Can you please provide your flutter doctor -v, your flutter run --verbose and a minimal complete reproducible code sample?

Thank you

@aihamhasan
It seems to be an issue with your VSCode setup / config rather than framework. See below similar issues and underlying comments / solutions and check if they help to resolve your issue.

Removing spaces on the Projects Folder Path Solves the Issue.
ex: Change demo app to demo_app
