Laravel 5.7 solution

public function __construct()
{

$this->middleware(function ($request, $next) {
// fetch session and use it in entire class with constructor
$this->cart_info = session()->get('custom_cart_information');

return $next($request);
});

}

If you want to use constructor for any other functionality or query or data then do all the work in $this->middleware function, NOT outside of this. If you do so it will not work in all the functions of entire class.
