Fire method has been removed from Laravel 5.8

[mattglover11]

Controllers need to be updated to change the "fire" method to "dispatch" to make it compatible with Laravel 5.8

You can extend the facade to make it use dispatch in stead of fire.

<?php
namespace App\Facades;
use Illuminate\Support\Facades\Event as IlluminateEvent;

class Event extends IlluminateEvent
{

    public static function fire($var)
    {
        parent::dispatch($var);
    }
}

then in config/app.php you can do

// "Event" => Illuminate\Support\Facades\Event::class,
 "Event" => App\Facades\Event::class,

worked for me, but after spending 4 hours trying to make it work and adjust it to my needs I realised I needed some extra options and I could better write a forum myself.
What a waste of my time. At least I learned how to extend facades. ;-)
