Where can I use Auth::user() in LARAVEL5?

Question

Laravel

how can I use Auth::user() in particular, I need it in AppServiceProvider or in routes

public function boot()
    {
        $userId = Auth::user()->id;
        dd($userId);   
        $categories = Catigories::where('user_id','=',$userId)->get();
        view()->share('categories', $categories);                   
    }

the task is to display a variable for all views and sorted by the authorized user,
the problem is that he does not see Auth::user() Trying to get property of non-object

the problem is that he does not see Auth::user() Trying to get property of non-object

He sees everything perfectly . It's just that the user is not authorized, so it's impossible to get his id. Use Auth::check() first to check.
