Usage

• Import

import 'package:momo_vn/momo_vn.dart';

 void initState() {
    super.initState();
    _momoPay = MomoVn();
    _momoPay.on(MomoVn.EVENT_PAYMENT_SUCCESS, _handlePaymentSuccess);
    _momoPay.on(MomoVn.EVENT_PAYMENT_ERROR, _handlePaymentError);
    initPlatformState();
  }

• Create data Object

MomoPaymentInfo options = MomoPaymentInfo(
    merchantname: "Tên đối tác",
    merchantcode: 'Mã đối tác',
    appScheme: "1221212",
    amount: 6000000000,

    description: 'Mô tả chi tiết',
    username: 'Định danh user (id/email/...)',
    partner: 'merchant',
    extra: "{\"key1\":\"value1\",\"key2\":\"value2\"}",
    isTestMode: true
);

• Open MoMo application

try {
    _momoPay.open(options);
  } catch (e) {
    debugPrint(e);
  }

• Get result

void _setState() {
    _payment_status = 'Đã chuyển thanh toán';
    if (_momoPaymentResult.isSuccess) {
      _payment_status += "\nTình trạng: Thành công.";
      _payment_status += "\nSố điện thoại: " + _momoPaymentResult.phonenumber;
      _payment_status += "\nExtra: " + _momoPaymentResult.extra;
      _payment_status += "\nToken: " + _momoPaymentResult.token;
    }
    else {
      _payment_status += "\nTình trạng: Thất bại.";
      _payment_status += "\nExtra: " + _momoPaymentResult.extra;
      _payment_status += "\nMã lỗi: " + _momoPaymentResult.status.toString();
    }
  }
  void _handlePaymentSuccess(PaymentResponse response) {
    setState(() {
      _momoPaymentResult = response;
      _setState();
    });
    Fluttertoast.showToast(msg: "THÀNH CÔNG: " + response.phonenumber, timeInSecForIos: 4);
  }

  void _handlePaymentError(PaymentResponse response) {
    setState(() {
      _momoPaymentResult = response;
      _setState();
    });
    Fluttertoast.showToast(msg: "THẤT BẠI: " + response.message.toString(), timeInSecForIos: 4);
  }
