flutter_payway

Flutter widgets for ABA PayWay checkout, built on dart_payway, which it re-exports.

dependencies:
  flutter_payway: ^2.0.0

Payment method picker

PaywayAcceptablePaymentColumn lists payment methods with their logos. By default it offers cards plus ABA PAY: a KHQR to scan on web and desktop, or a deep link into ABA Mobile on Android and iOS.

import 'package:flutter_payway/flutter_payway.dart';

PaywayAcceptablePaymentColumn(
  value: option,
  onChanged: (value) => setState(() => option = value),
  // optional
  options: const [PaywayPaymentOption.cards, PaywayPaymentOption.abapayKhqrDeeplink],
  labels: const PaywayPaymentLabels(cards: 'កាត'),
)

Paying

Call PayWay from your server, not from the app: the API key is a secret and must not ship inside an app. Your server uses dart_payway (or the PHP SDK) to create the purchase and returns the result to the app:

• abapayKhqrDeeplink: open abapayDeeplink with url_launcher, or show qrString as a QR code.
• other options: load the page from checkoutHtml() in a web view.

Then confirm the payment on your server with checkTransaction or the callback on your return_url. See the dart_payway README.
