use Skies\QRcodeBundle\Generator\Generator;

class MyController extends AbstractController
{
    public function index(Generator $generator): Response
    {
        $barcode = $generator->generate([
            'code'   => 'Hello World',
            'type'   => 'qrcode',
            'format' => 'svg',

$generator = new Generator();
$barcode = $generator->generate([
    'code'   => 'Hello World',
    'type'   => 'qrcode',
    'format' => 'html',
