iOS Flutter not getting push notifications

Question

I'm having issues setting up push notifications for iOS on Flutter. Another dev tried adding too - had the same problem.

TL;DR: Can anyone get pushes running on iOS Flutter with clean new build from stable channel?

I followed setup steps described here: https://pub.dev/packages/firebase_messaging

Specifically:

• Generated app ID and push Key in https://developer.apple.com/account/resources/certificates/
• Added info.plist to ios/Runner folder
• Turned on Push capabilities
• Uploaded APNS certificate to Firebase console
• Made sure bundle ID is the same in App / Runner, info.plist and GoogleService-Info.plist

• Added lines in AppDelegate.swift

  if #available(iOS 10.0, *) { UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate }

Pushes aren't coming. Neither when app in background, not at all.

I also tried another step - sending individual push. Send code in CURL looks like this:

curl -i -X POST \
   -H "Content-Type:application/json" \
   -H "Authorization:key=AIza_legacy_key" \
   -d \
'{

  "to": "my_push_token",

  "notification": 
  {"body": "test_body",
   "title": "test_title"
  }, 

  "priority": "high", 

}
' \
 'https://fcm.googleapis.com/fcm/send'

And the response is always this type: - First request is InvalidRegistration - Second and next same calls is NotRegistered

Another person found similar problem this summer and posted on GitHub, but thread was closed: https://github.com/flutter/flutter/issues/30486

p.s. Some things I've tried:

• Used another developer account (100% confirmed pushes are working on another project)
• Used another Firebase account
• Recreated certificates, projects
• Gave to try another developer to setup pushes his own (he also confirmed to be successfull in the past).

Answer 1

Magically things just started working yesterday evening. So first - just try now. If not working - recreate certificates and redo initialization steps. If still not working - pray and retry another day.
