## How to use
 * Sample code : [laravel-filemanager-demo-events](https://github.com/UniSharp/laravel-filemanager-demo-events)
 * To use events you can add a listener to listen to the events.

Snippet for `EventServiceProvider`

```php
    protected $listen = [
        ImageWasUploaded::class => [
            UploadListener::class,
        ],
    ];
    ```

The `UploadListener` will look like:

```php
    class UploadListener
    {
        public function handle($event)
        {
            $method = 'on'.class_basename($event);
            if (method_exists($this, $method)) {
                call_user_func([$this, $method], $event);
            }
        }

public function onImageWasUploaded(ImageWasUploaded $event)
        {
            $path = $event->path();
            //your code, for example resizing and cropping
        }
    }
    ```

* Or by using Event Subscribers

Snippet for `EventServiceProvider`

```php
    protected $subscribe = [
        UploadListener::class
    ];
    ```

The `UploadListener` will look like:

```php
    public function subscribe($events)
    {
        $events->listen('*', UploadListener::class);
    }

public function handle($event)
    {
        $method = 'on'.class_basename($event);
        if (method_exists($this, $method)) {
            call_user_func([$this, $method], $event);
        }
    }

public function onImageWasUploaded(ImageWasUploaded $event)
    {
        $path = $event->path();
        // your code, for example resizing and cropping
    }

public function onImageWasRenamed(ImageWasRenamed $event)
    {
        // image was renamed
    }

public function onImageWasDeleted(ImageWasDeleted $event)
    {
        // image was deleted
    }

public function onFolderWasRenamed(FolderWasRenamed $event)
    {
        // folder was renamed
    }
    ```
