Undefined property: stdClass::$total

I am working on adding the product values into the cart and i am using darryldecode Laravel shopping cart. When I try to get the image and total price from the attribute array, I get the error Undefined property: stdClass::$total.

Here is my Controller:

public function cart(Request $request , $id)
{
  // return $request;
  $cart = Cart::add([
    'id' => $request->id,
    "name" => $request->name,
    "crm"  => $request->sku,
    "quantity" => $request->qty,
    "price" => $request->price,
    "attributes" => array(["image" => $request->image] , "total" => $request->price * $request->qty) 
  ]);

  if($cart)
  {
    return redirect()->route('cart');
  }
}

Here is the Cart Controller

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use Cart;

class CartController extends Controller
{
  public function index()
  {
    // return Cart::getContent();
    return View('demo', [ 'cart' => Cart::getContent()]);
  }
}

Here is the view where I try to print the image and total

@foreach($cart as $product)
Name:<td></td>
Price:<td></td>
Quantity:<td></td>
Attributes:<td></td>
@foreach(json_decode($product->attributes) as $details)
Image:<td></td>
Total:<td></td>

@endforeach
@endforeach
