这是我的JSON：

{
'malls' : [{'id':1 , 'name': 'salam'},{'id':2 , 'name': 'salam2'}]
}

这是我的建模JSON类：

class MALL {
  final int id;
  final String name;

  MALL({required this.id, required this.name});

  factory MALL.fromJson(Map<String, dynamic> data) {
    return MALL(id: data['id'], name: data['name']);
  }
}

class City {
  final List<MALL> malls;

  City({required this.malls});
  factory City.fromJson(Map<String, dynamic> data) {
    var list = data['malls'] as List;
    List<MALL> mallList = list.map((i) => MALL.fromJson(i)).toList();
    return City(malls: mallList);
  }
}

这是我的get方法：

Future<List<MALL>> get() async {
  var response = await http.get(Uri.parse(URL), headers: {"authorization": "Bearer ${token}", "Content-Type": "application/json"});
  var data = jsonDecode(response.body);
  City api = City.fromJson(data);
  return data['malls'];
}

我得到这个输出：

[Instance of 'MALL', Instance of 'MALL']

我想在输出中得到我的类示例的JSON。我如何将示例转换为我的数据？这意味着我想在输出中返回我的JSON，并且我可以在我的FutureBuilder中访问mall的键。
