future<void> _getDataFromFirebase() async {
    QuerySnapshot querySnapshot = await FirebaseFirestore.instance
        .collection('your_collection') // 替换为你的集合名称
        .get();

    setState(() {
      _dataList = querySnapshot.docs;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('My List Page'),
      ),
      body: ListView.builder(
        itemCount: _dataList.length,
        itemBuilder: (context, index) {
          DocumentSnapshot document = _dataList[index];
          // 在这里根据需要从document中获取数据，并显示在列表项中
          return ListTile(
            title: Text(document['title']),
            subtitle: Text(document['description']),
          );
        },
      ),
    );
  }
}
