Class issue

[Keust]

I experience a challenge when running.

If i use literal your example this happens:
Class 'Slim\Http\Request' not found in C:\Users\...\Documents\NewProject\vendor\zguillez\slim-mobile-detect\src\Http\MobileRequest.php on line 7

Also when I try to add the method in a controller (e.g. HomeController). Before the functions I declare the function:

use Slim\Http\MobileRequest as MobileRequest;
class HomeController
{
    public function mobile($request, $response, $args)
    {
        $request = new MobileRequest($request);
    }
}

// Same error: Class 'Slim\Http\Request' not found in C:\Users...\Documents\NewProject\vendor\zguillez\slim-mobile-detect\src\Http\MobileRequest.php on line 7

Could you help me?
