final FlickPayment flickPayment = FlickPayment();

• Initialize the payment with your configuration:

final success = await flickPayment.initialize(
  PaymentConfig(
    customerEmail: 'customer@example.com',
    amount: '500', // Amount in pence (£5.00)
    currency: 'GBP',
    transactionId: 'UNIQUE_ID_${DateTime.now().millisecondsSinceEpoch}',
    apiKey: 'your_apikey',
    redirectUrl: 'https://your-app.com/payment-callback',
  ),
  onPaymentCompleted: (PaymentCompletionResult result) {
    // Handle payment result
    final details = result.responseData;
    final status = result.transactionStatus;

     print('${status}! Reference: ${details.transactionRef}');
  },
);

• Add the payment button to your widget tree:

@override
Widget build(BuildContext context) {
  return Scaffold(
    body: Column(
      children: [
        // Your other widgets...
        flickPayment.createPaymentButton(context),
      ],
    ),
  );
}
