Remove null from a nullable Collection, as empty ArrayCollection is preferred instead to keep property/class method type strict and always a collection
use Doctrine\Common\Collections\Collection;
final class SomeClass
{
private $items;
- public function setItems(?Collection $items): void
+ public function setItems(Collection $items): void
{
$this->items = $items;
}
}Configure your rector.php:
<?php
use Rector\Config\RectorConfig;
use Rector\Doctrine\TypedCollections\Rector\ClassMethod\RemoveNullFromNullableCollectionTypeRector;
return RectorConfig::configure()
->withRules([
RemoveNullFromNullableCollectionTypeRector::class,
]);
