示例代码

以下是一个完整的示例，展示了如何在Flutter应用中使用bundle_rave_pay插件进行支付集成：

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

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

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

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

class _MyAppState extends State<MyApp> {
  var result;

  [@override](/user/override)
  void initState() {
    super.initState();
    // 初始化插件状态
    initPlatformState();
  }

  // 生成随机字符串
  String _randomString(int length) {
    var rand = new Random();
    var codeUnits = new List.generate(
        length,
            (index){
          return rand.nextInt(33)+89;
        }
    );

    return new String.fromCharCodes(codeUnits);
  }

  // 初始化插件状态
  Future<void> initPlatformState() async {
    try {
      // 构建卡片信息
      var cardBody = {
        "amount": "250",
        "cvv": "564",
        "cardExpiry": "09/22",
        "cardNumber": "5531886652142950",
        "saveCard": "true",
        "country": "NG",
        "currencyCode": "NGN",
        "email": "hashilekky@gmail.com",
        "firstName": "Oluwaleke",
        "lastName": "Fakorede",
        "transactionReference": _randomString(12),
        "isLive": "false",
        // 更新密钥后运行应用
        "publicKey": "FLWPUBK_TEST-85cf4d8da93192c75d63ca7978592de2-X",
        "encryptionKey": "FLWSECK_TEST24303b8618e7",
        "narration": "Bundle Wallet Technology Ltd",
        "paymentMethod": "card",
      };

      // 初始化支付
      result = await BundleRavePay.initializePayment(cardBody);

      if (result != null && result['status'] == 'success') {
        print("PAYMENT RESPONSE JSON IS SUCCESSFUL");
        print(result);
      } else {
        print("NOT JSON");
        print(result);
      }
    } on PlatformException {
      print('Failed to get platform version.');
    }

    if (!mounted) return;

    setState(() {
      // _platformVersion = platformVersion;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: TextButton(
            child: Text('点击进行支付'),
            onPressed: () => initPlatformState(),
          ),
        ),
      ),
    );
  }
}

说明

1. 导入必要的库：

   import 'package:flutter/material.dart';
   import 'dart:async';
   import 'dart:math';
   import 'package:flutter/services.dart';
   import 'package:bundle_rave_pay/bundle_rave_pay.dart';
   

2. 初始化插件状态：

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

3. 生成随机字符串：

   String _randomString(int length) {
     var rand = new Random();
     var codeUnits = new List.generate(
         length,
             (index){
           return rand.nextInt(33)+89;
         }
     );
   
     return new String.fromCharCodes(codeUnits);
   }
   

4. 构建卡片信息：

   var cardBody = {
     "amount": "250",
     "cvv": "564",
     "cardExpiry": "09/22",
     "cardNumber": "5531886652142950",
     "saveCard": "true",
     "country": "NG",
     "currencyCode": "NGN",
     "email": "hashilekky@gmail.com",
     "firstName": "Oluwaleke",
     "lastName": "Fakorede",
     "transactionReference": _randomString(12),
     "isLive": "false",
     "publicKey": "FLWPUBK_TEST-85cf4d8da93192c75d63ca7978592de2-X",
     "encryptionKey": "FLWSECK_TEST24303b8618e7",
     "narration": "Bundle Wallet Technology Ltd",
     "paymentMethod": "card",
   };
   

5. 初始化支付：

   result = await BundleRavePay.initializePayment(cardBody);
   

6. 处理支付结果：

   if (result != null && result['status'] == 'success') {
     print("PAYMENT RESPONSE JSON IS SUCCESSFUL");
     print(result);
   } else {
     print("NOT JSON");
     print(result);
   }
