Usage 🔨

Make a payment

A simple example of how to compute a USSD payment with QOSIC

final qosic = QosicDart(
  moovKey: 'XXXXXXXXXx',
  mtnKey: 'XXXXXXXXXX',
  username: 'XXXXXXXXXX',
  password: 'XXXXXXXXX',
);

final transactionRef = await qosic.pay(
    network: QosicNetwork.mtn,
    phoneNumber: 'XXXXXXXX', /// precedeed by the country code. ex: 229XXXXXXXX
    amount: '1',
  );

Timer.periodic(
    const Duration(
      seconds: 10, /// feel free to give your own second to wait
                   /// but I will advice you between 7 and 10 secs
    ),
    (timer) async {
      final status = await qosic.getPaymentStatus(
        transactionReference: transactionRef!,
        network: QosicNetwork.mtn,
        country: QosicCountry.benin,
      );

      if (status == QosicStatus.successfull || status == QosicStatus.failed) {
        timer.cancel();
        if (status == QosicStatus.successfull) {
          log("Success for payment");
        } else {
          log("Payment failed");
        }
      }
    },
);

Continuous Integration 🤖

Qosic Dart comes with a built-in GitHub Actions workflow powered by Very Good Workflows but you can also add your preferred CI/CD solution.

Out of the box, on each pull request and push, the CI formats, lints, and tests the code. This ensures the code remains consistent and behaves correctly as you add functionality or make changes. The project uses Very Good Analysis for a strict set of analysis options used by our team. Code coverage is enforced using the Very Good Workflows.
