In my project I get assert constraints from one of my entity and I use this value in my front end via Twig.
I faced a problem with the property $maxSize of the File Constraint.

As this property is protected I cannot access it via Twig because the magic method __isset is missing, as I read in twig documentation.

so I propose to add this piece of code to be able to get this value accessible in Twig:

    public function __isset($option)
    {
        if ('maxSize' === $option) {
            return true;
        }

        return parent::__isset($option);
    }

this solution work for sure as I tested it, but my question is why this is not a simple public property as the rest of the File Constraint class properties?
