I ran to problem with FCM where:
- I run flutter ios app in release mode
- Then code firebase_message token to push notification
- Then Terminate App
- Then push notification using postman (see below)
- Get notification one
- Then push again but get "error": "NotRegistered"
{
"to": "fcm_token",
"priority": "high",
"data": {
"NotificationTitle": "RequestJ",
"NotificationBody": "Request"
},
"content_available": true,
"apns-priority": 5
}
