This is a quite simple script that cleans all your grade/flutter projects inside a folder

project_cleaner.md

Works on linux and macOS (and linux inside Windows)

1. Download the script (or copy paste it)
2. Put the script in the same folder than your projects
3. chmod +x your_script_name.sh, if you didn't change the name => `chmod +x projects_cleaner.sh
4. ./projects_cleaner.sh
5. Wait and enjoy!!

If you find this gist helpful, don't forget the star! :)
