Is there an existing issue for this?

Strangely, the content of flutter_service_worker.js disappears after running flutter run in release/profile mode. Everything generates correctly after flutter build web.

Steps to reproduce

  1. flutter build web (build/web/flutter_service_worker.js is generated correct and have content)
  2. flutter run -d chrome --release/profile (content from flutter_service_worker.js disappear)

Expected results

the content does not disappear

Actual results

flutter_service_worker.js is empty after flutter run release/profile mode
and service worker version can be updated only manually in the browser
