Flutter FutureBuilder不是使用来自sqlite的数据构建的

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

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return FutureBuilder<List<Map<String, dynamic>>>(
      future: _getDataFromSQLite(),
      builder: (context, snapshot) {
        if (snapshot.connectionState == ConnectionState.waiting) {
          return CircularProgressIndicator();
        } else if (snapshot.hasError) {
          return Text('Error: ${snapshot.error}');
        } else {
          // 数据可用时构建UI
          final data = snapshot.data;
          return ListView.builder(
            itemCount: data.length,
            itemBuilder: (context, index) {
              return ListTile(
                title: Text(data[index]['title']),
                subtitle: Text(data[index]['description']),
              );
            },
          );
        }
      },
    );
  }

  Future<List<Map<String, dynamic>>> _getDataFromSQLite() async {
    // 执行SQLite查询操作，返回数据
    final Database db = await openDatabase('path_to_database');
    final List<Map<String, dynamic>> data = await db.query('table_name');
    return data;
  }
}
