A Psalm plugin for Laravel
First install Psalm in your project, making sure to run --init, then run the following commands:
composer require --dev psalm/plugin-laravel
vendor/bin/psalm-plugin enable psalm/plugin-laravel
Under the hood it just runs https://github.com/barryvdh/laravel-ide-helper and feeds the resultant stubs into Psalm. It also uses a couple of function return type providers, but nothing special.
