While using a @Route annotation in the controller, the dev cache is properly invalidated, if the route requirements are written directly in the annotation. But when using container parameters in requirements, the cache is not invalidated automatically and you need to delete cache/dev directory manually.

See the example: If another option is added to config, the route is not matched until the cache directory is manually deleted:

# config.yml
parameters:
    routing.type_slug: article|category

// DefaultController.php
/**
 * @Route("/{typeSlug}/", name="homepage", requirements={"typeSlug": "%routing.type_slug%"})
 */
public function indexAction(string $typeSlug, Request $request)
