flutter - 如何从路线类别列表中生成路线图

Question

我想通过创建路由列表来自动在我的应用程序中分配路由。
然后将映射此列表。我的目的是改进现有代码。
我知道这令人困惑，您可以通过以下代码更好地理解它:

MaterialApp(
        navigatorObservers: <NavigatorObserver>[observer],
        home: getWidgetByRouteName(hasRoute), //GameDetails(),
        routes: <String, WidgetBuilder>{
          SplashPage.routeName: (BuildContext context) => SplashPage(),
          Phone.routeName: (BuildContext context) => Phone(),
          OTP.routeName: (BuildContext context) => OTP(),
          Team.routeName: (BuildContext context) => Team(),

        },
      ),

我想将上面的代码转换成这种类型:

    List route = [SplashPage, Phone, OTP];

    Map<String, WidgetBuilder> namedRoutes = {};

    route.forEach((element) {
      namedRoutes[element.routeName] = (BuildContext context) => element();
    });



  MaterialApp(
        navigatorObservers: <NavigatorObserver>[observer],
        home: getWidgetByRouteName(hasRoute), //GameDetails(),
        routes: namedRoutes
      ),

并且如果您感到困惑，什么是routeName:

class SplashPage extends StatelessWidget {
  static const routeName = '/splash';
..
..
..
}

我收到此错误:

The following NoSuchMethodError was thrown building MainApp(dirty):
Class '_Type' has no instance getter 'routeName'.
Receiver: SplashPage
Tried calling: routeName

您不能从表示类的Type对象创建类的实例，至少不能没有镜像(Flutter和Web平台均不支持镜像)。
