Laravel uses an active records pattern for the models. In this design pattern / architecture. The Model will not know it's columns, before they hit the database. Fillable is not a definition, more of a guard to ensure, you can't overwrite all columns from requests or similar.

In your example your Model, has not been saved in the database and therefor does not have any attributes. If you create the Model with data it will show.

$event = new Event(['title' => 'Your title','start_at' => now(),'end_at' => now()]);
$event->save();
dd($event); // attributes will be 'title', 'start_at' and 'end_at'

Or similar if you fetch the Model, it will also show the attributes, as it will fetch it will read the columns from the database.

dd(Event::find(1)); // attributes will be all columns from the database
