完整示例代码

以下是完整的示例代码，展示了如何在Flutter应用中集成Transbank支付功能。

import 'package:flutter/material.dart';
import 'package:transbank/transbank.dart'; // 假设已经安装了Transbank插件

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  Future<void> _initiateTransaction() async {
    // 初始化Transbank支付
    final transaction = await Transbank.initiateTransaction(
      amount: 10000, // 支付金额
      buyOrder: '123456', // 订单号
      sessionId: 'session123', // 会话ID
      returnURL: 'http://localhost:8080/payment_return', // 返回URL
    );

    if (transaction.status == TransactionStatus.approved) {
      // 处理成功情况
      print('支付成功');
    } else {
      // 处理失败情况
      print('支付失败');
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            const Text(
              '你已经点击按钮次数:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ),
      bottomNavigationBar: BottomAppBar(
        child: Row(
          mainAxisAlignment: MainAxisAlignment.spaceEvenly,
          children: [
            ElevatedButton(
              onPressed: _initiateTransaction,
              child: Text('发起支付'),
            ),
          ],
        ),
      ),
    );
  }
}

说明

1. 导入插件：

   import 'package:transbank/transbank.dart';
   

   确保已经在pubspec.yaml文件中添加了Transbank插件依赖。

2. 初始化Transbank支付：

   final transaction = await Transbank.initiateTransaction(
     amount: 10000, // 支付金额
     buyOrder: '123456', // 订单号
     sessionId: 'session123', // 会话ID
     returnURL: 'http://localhost:8080/payment_return', // 返回URL
   );
   

3. 处理支付结果：

   if (transaction.status == TransactionStatus.approved) {
     print('支付成功');
   } else {
     print('支付失败');
   }
