Apple Pay 按钮未显示在真实设备中但同时显示

Question

我在 flutter 应用程序中使用 pay 插件我使用默认的 configjsonfile 用于 apple pay。 而且我还设置了以下

1. 在苹果控制台中添加 SandBox 测试器
2. 通过设备中的沙盒测试器登录
3. 在钱包应用程序中添加信用卡

仍然没有显示苹果支付按钮。

这是苹果按钮代码

final paymentItems = [
      const PaymentItem(
        label: 'Total',
        amount: '99.99',
        status: PaymentItemStatus.final_price,
      )
    ];



 ApplePayButton(
                      paymentConfiguration:
                          PaymentConfiguration.fromJsonString('''{

                      type: ApplePayButtonType.buy,
                      margin: const EdgeInsets.only(top: 15.0),
                      onPaymentResult: onApplePaymentResult,

您是否按照这些步骤注册了 Apple Merchant ID、创建了 Apple Pay 证书并与 Xcode 集成？
