Why are `onPushReceived` and `onPushAccepted` events not working in my Flutter app on iOS?

If the onPushReceived and onPushAccepted event listeners are functioning correctly on Android but not on iOS, it is typically because the native iOS part of your application is not configured to pass notification interaction data to the Pushwoosh SDK.

To resolve this, you need to add native code to your project's AppDelegate.swift file to handle the notification response.

1. In your Xcode project, open the ios/Runner/AppDelegate.swift file.
2. Add the following method to your AppDelegate class. If this method already exists, simply add the line Pushwoosh.sharedInstance().handlePushReceived(userInfo) inside it.

override func userNotificationCenter(
  _ center: UNUserNotificationCenter,
  didReceive response: UNNotificationResponse,
  withCompletionHandler completionHandler: @escaping () -> Void
) {
  let userInfo = response.notification.request.content.userInfo

  // Pass the notification payload to the Pushwoosh SDK
  Pushwoosh.sharedInstance().handlePushReceived(userInfo)

  completionHandler()
}

This implementation ensures that when a user taps on a notification, the event is captured and passed to the Pushwoosh SDK, which will then trigger the appropriate listeners (onPushAccepted or onPushReceived) in your Flutter application.
