            try {
              Map<String, dynamic> body = {
                'amount': calculateAmount(amount: amount),
                'currency': currency,
                'payment_method_types[]': 'card'
              };
              var response = await http.post(
                Uri.parse('https://api.stripe.com/v1/payment_intents'),

              if (response.statusCode == 200) {
                var decode = jsonDecode(response.body);
                logger.e(decode);
        
                id = decode['id'];
                return decode;
              }
            } catch (e) {
              logger.e(e, "error charging user");
            }
           
          }
        
          calculateAmount({amount}) {
            logger.e(amount.round());
            final a = (int.parse(amount.toString())) * 100;
            logger.e(a.toString());
            update();
