Basics

Syntax

To initiate a payment , call the AlatPaySdk.startPayment method, and specify the required props:

    AlatPaySdk.startPayment(
      context,
      request: PaymentRequest(
      businessId: "****************",
      amount: 100,
      currency: "NGN",
      customer: Customer(
      email: "[e-mail]",
      phone: "09038818841",
      firstName: "Jane",
      lastName: "Doe",
        ),
    ),
      secretKey: "****************",
      onPaymentComplete: (result) {
        Navigator.pop(context);
        ScaffoldMessenger.of(context).showSnackBar(
          SnackBar(
            backgroundColor: Colors.green,
            content: Text("Successful payment ${result?.message}"),
          ),
        );
      },
      onPaymentError: (panic) {
        Navigator.pop(context);
        ScaffoldMessenger.of(context).showSnackBar(
          SnackBar(
            backgroundColor: Colors.red,
            content: Text(panic.toString()),
          ),
        );
      },
    );

It also adds an AlatPayTheme class, which allows you to customize the look and feel of the payment screens.

AlatPayTheme (
  primaryColor: Colors.blue,
  secondaryColor: Colors.blueAccent,
  )

Branding

You have optional branding parameter to replace the AlatPay logo with your own image.

      branding: "assets/images/branding.png",

Events & callbacks

AlatPaySdk.startPayment includes the following callbacks:

• onPaymentComplete: the payment was completed successfully, the call back returns a PaymentResult object
• onPaymentError: the payment failed, the call back returns a String error message, this callback only covers errors during the payment process, network errors, invalid parameters, etc

Errors such as invalid otp, invalid bank details, insufficient funds, etc are handled within the payment flow itself and do not trigger this callback.
