• Payment Creation: Initiate payment transactions.
• Refund Creation: Process refunds for completed transactions.
• Service Creation: Execute various service operations on the POS terminal.

Installation

To utilize this module in your project, follow these steps:

1. Add the module to your project dependencies.
2. Import the POSPaymentModule class.
3. Initialize the module with the IP address and port of the POS terminal.

import 'pos_payment_module.dart';

final posModule = POSPaymentModule(ip: 'terminal_ip_address', port: 1234);

Usage

Connecting to the POS Terminal

await posModule.connect();

Creating a Payment

final paymentResponse = await posModule.createPayment(
  organizationCode: null,
  amount: 100.0,
  clientId: 'client_id',
  idempotenceKeyERN: 'idempotence_key_ern',
);

Creating a Refund

final refundResponse = await posModule.createRefund(
  organizationCode: null,
  amount: 50.0,
  retrievalReferenceNumber: 'reference_number',
  clientId: 'client_id',
  idempotenceKeyERN: 'idempotence_key_ern',
);

Creating a Service Operation

final serviceResponse = await posModule.createService(
  organizationCode: null,
  clientId: 'client_id',
  operationServiceType: OperationServiceType.SOME_TYPE,
  idempotenceKeyERN: 'idempotence_key_ern',
);

Abort operation

Abort operation is not async function, because it has not result data, bool flag is just result of success or unsuccess creation. The result of aborting the operation will be received in the operation that you aborted.

bool stopSuccess = posModule.createAbort(
  organizationCode: null,
  clientId: 'client_id',
  idempotenceKeyERN: 'idempotence_key_ern',
);
