如何在flutter中使用从MongoDB收到的json数据？

import 'package:http/http.dart' as http;
import 'dart:convert';

Future<List<dynamic>> fetchJsonDataFromMongoDB() async {
  final response = await http.get(Uri.parse('http://your-mongodb-api-url'));

  if (response.statusCode == 200) {
    // 请求成功，解析JSON数据
    return json.decode(response.body);
  } else {
    // 请求失败，抛出异常或处理错误
    throw Exception('Failed to fetch JSON data from MongoDB');
  }
}

import 'package:flutter/material.dart';

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return FutureBuilder<List<dynamic>>(
      future: fetchJsonDataFromMongoDB(),
      builder: (context, snapshot) {
        if (snapshot.hasData) {
          // 数据加载成功，构建ListView来展示数据
          return ListView.builder(
            itemCount: snapshot.data.length,
            itemBuilder: (context, index) {
              final item = snapshot.data[index];
              return ListTile(
                title: Text(item['title']),
                subtitle: Text(item['description']),
              );
            },
          );
        } else if (snapshot.hasError) {
          // 数据加载失败，显示错误信息
          return Text("${snapshot.error}");
        }

        // 数据加载中，显示加载指示器
        return CircularProgressIndicator();
      },
    );
  }
}
