Hello, I have recently updated Laravel from 5.0 to 5.2 but it seems the Event handling has changed a bit.

I keep getting this nasty error when I use $event variable in my Listener. Here is the incriminated code:

<?php 

namespace App\Listeners;

use App\Events\UserWasCreated;

use Illuminate\Contracts\Mail\MailQueue;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;

use Lang;

class UserCreated implements ShouldQueue
{
    /**
     * @var Mailer
     */
    private $mailer;
    
    /**
     * Create the event listener.
     *
     * @param Mailer $mailer
     */
    public function __construct( MailQueue $mailer )
    {
        $this->mailer = $mailer;
    }

    /**
     * Handle the event.
     *
     * @param  UserWasCreated  $event
     * @return void
     */

    public function handle( UserWasCreated $event )
    {
            $data = array('password' => $event->user->password, 'username' => $event->user->username, 'email' => $event->user->email);

            $this->mailer->queue('emails.user_created', $data, function($message) use ($data)
            {
                    $message->to($data['email'])->subject(Lang::get('notifications.USER_CREATED_EMAIL_SUBJECT', [], $event->user->lang));
            });
     }
}

Here is the error and stack trace:
