+\Illuminate\Support\Facades\Event::listen(\Illuminate\Auth\Events\Login::class, function () {});

Configure your rector.php:

<?php

use RectorLaravel\Rector\StaticCall\EventStringToClassConstantRector;
use Rector\Config\RectorConfig;
use Rector\Transform\ValueObject\StringToClassConstant;

return RectorConfig::configure()
    ->withConfiguredRule(EventStringToClassConstantRector::class, [
        new StringToClassConstant('auth.login', 'Illuminate\Auth\Events\Login', 'class'),
    ]);
