a router config mapping solution based on source_gen through annotation

1. Notice: your page should own a constuctor that can be initialized with unique param, then Annotate the page class with @ARoute
   example:

   @ARoute(url: 'myapp://pagea')
   class A {
    A(MyRouteOption option): super();
   }

2. Annotate your own router class with @ARouteRoot
   example:

   @ARouteRoot()
   class MyRouter {}

3. run the build_annotation_route.sh in your workspace Or just run the command below in your workspace
   build:

    flutter packages pub run build_runner build --delete-conflicting-outputs

   suggest you running the clean command before build:
   clean:

    flutter packages pub run build_runner clean

4. now you can get the instance
   example:

   @ARouteRoot()
   class Router {
    ARouterInternal internal = ARouterInternalImpl();
    dynamic getPage(MyRouteOption option) {
      return internal.findPage(
          ARouteOption(option.urlpattern, option.params), option);
    }
   }
   
   class MyRouteOption {
    String urlpattern;
    Map<String, dynamic> params;
   }

5. examples placed in 'lib/example/*'

add packages to dev_dependencies in your pubspec.yaml
example:

dev_dependencies:
  annotation_route: any

clone the code, then put it into your workspace, announce it in your pubspec.yaml exxample:

dev_dependencies:
  annotation_route:
    path: annotation_route

一个以注解方式实现的路由映射解决方案，基于 source_gen

1. 注意: 你的页面应该实现指定的构造器，一个接受唯一参数的构造器，然后使用@ARoute 注解你的页面类
   例：

   @ARoute(url: 'myapp://pagea')
   class A {
    A(MyRouteOption option): super();
   }

2. 使用 @ARouteRoot 注解 你自己的 router 类 例：

   @ARouteRoot()
   class MyRouter {}

3. 在你的工作目录下运行 build_annotation_route.sh 脚本，或者运行如下命令:
   build:

    flutter packages pub run build_runner build --delete-conflicting-outputs

   建议在执行 build 命令前，先执行如下命令:
   clean:

    flutter packages pub run build_runner clean

4. 现在你可以使用它来获取类的实例了
   例：

   @ARouteRoot()
   class Router {
    ARouterInternal internal = ARouterInternalImpl();
    dynamic getPage(MyRouteOption option) {
      return internal.findPage(
          ARouteOption(option.urlpattern, option.params), option);
    }
   }
   
   class MyRouteOption {
    String urlpattern;
    Map<String, dynamic> params;
   }

5. 具体代码可以参考 lib/example/*下的文件

在你的 pubspec.yaml 文件下声明
例：

dev_dependencies:
  annotation_route: any

拷贝代码至你的工作目录，在你的 pubspec.yaml 文件下声明
例：

dev_dependencies:
  annotation_route:
    path: annotation_route
