flutter Json转Dart Model类

Json转Dart Model类

• 方式1：通过在线网站进行转换
  • 地址1：https://app.quicktype.io/ 多种语言都可以转
  • 地址2：https://www.geekailab.com/io/tools/json-to-dart/ 只能转dart
• 方式2：在编译器中下载相关转换插件
  • VScode:json To Dart (手动新建文件夹将json数据复制到文件中 右键点击（Convert JSON from Clipboard Here） 会在当前文件中自动生成)
  • androidStudio:jsonToDart （右键点击新建文件 （Json To Dart）将json数据复制进去进行生成 ）

android Studio 上使用flutter Json转Dart Model类

• 打开创建面板
  
• 转换方式可配置
  
• 创建
  • class Name 既是文件名也是 类名
    
• 示例json

{"code":200,"data":{"name":"笑哈哈","phone": "4344","hoppy":["唱","跳","rap"]},"msg":"操作成功","success":true,"time":"2024年8月29日14:33:47"
}

• 转换结果

/// code : 200
/// data : {"name":"笑哈哈","phone":"4344","hoppy":["唱","跳","rap"]}
/// msg : "操作成功"
/// success : true
/// time : "2024年8月29日14:33:47"class UserInfo {UserInfo({this.code, this.data, this.msg, this.success, this.time,});UserInfo.fromJson(dynamic json) {code = json['code'];data = json['data'] != null ?
