如何在flutter中删除应用购买测试中的购买？

import 'package:in_app_purchase/in_app_purchase.dart';

void setupInAppPurchases() {
  final InAppPurchaseConnection connection = InAppPurchaseConnection.instance;
  connection.enablePendingPurchases();

  if (Platform.isAndroid) {
    // 设置沙盒环境
    connection.androidPlatformChannel.setMockResponse(
      'com.example.appsku', // 替换为你的应用的SKU
      BillingResponseWrapper(
        responseCode: BillingResponse.ok,
        debugMessage: 'Mocked response for purchase restored.',
      ),
    );
  } else if (Platform.isIOS) {
    // 设置沙盒环境
    connection.iOSPlatformChannel.setMockResponse(
      'com.example.appsku', // 替换为你的应用的SKU
      TransactionWrapper(
        transactionId: 'mocked-transaction-id',
        transactionReceipt: 'mocked-transaction-receipt',
        purchaseDetails: PurchaseDetails(
          purchaseID: 'mocked-purchase-id',
          productID: 'com.example.appsku', // 替换为你的应用的SKU
          status: PurchaseStatus.purchased,
        ),
      ),
    );
  }
}
