Flutter

Requirements  (opens in a new tab)

If you don't know how to get your API credentials in the Dashboard, please consult Getting your API Key (opens in a new tab) documentation.

To Get Started with this SDK, Make sure you have a Flutter application ready. Also make sure you have subscribed to the various payment providers you want.

Dependencies. See the current version on pub (opens in a new tab)

flutter_payunit: ^0.0.5

Get package using:

terminal

flutter pub get flutter_payunit

Using the SDK (opens in a new tab)

Import PayUnit in the required widget

import 'package:flutter_payunit/flutter_payunit.dart';

Use the pay button as a widget.

PayUnitButton(
 
	apiUsername: "<Your apiuser>",
 
	apiPassword: "<Your apiPassword>",
 
	apiKey: "<Your apiKey>",
 
	mode: 'live', // live or sandbox
 
	paymentCountry: '<Transaction country>'
 
	notifyUrl: "<Your notification url>",
 
	returnUrl: "<Your return url>",
 
	totalAmount: "<Your transaction amount>",
 
	currency:"XAF",
 
	buttonTextColor: Colors.white,
 
	buttonText: "Pay now",
 
	width: double.infinity
 
	color: Colors.orange
 
	actionAfterProccess: (transactionId, transactionStatus) {
		
		// a callback that has both transaction id and transaction status
 
		if(transactionStatus == "SUCCESS"){
			// Handle successful transaction             
		}else if(transactionStatus == "FAILED"){
			// Handle failed transaction             
		}
 
	},
 
),

Then in your app a PayUnit button will appear. When clicked, performs the actual payment. Note, the transactionId is automatically generated. You can access it in the actionAfterProcess callback of the PayUnitButton.
