[SOLVED] FCM notifications not showing on iOS lock screen

FCM notifications not showing on iOS lock screen

I googled a bunch but can not find a comprehensive answer. I am getting my token like this

final notificationSettings = await FirebaseMessaging.instance.requestPermission(
      alert: true,
      announcement: true,
      badge: false,
      provisional: false,
      sound: true
    );

final token = await FirebaseMessaging.instance.getToken();

and send my notifications with python firebase messaging

notification = messaging.Notification(
    'Title',
    'Text'
)

message = messaging.Message(
    notification=notification,
    token=token    
)

messaging.send(message)

The notification arrives, but only in the iPhone notification center. It does not show on the lock screen like all other messages. Do I need to feed in some setting in the app to enable this? I found that the provisional flag (initially I had it as true) triggers this behavior

but I have reset it to false and still my notifications do not show on the lock screen...

Solution

So, what I had to do was to DELETE the app and rebuild. This would erase all previous settings, a new token will be created and with the new permission parameters the notifications will show on the lock screen.
