To Reproduce

1. Googlepay using pay plugin payment is getting success.

2. Then we are adding google pay token to stripe.
   final token =
   paymentResult['paymentMethodData']['tokenizationData']['token'];
   final tokenJson = Map.castFrom(json.decode(token));
   print(tokenJson);
   print("$token{tokenJson['id']}");
   print("Here the whole data is printing");

   final params = PaymentMethodParams.cardFromToken(
   token: tokenJson['id'],
   );

   //PaymentMethodParams.afterpayClearpay(shippingDetails: ShippingDetails())

   // 3. Confirm Google pay payment method
   await Stripe.instance.confirmPayment(
   clientSecret,
   params,
   );
