Angular pass parameters in templateurl in statepro

I am using a $stateprovider as follows from angular-ui-router in my angular application:

.state('order', {
        url: "/order/:id",
        templateUrl: "/myapp/order"
    })

In the above scenario, we are passing an id to the controller and we can call it as ui-sref="order({id: 1234})".

But now i want to make a direct call to the backend by not using a controller and pass the above as follows:

.state('order', {
        url: "/order",
        templateUrl: "/myapp/order/:id"
    })

But obviously my syntax is wrong here. How do i achieve this scenario?

I created working example. It is adjsuting thiw Q & A:

Trying to Dynamically set a templateUrl in controller based on constant

Let's have templates template-A.html and template-B.html in our example. The state def with templateProvider would look like this

  $stateProvider
    .state('order', {
      url: '/order/:id',

      templateProvider: function($http, $templateCache, $stateParams) {

        var id = $stateParams.id || 'A';
        var templateName = 'template-' + id + '.html';

        var tpl = $templateCache.get(templateName);

        if (tpl) {
          return tpl;
        }

        return $http
          .get(templateName)
          .then(function(response) {
            tpl = response.data
            $templateCache.put(templateName, tpl);
            return tpl;
          });
      },
      controller: function($state) {}
    });

And now we can call it like this

  <a href="#/order/A">
  <a href="#/order/B">

Check it here

And what's more, with latest version of angularjs we can even make it super simple:

$templateRequest

Updated plunker

.state('order', {
  url: '/order/:id',

  templateProvider: function($templateRequest, $stateParams) {

    var id = $stateParams.id || 'A';
    var templateName = 'template-' + id + '.html';
    return $templateRequest(templateName);
  },
  controller: function($state) {}
});
