  1. Go to flutter\bin\cache and remove a file named: flutter_tools.stamp
rm ~/snap/flutter/common/flutter/bin/cache/flutter_tools.stamp
  1. Go to flutter\packages\flutter_tools\lib\src\web and open the file chrome.dart. (for linux is at
vi ~/snap/flutter/common/flutter/packages/flutter_tools/lib/src/web/chrome.dart
  1. Find '--disable-extensions'
  2. Add '--disable-web-security',
flutter run -d chrome --web-port=4200 --web-renderer=html

This project is a starting point for a Flutter application.
