dart - How to unspecify a port number while not running flutter web

Question

Is there any way to stop Flutter web with a Headless-Server target, I managed to specify to localhost:8080 ?

Whenever I try to run any other non flutter aplication using port 8080 in localhost I end up with

http://localhost:8080/flutter_service_worker.js

How I created the Headless-Server target

flutter run -d headless-server --web-port=8080
