Return type conflict in UploadedFileInfo

[mmarton]

Hi!

There is a type conflict here:

https://github.com/antishov/StofDoctrineExtensionsBundle/blob/master/Uploadable/UploadedFileInfo.php#L29

the implemented interface returns string|null

https://github.com/doctrine-extensions/DoctrineExtensions/blob/main/src/Uploadable/FileInfo/FileInfoInterface.php#L31

and the used UploadedFile class returns int|false (inherited from SplFileInfo)

https://www.php.net/manual/en/splfileinfo.getsize.php

At the docs there is a part which says:

https://symfony.com/bundles/StofDoctrineExtensionsBundle/current/configuration.html

# Default file info class implementing FileInfoInterface: Optional. By default we provide a class which is prepared to receive an UploadedFile instance.
default_file_info_class: Stof\DoctrineExtensionsBundle\Uploadable\UploadedFileInfo

So this could be an issue on doctrine-extension's side. idk

I don't have any idea how can this be fixed without BC.
