Cant share Auth::check() in App\Http\Controllers\Controller via view()->share

Question

I want to share in every view Auth::check() result as a $signedIn variable, i found that i can do it via Parent Controller in Laravel. It works good, but it doesn't want to work for Auth::check() - it returns nothing.

Code for a parent Controller

    namespace App\Http\Controllers;

    use Illuminate\Foundation\Bus\DispatchesJobs;
    use Illuminate\Routing\Controller as BaseController;
    use Illuminate\Foundation\Validation\ValidatesRequests;
    use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
    use Illuminate\Support\Facades\Auth;


    class Controller extends BaseController
    {
        use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

        public function __construct()
        {
            view()->share('signedIn', Auth::check());
        }
    }

Code of the view, in which i use $signedIn variable mentioned before

@if($signedIn)

    @include('question.answer-form')

@else

    <div class="alert alert-warning">
        <p>
            <a href="{{ url('login') }}">Sign in</a> in order to answer a question
        </p>
    </div>

@endif

In the constructor of the controller, from which i redirect to the view, i've called a parent constructor - the problem is that it doesn't want to work for Auth::check().

Laravel 5.3v.

You can't access the session or authenticated user in your controller's constructor because the middleware has not run yet.

try that :

public function __construct()
{
     $this->middleware(function ($request, $next) {
          view()->share('signedIn', Auth::check());

          return $next($request);
     });
}
