If you can't use RequestStack directly, you could create a factory service that returns the current request using RequestStack.

# services.yml
app.request:
    class: Symfony\Component\HttpFoundation\RequestStack
    factory: [ @request_stack, getCurrentRequest ]

Then you can access the current request using the app.request service.
