## Usage
* Import

```Dart
import 'package:momo_vn/momo_vn.dart';

• Init

  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,
  orderId: '12321312',
  orderLabel: 'Label để hiển thị Mã giao dịch',
  merchantnamelabel: "Tiêu đề tên cửa hàng",
  fee: 0,
  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);
  }
