php - Symfony wildcard host route with no named parameter

I want to host 2 different domains inside a single Symfony 4 application, so I'm using@Route'shost parameter to declare the domain each page belongs to:

/**
 * @Route("/foo", name="foo", host="example.com")
 */
Copy code

This works fine; however, for my local dev server, I will typically use a domain likeexample.dev instead. So the route needs to match multiple extensions. I tried using a named placeholder for this purpose:

/**
 * @Route("/foo", name="foo", host="example.{ext}")
 */
Copy code

This works fine for routing, but not for URL generation. For example, if a Twig template attempts to use{{ path('foo') }}, I now get the following error:

Some mandatory parameters are missing ("ext") to generate a URL for route "foo".

Is there a way to add a wildcard for the host, while still allowing route generation without passing a parameter?

I know the question sounds odd, as routing must be bi-directional, but how is this typically handled when one needs to have a dev environment with different domains?

Is there maybe a way to provide a global, default value for theext parameter?
