    secretKey: '....',
    email: '...',
    amount: 15 * 100,
    currency: PaystackCurrency.ngn,
    channel: [
        PaystackPaymentChannel.mobileMoney,
        PaystackPaymentChannel.card,
        PaystackPaymentChannel.ussd,

        PaystackPaymentChannel.qr,
        PaystackPaymentChannel.eft,
    ],
);

2. Initialize the transaction with the above transaction request.

final initializedTransaction = await PaymentService.initializeTransaction(request);

if (!initializedTransaction.status) {
    ScaffoldMessenger.of(context).showSnackBar(SnackBar(
        backgroundColor: Colors.red,
        content: Text(initializedTransaction.message),
    ));

    return;
}

3. Open the payment modal to accept payment

final response = await PaymentService.showPaymentModal(
    context,
    transaction: initializedTransaction,
    // Callback URL must match the one specified on your paystack dashboard,
    callbackUrl: '...'
).then((_) async {
    return await PaymentService.verifyTransaction(
        paystackSecretKey: '...',
        initializedTransaction.data?.reference ?? request.reference,
    );
});

print(response); // Result of the confirmed payment
