How to define authenticated user in Laravel controller constructor?

Question

Laravel

Found in the documentation that since version 5.3 you can't use the Auth facade to get the authenticated user in the controller's constructor, but only with a Closure-based proxy. But how to do it? Show me with an example. The code below gives an error that the $user object does not exist:
public function __construct(){
$this->user=auth()->user();
}

https://laravel.com/docs/5.3/upgrade "Controllers" section. And it's not all about the façade.
