The Laravel Config Checker package by Chris Di Carlo scans your codebase to verify if config keys are correctly defined in your config files. This helps ensure that all configuration values referenced in the code exist, helping you to prevent missing or undefined config errors.
Once installed, you can run php artisan config:check, which will scan your app and display any errors in a table with information on the location and missing reference.
View the GitHub repo for complete details on the package.
