How to use this in Symfony 4.4 about notification-bundle HOT 3 CLOSED

Now I got this error, can anyone of you please help me.
I have changed in the Entity added

@Notifiable(name="user")

bind notification bundle inside services.yaml

bind:
            Mgilet\NotificationBundle\Manager\NotificationManager : "@mgilet.notification"
mgilet.twig_extension:
        class: Mgilet\NotificationBundle\Twig\NotificationExtension
        arguments: ['@mgilet.notification', '@security.token_storage', '@twig', '@router']

Inside controller added following below-mentioned function

public function sendNotification(\Mgilet\NotificationBundle\Manager\NotificationManager $manager)
    {
        $notif = $manager->createNotification('New Test');
        $notif->setMessage('Test');
        $notif->setLink('http://symfony.com/');
        $manager->addNotification([$this->getUser()], $notif, true);

        return $this->redirectToRoute('currencies');
    }

What else is missing here ?

HI @easternmayurt this bundle is not yet compatible with SF4.4, it still use deprecated classes like Twig_SimpleFunction.
If you want to use it with SF4.4 you will have to upgrade the TwigExtension class and probably other classes.
Pull Request is welcomed

Thanks for the reply @emulienfou, I will trying to fix it if you can help me out, where I need to maily, because as I am new with the SF so its a bit time taken process to check everything and upgrade. I appreciate if you just let me know what are the main libraries which I need to upgrade.
