示例代码

以下是一个完整的示例代码，展示了如何使用maswend_midtrans插件进行支付集成。

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:maswend_midtrans/maswend_midtrans.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  [@override](/user/override)
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final flutterWrapper = MaswendMidtrans();

  [@override](/user/override)
  void initState() {
    super.initState();
    _initSdk();
  }

  void _initSdk() {
    // 监听交易完成事件
    flutterWrapper.onTransactionFinished = (MidtransTransactionStatus status) {
      debugPrint('DART: TRX FINISHED');
      debugPrint('TRX FINISHED with status: $status');

      // 根据交易状态进行相应的处理
      switch (status) {
        case MidtransTransactionStatus.Success:
          debugPrint('Transaction success!');
          break;
        case MidtransTransactionStatus.Pending:
          debugPrint('Transaction status pending');
          break;
        case MidtransTransactionStatus.Invalid:
          debugPrint('Transaction Invalid');
          break;
        case MidtransTransactionStatus.Failed:
          debugPrint('Payment Failed');
          break;
        case MidtransTransactionStatus.Cancelled:
          debugPrint('User cancelling payment flow');
          break;
      }
    };

    // 初始化SDK
    flutterWrapper.initMidtransSdk(
       'ClientKey', 'Merchant_URL',
        isSandbox: true);
  }

  void _setUserDetail()async {
    // 设置用户详细信息
    var userDetail = UserDetailMidtrans()
      ..userFullName = 'Edi Kurniawan'

    await flutterWrapper.setUserDetail(userDetail);
  }

  void _addItemDetail() async{
    // 添加商品详细信息
    var itemDetail = ItemDetailMidtrans()
      ..id = '123'
      ..price = 20000.0
      ..quantity = 2
      ..name = 'Dummy Item';
    await flutterWrapper.addItemDetail(itemDetail);
  }

  void _createTransaction() async{
    // 创建交易请求
    await flutterWrapper.setTransactionRequest('TRX100009', 40000.0);
  }

  void _startPayment() {
    // 开始支付流程
    flutterWrapper.startPayment();
  }

  void _startPaymentWithUserDetail() {
    // 开始支付流程并跳过用户详情输入
    flutterWrapper.startPayment(skipCustomerDetails: false);
  }

  var snapToken = '34df554e-5250-4b37-b2f9-3c213a398007';

  void _startPaymentWithToken() async {
    // 使用Snap Token开始支付
    await flutterWrapper.startPayment(paymentMethod: MidtransPaymentMethod.GoPay,snapToken: snapToken);
  }

  void _startBankTransferPaymentWithToken() async {
    // 使用银行转账方式开始支付
    await flutterWrapper.startPayment(
        paymentMethod: MidtransPaymentMethod.BankTransferPermata,
        snapToken: snapToken);
  }
