I’m trying to send notifications with custom sounds based on the type of notification in my Flutter app. While the implementation works fine on Android, I’m having trouble with the iOS part.

I am using the Awesome Notifications package in Flutter to handle notifications across both Android and iOS. While I can successfully implement custom notification sounds on Android, I am facing issues with iOS where no sound is played when a notification is received. If I remove the soundSource parameter, the default notification sound plays without any issues.
