```php

use Ghostwriter\EventDispatcher\EventDispatcher;

use Ghostwriter\EventDispatcher\ListenerProvider;

// Create an event class

final class ExampleEvent

{

}

// Create an Event Listener

final class ExampleEventListener

{

    public function __invoke(ExampleEvent $event): void

    {

        // Handle the event, e.g., print the event class name

        // echo $event::class;

    }

}

// Create a ListenerProvider

$listenerProvider = ListenerProvider::new(); // or new ListenerProvider(Container::getInstance())

// Bind the Listener to the Event

$listenerProvider->listen(ExampleEvent::class, ExampleEventListener::class);

// Create an EventDispatcher

$dispatcher = EventDispatcher::new($listenerProvider); // or new EventDispatcher($listenerProvider)

// Dispatch the Event.

$event = $dispatcher->dispatch(new ExampleEvent());

// Assert the Event is the same as the dispatched Event

assert($event instanceof ExampleEvent);
