Find leaking classes that you never use... and get rid of them.
composer require tomasvotruba/class-leak --devPass directories you want to check:
vendor/bin/class-leak check bin srcMake sure to exclude /tests directories, to keep reporting classes that are used in tests, but never used in the code-base.
Many types are excluded by default, as they're collected by framework magic, e.g. console command classes. To exlude another class, e.g. your interface collector, use --skip-type:
vendor/bin/class-leak check bin src --skip-type="App\\Contract\\SomeInterface"
