{
- public function foo($condition, $value)
+ public function foo($condition, $value): string;
{
if ($value) {

}
return strtoupper($value);
}

<?php
use Rector\Config\RectorConfig;
use Rector\TypeDeclaration\Rector\ClassMethod\StringReturnTypeFromStrictStringReturnsRector;
return RectorConfig::configure()
->withRules([
StringReturnTypeFromStrictStringReturnsRector::class,
