erreur de syntaxe symfony

Bonjour j'etait entrain de faire mon panier sur symfony
voici mon controller "cartController "

<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class CartController extends AbstractController
{
    /**
     * @Route("/SHOP/cart", name="panier_index")
     */
    public function index(): Response
    {
        return $this->render('cart/index.html.twig', []);
    }

    /**
     * 
     * @Route("/SHOP/panier/add/{id}", name="cart_add)
     */
    public function add($id, Request $request)
    {
        $session = $request->getSession();

        $panier = $session->get('panier', []);

        $panier[$id] = 1;

        $session->set('panier', $panier);

        dd($session->get('panier'));
    }
}

VOILA l'erreur que j'ai eu :

[Syntax Error] Expected Doctrine\Common\Annotations\DocLexer::T_CLOSE_PARENTHESIS, got 'cart_add' at position 38 in method App\Controller\CartController::add() in C:\Users\invit\MonProjetVR\config/routes../../src/Controller/ (which is being imported from "C:\Users\invit\MonProjetVR\config/routes/annotations.yaml"). Make sure to use PHP 8+ or that annotations are installed and enabled.
