Usage

Generating Individual QR Code

import 'package:khqrcode/khqrcode.dart';

final individualInfo = IndividualInfo(
  bakongAccountId: 'receivekhqr@dvpy',
  accountInformation: "021550815",
  merchantName: 'M Sovan',
  acquiringBank: 'DVPAY',
  expirationTimestamp: DateTime.now().add(Duration(minutes: 15)).millisecondsSinceEpoch,
  merchantCity: 'Phnom Penh',
  currency: KHQRDataConst.currency['khr']!,
  amount: 1,
);

final bakongKhqr = BakongKHQR();
final result = bakongKhqr.generateIndividual(individualInfo);

if (result.isSuccess) {
  print('QR Code: ${result.data!.qr}');
  print('MD5: ${result.data!.md5Hash}');
}

Generating Merchant QR Code

final merchantInfo = MerchantInfo(
  acquiringBankName: "DVPAY",
  merchantId: "234234234",
  bakongAccountId: 'receivekhqr@dvpy',
  merchantName: 'FLick Coffee',
  merchantCity: 'Phnom Penh',
  currency: KHQRDataConst.currency['khr']!,
  amount: 1,
);

final result = bakongKhqr.generateMerchant(merchantInfo);

Decoding and Verifying QR Code

// Verify QR code
var verification = BakongKHQR.verify(qrString);
if (verification.isValid) {
  print("QR is valid");
}

// Decode QR code
var decodedData = BakongKHQR.decode(qrString);
if (decodedData.isSuccess) {
  print('Decoded data: ${decodedData.data!.toJson()}');
}
