How to Use Prefixed Service In Custom Rule

Since rector/rector version 0.11, it is not possible to use service that previously not prefixed in previous version, for example, you have the following custom rector rule with Symplify\PackageBuilder\Strings\StringFormatConverter dependency:

use Symplify\PackageBuilder\Strings\StringFormatConverter;

final class UnderscoreToCamelCaseVariableNameRector extends AbstractRector
{
    public function __construct(StringFormatConverter $stringFormatter)
    {
        // ...
    }
}

For above example, the Symplify\PackageBuilder\Strings\StringFormatConverter is no longer exists, you can consume via require --dev it:

composer require --dev symplify/package-builder

After that, you need to register the symplify/package-builder's src to service in rector.php:

<?php
// rector.php

use Symplify\PackageBuilder\Strings\StringFormatConverter;

return static function (ContainerConfigurator $containerConfigurator): void {
    // ...

	$services = $containerConfigurator->services();
	$services->set(StringFormatConverter::class);

    // ...
};

Now, the Symplify\PackageBuilder\Strings\StringFormatConverter service will be detected again.
