方式一

1..将json数据赋值到输入框中，点击创建Dart类，然后右边就是生成好的Dart代码，类名可以复制到编辑器后自行修改

2.创建一个Dart类，将类名自行修改一下

3.使用

 /*先将字符串转成json*/
    Map json = jsonDecode(jsonData);
    /*将Json转成实体类*/
    NewsBean newsBean=NewsBean.fromJson(news);
    /*取值*/
    String sats = newsBean.result.stat;

方式二

安装FlutterJsonBeanFactory插件生成

首先安装FlutterJsonBeanFactory这个插件，安装方式很简单，这里我就不说了。

安装完成后右键包目录，选择new

然后选择dart bean class File from JSON

然后将json数据粘贴至输入框，输入类名，点击make即可
