所有的路由逻辑都在 BiliRouterDelegate build 中，那如果不光这几个页面，多达100个呢？

if (routeStatus == RouteStatus.home) {
      // 跳转首页时将其它页面进行出栈
      // 清空堆栈
      pages.clear();
      // 创建首页
      page = pagePack(HomePage(
        onJumpToDetail: (articleModel) {
          this.articleModel = articleModel;
          notifyListeners(); // 通知 Router 重建 RouterDelegate（通过 build() 方法）
        },
      ));
    } else if (routeStatus == RouteStatus.detail) {
      page = pagePack(DetailPage(articleModel: articleModel!));
    } else if (routeStatus == RouteStatus.login) {
      page = pagePack(LoginPage());
    } else if (routeStatus == RouteStatus.register) {
      page = pagePack(RegisterPage());
    } else if (routeStatus == RouteStatus.splash) {
      page = pagePack(SplashPage());
    }

RouteStatus getStatus(MaterialPage page) {
  if (page.child is SplashPage) {
    return RouteStatus.splash;
  } else if (page.child is HomePage) {
    return RouteStatus.home;
  } else if (page.child is LoginPage) {
    return RouteStatus.login;
  } else if (page.child is RegisterPage) {
    return RouteStatus.register;
  } else if (page.child is DetailPage) {
    return RouteStatus.detail;
  } else {
    return RouteStatus.unknown;
  }
}

类似这种代码就会越来越多。
这种问题怎么解决呢？
