The script cleans the ios folder by deleting all files and folders that are being used to cache data. Then runs the Flutter app.

The script assumes that there are two entries (main file) for the project one is being used if the build is a dev build and the other will be used if it is a production build. You need to pass -r to the command if it is a production build.

I usually put this file under the scripts folder at the root of the project. Use the following commands when you want to run it:

dev build:

sh scripts/clean_run_ios.sh 

prod build:

sh scripts/clean_run_ios.sh -r
