Application Events
The application will automatically emit the following events (and intentions) during its lifecycle.
To subscribe to events, you can use direct access to the event listener.
$app->addEventListener(Event::class, function (Event $e) {
var_dump($e);
});
The application instance also supports a more convenient and simple way of registering events using the on() method.
$app->on(function (Event $event): void {
var_dump($event);
});
Starting Intention

class ApplicationStarting<Application>

class ApplicationStopping<Application>
Stopped Event
An Boson\Event\ApplicationStopped event fired after the application has been stopped and the Boson\Event\ApplicationStopping intention has not been cancelled.
