How to access session from service provider in laravel?
Get the $orders variable in the header.
There is a session in the files, but in the AppServiceProvider
dd(session('item')) = null.

public function boot()
    {
    $orders = Order::where('id',session('item'))->first();
         View::share([
       'orders'=> $orders,
        ]);
    }
