UrlGeneratorReferenceTypeRector

Replace the magic reference value of UrlGeneratorInterface::generate() with a UrlGeneratorInterface constant

 use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

 class SomeController
 {
     public function run(UrlGeneratorInterface $urlGenerator)
     {
-        return $urlGenerator->generate('homepage', [], true);
+        return $urlGenerator->generate('homepage', [], UrlGeneratorInterface::ABSOLUTE_URL);
     }
 }

Configure your rector.php:

<?php

use Rector\Config\RectorConfig;
use Rector\Symfony\Routing\Rector\MethodCall\UrlGeneratorReferenceTypeRector;

return RectorConfig::configure()
    ->withRules([
        UrlGeneratorReferenceTypeRector::class,
    ]);
