Syfmony 5 support

[toooni]

Fixed everything to support symfony 5.x and the upcoming sonata/admin 4.x versions.

Is there any provision to merge this pull request soon.

Hi @bhaktaraz

Thank you for the Pull Request.

Why not also using Autowiring for the Translator in \Pix\SortableBehaviorBundle\Controller\SortableAdminController ?

$translator = $this->get('translator');

[toooni]

@TheFox, yeah, sure, this would make sense. But this can easily be another PR since this one is focused on migrating to symfony 5. Using DI for the translator is an optional change here.

I am also not sure if it will ever get merged. This PR is more than a year old and we're "living" off our fork atm.

@nicolasricci Can you please take a look?

@ottaviano merge this please!

@spolischook, I'm not a maintainer of this repo, btw I'm waiting too for this PR :D

Sonata admin officially migrated to runroom-packages/sortable-behavior-bundle, try it instead (Symfony 5 already supported).
