Flutter Dart 创建Base类添加泛型

Posted 2021-08-30 安果移不动

首先看下我们的泛型类

class BaseBean<T> {
  late String msg;
  late int code;
  T? data;
}

解析Dio返回的String数据

 Map<String, dynamic> jsonData = jsonDecode(response.data);      
   var bean = BaseBean<T>();
      bean.msg = jsonData['msg'];
      bean.code = jsonData['code'];
      if (jsonData.containsKey("data")) {
        bean.data = JsonConvert.fromJsonAsT(jsonData['data']);
      }
