Flutter集成Adapty时已加载Paywall但无法展示UI的问题求助

我在Flutter项目中集成Adapty SDK时碰到了一个棘手的问题：已经成功加载到Paywall实例，但调用createPaywallView方法展示UI时直接报错，而且日志里显示hasViewConfiguration: false。我已经在Adapty后台把对应的Paywall设置为“Live”状态了，实在搞不懂问题出在哪，想请各位帮忙分析下。

我的相关代码 #

static Future<AdaptyPaywall?> getPaywallByPlacement(String placementId) async {
  try {
    final result = await Adapty().getPaywall(
      placementId: placementId,
    );
    print("✅ Paywall loaded for placement: $placementId");
    return result;
  } catch (e, stack) {
    print("❌ Failed to load paywall for $placementId");
    print(e);
    print(stack);
    return null;
  }
}

static Future<void> showPaywallUI(
    {required String placementId, String? locale}) async {
  try {
    final paywall = await getPaywallByPlacement(placementId);
    if (paywall == null) {
      print("❌ Paywall not found for placement: $placementId");
      return;
    }
    print("✅ Paywall loaded for placement: $placementId");
    print("里 variationId: ${paywall.variationId}");
    print("📦 hasViewConfiguration: ${paywall.hasViewConfiguration}");
    print("茶 remoteConfig: ${paywall.remoteConfig}");
    print("燐 experimentName: ${paywall.name}");

    final view = await AdaptyUI().createPaywallView(
      paywall: paywall,
      locale: 'en',
    );
    await view.present();
    print("✅ Paywall UI presented for: $placementId");
  } catch (e, stack) {
    print("❌ Failed to present Paywall UI");
    print(e);
    print(stack);
  }
}

运行日志 #

flutter: ✅ Paywall loaded for placement: paywall
flutter: 里 variationId: <<variationid>>
flutter: 📦 hasViewConfiguration: false
flutter: 茶 remoteConfig: null
flutter: 燐 experimentName: Subscription
flutter: ❌ Failed to present Paywall UI
flutter: (code: 2003, message: Server error, detail: HTTPError.backend(GET /sdk/in-apps/<<sdkid>>/paywall-builder/, [2.10.3]: Adapty/HTTPDataResponse.Validator.swift#14, statusCode: 404))

我的观察和疑问 #

从日志能看出来，Paywall的基础信息（variationId、experimentName等）都能正常获取到，但：

• 为什么hasViewConfiguration会是false？我明明在后台配置了Paywall的UI并且设为Live了
• 最终抛出的404服务器错误，是不是和hasViewConfiguration: false直接相关？
• 要怎么调整才能成功展示Paywall的UI呢？
