take user id in all views with laravel

first sorry for my english cuz im from spain.
ok the problem is when i try to get the user in all views with appserviceprovider, this is my code

    public function boot() {
   $comprador =Auth::user();

    View::share('comprador', $comprador);}

and next i try to get the item in other view and the result is null

   <div class="col-6 ">
{{dd($comprador)}}
    </div>

and this is the final result
enter image description here

>Solution :

You dont need to declare any variables you have the auth global helper that you can use anywhere. The code in your blade looks like this.

<div class="col-6 ">
  {{ auth()->user() }}
</div>

if you need lets say the name of the user its just auth()->user()->name etc.
