How do you generate event and listeners?

To generate events and listeners in Laravel, you can use the Artisan command-line tool, which simplifies the process. Here is a step-by-step guide:

Step 1: Register the Event and Listeners

First, you need to register your events and listeners in the EventServiceProvider class, which is located in the app/Providers directory. This class contains a $listen property where you map events to their corresponding listeners.

<?php

namespace App\Providers;

use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        'App\Events\OrderShipped' => [
            'App\Listeners\SendShipmentNotification',
        ],
    ];

    /**
     * Register any events for your application.
     *
     * @return void
     */
    public function boot()
    {
        parent::boot();
    }
}

Step 2: Generate Events and Listeners

Once you have registered your events and listeners, you can use the event:generate Artisan command to automatically create the necessary files. This command will generate any events or listeners that are listed in your EventServiceProvider but do not yet exist.

php artisan event:generate

Alternatively, you can generate events and listeners individually using the make:event and make:listener commands. For example:

php artisan make:event OrderShipped
php artisan make:listener SendShipmentNotification --event=OrderShipped

Step 3: Define the Event and Listener Classes

After generating the files, you need to define the event and listener classes. The event class is typically a data container for the event-related data, while the listener class contains the logic to handle the event.

Event Class (OrderShipped.php):

<?php

namespace App\Events;

use Illuminate\Queue\SerializesModels;

class OrderShipped
{
    use SerializesModels;

    public $order;

    /**
