Question

我在Flutter应用程序中介绍了OneSignal，但在Flutter中不起作用！我无法建立iPhone ...

我想创建一个推送通知功能。我查看了正式文件，照原样完成了。

参考：

我的代码：

void main() async {
  FirebaseAnalytics analytics = FirebaseAnalytics();
  FirebaseAnalyticsObserver observer = FirebaseAnalyticsObserver(analytics: analytics);

  void _handleNotificationReceived(OSNotification notification) { 

  }

  OneSignal.shared.setNotificationReceivedHandler(_handleNotificationReceived);

  OneSignal.shared.init(
    "ID", 
    iOSSettings:
    {
    OSiOSSettings.autoPrompt: false,
    OSiOSSettings.inAppLaunchUrl: true
    }
  );

  OneSignal.shared.setInFocusDisplayType(OSNotificationDisplayType.notification);

  OneSignal.shared.setNotificationReceivedHandler((OSNotification notification) {
  });

  OneSignal.shared.setNotificationOpenedHandler((OSNotificationOpenedResult result) {
  });

  OneSignal.shared.setPermissionObserver((OSPermissionStateChanges changes) {
  });

  OneSignal.shared.setSubscriptionObserver((OSSubscriptionStateChanges changes) {
  });

  OneSignal.shared.setEmailSubscriptionObserver((OSEmailSubscriptionStateChanges emailChanges) {
registered
  });

Android设备成功收到通知，
但是...

错误代码：

你能帮我吗？
