Issue
I have a existing plugin which supports Android and iOS. Now, i have tried to provide a web support. So, i followed the steps mentioned here,
https://flutter.dev/docs/get-started/web
It takes more time to run the app in chrome.
In console of chrome, i could see following message.

Solution
I have resolved this issue by replacing my reference packages from absolute path to hosted pub dev package reference in pubspec.yaml. Now, it takes few seconds to debug my flutter app.
