Custom iOS notifications sound local notifications package Flutter - ios

Question

I'm using Firebase Cloud Messaging to send notifications to my flutter app, and I'm using the flutter_local_notifications package to handle them, but when I tried to change the default notification sound it worked for android but didn't work for iOS, keep in mind that I add the "sound.aiff" to the root of the native iOS project, can anyone show me what I'm missing here, and thanks in advance

Your server administrator will send you the sound name in notification payload which you added in iOS folder. Payload will look like this
{
aps =
{
alert = "notification message";
sound = "example.caf";
};
}
