Create a file called pre-commit in the .git/hooks/ directory.

Open the pre-commit file in a text editor and paste the following code:

#!/bin/sh

flutter pub run flutter_lints
if [ $? -ne 0 ]; then
  echo "Aborting commit. Fix the linter errors/warnings above and try again."
  exit 1
fi

This script will run the Flutter linter whenever you attempt to commit changes.

Save and close the pre-commit file.

Make the pre-commit file executable by running the following command in your terminal:

chmod +x .git/hooks/pre-commit

Now, whenever you try to commit changes, the pre-commit hook will run the Flutter linter and abort the commit if any errors or warnings are found. This helps ensure that your code follows consistent style guidelines and is free from common issues before committing it to version control.
