Dart redstone web application

Let's say I configure redstone as follows

    @app.Route("/raw/user/:id", methods: const [app.GET])
    getRawUser(int id) => json_about_user_id;

When I run the server and go to /raw/user/10 I get raw json data in a form of a string.

Now I would like to be able to go to, say, /user/10 and get a nice representation of this json I get from /raw/user/10.

Solutions that come to my mind are as follows:

1. First
   
   
   
   • create web/user/user.html and web/user/user.dart, configure the latter to run when index.html is accessed
   
   
   • in user.dart monitor query parameters (user.dart?id=10), make appropriate requests and present everything in user.html, i.e.
   
   
   
   

         var uri = Uri.parse( window.location.href );
         String id = uri.queryParameters['id'];
         new HttpRequest().getString(new Uri.http(SERVER,'/raw/user/${id}').toString() ).then( presentation )

A downside of this solution is that I do not achieve /user/10-like urls at all.

2. 
   

   Another way is to additionally configure redstone as follows:

   
   

   
   @app.Route("/user/:id", methods: const [app.GET])
   getUser(int id) => app.redirect('/person/index.html?id=${id}');
   
   

in this case at least urls like "/user/10" are allowed, but this simply does not work.

How would I do that correctly? Example of a web app on redstone's git is, to my mind, cryptic and involved.

I am not sure whether this have to be explained with connection to redstone or dart only, but I cannot find anything related.
