              showLockpin:
                  false, // Show the lockpin field for the user if the voucher requires it
              onLongswipeSubmit: (code) async {
                var amount =
                    100.0; // You can prefill this amount based on the value you want to charge
                await redeemVoucher(code, amount);
              },
            ),

import 'package:longswipe/longswipe.dart';
DynamicCheckoutForm(
              onVoucherSubmit: (voucherCode) async {
                // An example to verify the voucher code
                // This can be useful to check if the voucher is valid
                // before proceeding with the payment
                // Or to show them a preview of the voucher details
                // And possibly a section to enter the lockpin if required
                await verifyVoucher(voucherCode);
              },
