在futurebuilder中访问多个期货的结果

Future<List<String>> fetchFutures() async {
  // 模拟异步获取多个期货的结果
  await Future.delayed(Duration(seconds: 2));
  return ['期货1', '期货2', '期货3'];
}

Widget build(BuildContext context) {
  return FutureBuilder<List<String>>(
    future: fetchFutures(),
    builder: (BuildContext context, AsyncSnapshot<List<String>> snapshot) {
      if (snapshot.connectionState == ConnectionState.waiting) {
        // 如果异步操作正在进行中，显示加载中的UI
        return CircularProgressIndicator();
      } else if (snapshot.hasError) {
        // 如果异步操作发生错误，显示错误信息
        return Text('Error: ${snapshot.error}');
      } else {
        // 如果异步操作成功完成，显示期货的结果
        List<String> futures = snapshot.data;
        return ListView.builder(
          itemCount: futures.length,
          itemBuilder: (BuildContext context, int index) {
