使用@jsonserializable（）时，如何在飞镖/颤动中具有动态多元值？

Question

我正在使用json_annotation库的扑朔迷离，并且有一个用于表示来自一个API的JSON响应的数据类。

import 'package:json_annotation/json_annotation.dart';
import 'package:app/dtos/user.dart';
import 'package:app/dtos/limited_user.dart';


part 'pending_project.g.dart';

@JsonSerializable()
class PendingProject {
  @JsonKey(name: "user")
  final User|LimitedUser user; // here I might have sometimes returned User type other types LimitedUser

  @JsonKey(name: "updatedAt")
  final String updatedAt;

  PendingProject(this.user, this.updatedAt);

  factory PendingProject.fromJson(Map<String, dynamic> json) =>
      _$PendingProjectFromJson(json);

  Map<String, dynamic> toJson() => _$PendingProjectToJson(this);
}

API基于某些逻辑返回用户字段的不同值。 Sometimes objects of type User other types of type LimitedUser

I have both those objects defined but cannot make it work in the json schema above.

How can I leave user object as dynamic maybe or json string and further parse manually in code or some other solution

Both User and LimitedUser have one common field named type< /代码>，这使我们能够区分回来的东西。

for User, type="user"

for LimitedUser, type="limitedUser"

all the other fields can be different we cannot assume anything else

PS: pending_project.g.dart是通过运行flutter packages pub run build build_runner构建的自动生成的文件
