历史上最简单的生成树

生成树方法

方法一

一、 定义menu.json文件

[
  {
    "index": 1,
    "name": "首页",
    "icon": "home"
  },
  {
    "index": 2,
    "name": "系统配置",
    "children": [
      { "index": 21, "name": "基础设置", "page": "a1" }
    ]
  },
 ]

二、手动改写 route_mapper.dart

static final Map<String, Widget Function()> routes = {
   "a1": () => const AdminDashboardPage(),
 };

方法二

自动生成路由表

 运行  dart gen_route.dart   自动生成 route_mapper.dart文件

      条件：
        json中 page字段 和view下文件 类名一致

      例如：p_1.dart

        class P1 extends StatelessWidget {
             const P1({super.key});
             @override
             Widget build(BuildContext context) {
               return Text("P1");
             }
           }
   
      json 文件 
         {
           "index": 1,
           "name": "首页",
           "page": "P1",  ----> 这里要一致
           "icon": "home"
         },
