Steps to Reproduce

Hello. I want to add web support to my existing project. To do this I executed flutter create . which created web dir. Then I just executed flutter run -d chrome and error occured.

Expected results: Flutter Web work
Actual results: Flutter Web doesn't work with error in browser console:

Uncaught (in promise) TypeError: Failed to register a ServiceWorker for scope with script flutter_service_worker.js: A bad HTTP response code (404) was received when fetching the script.
