Flutter Routing在脚手架中渲染？

Question

return MultiProvider(
  providers: getProviders(context),
  child: MaterialApp(
    onGenerateRoute: AppRouter.router.generator,
    title: 'Gathered Reporting',
    home: Consumer<AppProvider>(
        builder: (context, app,_){
          if(app.isLoggedIn){
            return Scaffold(
              body: <--show router page
            );
          }else{
            return showLogin()
          }
        }
    ),
  )
);

我如何让路由器在体内显示内容？
