Flutter plugin for Monnify SDK

pub package

Getting Started

To use this plugin, add monnify_payment_sdk as a dependency in your pubspec.yaml file.

How to use

This plugin exposes two APIs:

1. Initialize

Initialize the plugin. This should be done once, preferably in the initState of your widget.

import 'package:monnify_payment_sdk/monnify_payment_sdk.dart';

class _MyAppState extends State<MyApp> {


  late Monnify? monnify;

  void initState() {
    monnify = await Monnify.initialize(
      applicationMode: ApplicationMode.TEST,
      apiKey: 'YOUR API KEY',
      contractCode: 'YOUR CONTRACT CODE',

2. Initialize Payment

Create an object of the Transaction class and pass it to the initializePayment function

Future<void> initializePayment() async {
  final amount = '20.00';
    final paymentReference = 'YOUR PAYMENT REFERENCE';

    final transaction = TransactionDetails().copyWith(
      amount: amount,
      currencyCode: 'NGN',
      customerName: 'Customer Name',
      customerEmail: '',
      paymentReference: paymentReference,
      // metaData: {"ip": "", "device": "mobile"},
      // paymentMethods: [PaymentMethod.CARD, PaymentMethod.ACCOUNT_TRANSFER, PaymentMethod.USSD],
      /*incomeSplitConfig: [SubAccountDetails("MFY_SUB_319452883968", 10.5, 500, true),
          SubAccountDetails("MFY_SUB_259811283666", 10.5, 1000, false)]*/

    try {
      final response =
          await monnify?.initializePayment(transaction: transaction);
      } catch (e) { 
        // handle exceptions in here.

Optional params: Payment Methods specify transaction-level payment methods. Sub-Accounts in incomeSplitConfig are accounts that will receive settlement for the particular transaction being initialized. MetaData is map with single depth for any extra information you want to pass along with the transaction.

The TransactionResponse class received after sdk is closed contains the below fields

String paymentDate;
double amountPayable;
double amountPaid;
String paymentMethod;
String transactionStatus;
String transactionReference;
String paymentReference;
String currencyCode;

** Note: No TransactionResponse is returned on iOS dev if a user closes the Modal
