我只是想找到一种方法来将json响应（从REST API）转换为POJO（在android中使用），这样我就可以将接收到的数据使用到我的应用程序中了，因为使用Map不会足够m接收有点复杂，包含3个级别的数组（数组内部的数组在数组内部的数组）。
我正在使用Dio库进行api调用，我可以成功进行API调用，并在控制台上毫无问题地打印数据。谁能协助我达成目标？
以下是我得到的答复。

因此，在尝试使用json_serializable库后，我想出了自己的解决方案，它根本不需要任何外部库，并且像一个魅力一样工作。这样，我必须编写更少的样板代码，我认为这是一种干净的方法。
这是制作模型的方法
class SideMenuRes { final int status; final String message; final List<SideMenuDatum> sideMenuData; SideMenuRes({this.status, this.message, this.sideMenuData}); factory SideMenuRes.fromJson(Map json) { return SideMenuRes( status: json['status'], message: json['message'], sideMenuData: json['status'] == 200 ? (json['data'] as List).map((i) => new SideMenuDatum.fromJson(i)).toList() : null, ); } } class SideMenuDatum { final Menu menu; SideMenuDatum({this.menu}); factory SideMenuDatum.fromJson(Map json) { return SideMenuDatum( menu: Menu.fromJson(json['menu']), ); } } class Menu { final String megamenu_id; final String language_id; final String title; final String description; final List<SubMenu> subMenu; Menu({this.megamenu_id, this.language_id, this.title, this.description, this.subMenu}); factory Menu.fromJson(Map json) { return Menu( megamenu_id: json['megamenu_id'], language_id: json['language_id'], title: json['title'], description: json['description'], subMenu: json['submenu'] != null ? (json['submenu'] as List).map((i) => new SubMenu.fromJson(i)).toList() : null ); } } class SubMenu { final Zero zero; final List<SubSubMenu> subSubMenu; SubMenu({this.zero, this.subSubMenu}); factory SubMenu.fromJson(Map json) { return SubMenu( zero: Zero.fromJson(json['0']), subSubMenu: (json['subsubmenu'] as List).map((i) => new SubSubMenu.fromJson(i)).toList() ); } } class Zero { final Info info; Zero({this.info}); factory Zero.fromJson(Map json) { return Zero( info: Info.fromJson(json['info']), ); } } class SubSubMenu { final InfoSub infoSub; SubSubMenu({this.infoSub}); factory SubSubMenu.fromJson(Map json) { return SubSubMenu( infoSub: InfoSub.fromJson(json['infosub']) ); } } class InfoSub { final String megamenu_id; final String language_id; final String title; final String description; InfoSub({this.megamenu_id, this.language_id, this.title, this.description}); factory InfoSub.fromJson(Map json) { return InfoSub( megamenu_id: json['megamenu_id'], language_id: json['language_id'], title: json['title'], description: json['description'] ); } } class Info { final String megamenu_id; final String language_id; final String title; final String description; Info({this.megamenu_id, this.language_id, this.title, this.description}); factory Info.fromJson(Map json) { return Info( megamenu_id: json['megamenu_id'], language_id: json['language_id'], title: json['title'], description: json['description'] ); } }
并这样称呼它
SubMenuRes subMenuRes = SubMenuRes.fromJson(response.data);
而已！
