Extending the Request class

Hi,

Im trying to extend the Symfony Request class to clean up some code. As a example:

<?php

    namespace Plugin\Name\Http\Requests;

    use Symfony\Component\HttpFoundation\Request;

    class ValidateExampleRequest extends Request
    {
        public function getEmail()
        {
            return $this->get('email');
        }
    }

After this I created a controller and injected my Request Class into the controller method.

<?php declare(strict_types=1);

    namespace Plugin\Name\Http\Controllers;
    
    use Shopware\Storefront\Controller\StorefrontController;
    use Symfony\Component\HttpFoundation\JsonResponse;
    use Symfony\Component\Routing\Attribute\Route;

    #[Route(defaults: ['_routeScope' => ['storefront']])]
    class ExampleController extends StorefrontController
    {
        #[Route(path: '/example', name: 'storefront.plugin.name.example', methods: ['get'])]
        public function example(ValidateExampleRequest $validateRequest)
        {
            return new JsonResponse([
                'email'    => $validateRequest->getEmail()
            ]);
        }
    }

After calling the URL I’m getting the following error:

Plugin\Name\Http\Controllers\ExampleController::example(): Argument #2 ($validateRequest) must be of type Plugin\Name\Http\Requests\ValidateExampleRequest, Symfony\Component\HttpFoundation\Request given, called in /var/www/html/vendor/symfony/http-kernel/HttpKernel.php on line 178

How can I inject my custom Request class to this controller method?

did you register your custom request class as a service? Show your services.xml as well
