一旦我在代码中尝试这样做

Future<void> loadProducts() async {
  try {
    final offerings = await Purchases.getOfferings();

    if (offerings.current == null) {
      log("No offering found", name: "RevenueCat");
      return;
    }

    final packages = offerings.current!.availablePackages;

    for (final package in packages) {
      log("Product: ${package.storeProduct.title}", name: "RevenueCat");
      log("Price: ${package.storeProduct.priceString}", name: "RevenueCat");
      log("ID: ${package.storeProduct.identifier}", name: "RevenueCat");
    }

  } catch (e) {
    log("Error fetching products: $e", name: "RevenueCat");
  }
}

在我的物理设备上运行时，出现如下错误：

我快要崩溃了 🥹，因为显然一切都已正确配置并连接好

• 在设备上使用Apple Connect沙箱账户登录，设备为iPhone 15 Pro，iOS 26.3 在此输入图片描述 在此输入图片描述
• RevenueCat中的产品已配置并链接到Apple Connect 在此输入图片描述
• RevenueCat的 Offerings已正确设置，并与在Apple Connect中配置的产品相配套 在此输入图片描述

一切看起来都正确，我不知道错误是什么。

解决方案

当我遇到这个错误时，原因在于尽管我已经设置了Product、Offerings和 Entitlements，但我并没有选中我的Offering（我的名称是“default”，你们的可能是“pro”或“subscription”，或你命名的任意名称）。在该视图的下方有一个名为“Packages”的标签页，你需要选择并将 $rc_ 变量映射到不同平台的包里。
