route name

[mitisa]

Hi dear
I create app and route helper method same laravel helper methods and my code this is:
function app($abstract = null, array $parameters = [])
{
if (is_null($abstract)) {
return Container::getInstance();
}

`return Container::getInstance()->make($abstract, $parameters);`

}
function route($name, $parameters = [], $absolute = true)
{
return app('url')->route($name, $parameters, $absolute);
}
but when call route and send route name for example route('profile') i have this error:

Fatal error: Uncaught ReflectionException: Class url does not exist in vendor\illuminate\container\Container.php:877
I think laravel use RoutingServiceProvider and I need provider
please help
thanks
