1.首先打开json_to_dart https://javiercbk.github.io/json_to_dart/ 页面如下: 2.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 3.创建一个Dart类,将类名自行修改一下 4,使用方式如下 方式二:安装FlutterJsonBeanFactory插件生成 首先安装FlutterJsonB...
classUser{finalString name;finalString email;User(this.name,this.email);User.fromJson(Map<String,dynamic>json):name=json['name'],email=json['email'];Map<String,dynamic>toJson()=><String,dynamic>{'name':name,'email':email,};} 2.json字符串变成model (两步) Map userMap=json.decode(json...
Hi, Welcome! This is a plugin to generate Dartmodel classfrom JSON string, in another word, a plugin that converts JSON string to Dartmodel class(Json to Dart) Overview This is a very cool tool for Flutter developers, it can convert a JSON string to Dartmodel class. The tool could not...

Given a JSON string, this library will generate all the necessary Dart classes to parse and generate JSON. This library is designed to generate Flutter friendly model classes following theflutter's doc recommendation. Caveats When an empty array is given, it will create a List. Such weird behav...

方式一: dart:convert (不推荐) Flutter 有一个内置的 dart:convert 的库,这个库包含了一个简单的 JSON 编码器和解码器。 使用fromJson和toJson实现序列化和反序列化 全手写代码,在多人协作的团队中不建议使用 官方文档 示例代码: classUser{ finalStringname; ...
