flutter_app_store_server_receipt_utility 是一个用于在 Flutter 应用中验证应用内购买（In-App Purchase, IAP）收据的插件。它主要用于与 Apple App Store 和 Google Play Store 的服务器进行通信，以验证购买收据的有效性。

以下是如何使用 flutter_app_store_server_receipt_utility 插件的基本步骤：

1. 添加依赖

首先，在你的 pubspec.yaml 文件中添加 flutter_app_store_server_receipt_utility 插件的依赖：

dependencies:
  flutter:
    sdk: flutter
  flutter_app_store_server_receipt_utility: ^1.0.0  # 请使用最新的版本号

然后运行 flutter pub get 来获取依赖。

2. 初始化插件

在你的 Dart 代码中，导入插件并初始化它：

import 'package:flutter_app_store_server_receipt_utility/flutter_app_store_server_receipt_utility.dart';

void initializePlugin() {
  final receiptUtility = FlutterAppStoreServerReceiptUtility();
}

3. 验证 App Store 收据

对于 Apple App Store，你可以使用 verifyAppStoreReceipt 方法来验证收据：

Future<void> verifyAppStoreReceipt() async {
  final receiptUtility = FlutterAppStoreServerReceiptUtility();
  
  // 获取收据数据
  final receiptData = await receiptUtility.getAppStoreReceiptData();
  
  // 验证收据
  final verificationResult = await receiptUtility.verifyAppStoreReceipt(
    receiptData: receiptData,
    sharedSecret: 'YOUR_SHARED_SECRET',  // 你的 App Store Connect 中的共享密钥
  );

  if (verificationResult.status == ReceiptStatus.valid) {
    print('收据验证成功');
  } else {
    print('收据验证失败: ${verificationResult.status}');
  }
}

4. 验证 Google Play 收据

对于 Google Play Store，你可以使用 verifyGooglePlayReceipt 方法来验证收据：

Future<void> verifyGooglePlayReceipt() async {
  final receiptUtility = FlutterAppStoreServerReceiptUtility();
  
  // 获取收据数据
  final purchaseData = await receiptUtility.getGooglePlayPurchaseData();
  final dataSignature = await receiptUtility.getGooglePlayDataSignature();
  
  // 验证收据
  final verificationResult = await receiptUtility.verifyGooglePlayReceipt(
    purchaseData: purchaseData,
    dataSignature: dataSignature,
    packageName: 'YOUR_PACKAGE_NAME',  // 你的应用包名
    productId: 'YOUR_PRODUCT_ID',      // 你的产品ID
  );

  if (verificationResult.status == ReceiptStatus.valid) {
    print('收据验证成功');
  } else {
    print('收据验证失败: ${verificationResult.status}');
  }
}
