Flutter 根据json生成实体类

实现步骤

1.安装插件

安装FlutterJsonBeanFactory插件

2.使用插件

右键想要生成实体类的文件夹点击JsonToDartBeanAction

输入类名和想要格式化的json串

这时会生成如下的实体类

import 'package:flutter_prevent_lost/generated/json/base/json_field.dart';
import 'package:flutter_prevent_lost/generated/json/login_bean_entity.g.dart';
import 'dart:convert';

@JsonSerializable()
class LoginBeanEntity {

    late String msg;
    late int code;
    late LoginBeanData data;
  
  LoginBeanEntity();

  factory LoginBeanEntity.fromJson(Map<String, dynamic> json) => $LoginBeanEntityFromJson(json);

  Map<String, dynamic> toJson() => $LoginBeanEntityToJson(this);

  @override
  String toString() {
    return jsonEncode(this);
  }
}

@JsonSerializable()
class LoginBeanData {

    late String token;
  
  LoginBeanData();

  factory LoginBeanData.fromJson(Map<String, dynamic> json) => $LoginBeanDataFromJson(json);

  Map<String, dynamic> toJson() => $LoginBeanDataToJson(this);

  @override
  String toString() {
    return jsonEncode(this);
  }
}

然后我们使用的时候调用里面的转换json的方法即可

var name =  _unameController.text;
var pass =  _upassController.text;
///创建Map 封装参数
Map<String,dynamic> map = Map();
map['username'] = name;
map['password'] = pass;
var result = await HttpGlobal.formDataHttpClient().post("app/login",data: map);
LoginBeanEntity login = LoginBeanEntity.fromJson(result.data);
