PHP 8.4 - Deprecations

[alessioacella]

I think we need just few updates to make it fully compatible with Php8.4, in my Laravel 11 app i get:

PHP Deprecated:  SimpleSoftwareIO\QrCode\Generator::generate(): Implicitly marking parameter $filename as nullable is deprecated, the explicit nullable type must be used instead in /var/www/vendor/simplesoftwareio/simple-qrcode/src/Generator.php on line 169
