flutter如何将来自多个json api urls的数据放入一次？

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

Future<List<dynamic>> fetchData(String url) async {
  final response = await http.get(Uri.parse(url));
  if (response.statusCode == 200) {
    return json.decode(response.body);
  } else {
    throw Exception('Failed to fetch data');
  }
}

Future<List<dynamic>> fetchMultipleData(List<String> urls) async {
  final List<Future<dynamic>> futures = [];
  for (String url in urls) {
    futures.add(fetchData(url));
  }
  return await Future.wait(futures);
}

void main() async {
  List<String> apiUrls = [
    'https://api.example.com/data1',
    'https://api.example.com/data2',
    'https://api.example.com/data3'
  ];

  try {
    List<dynamic> data = await fetchMultipleData(apiUrls);
    // 处理获取到的数据
    print(data);
  } catch (e) {
    // 处理错误
    print(e);
  }
}
