I have been trying to get firebase push-notification in my app. I have tried everything on the internet but couldn't find solution. I have been receiving notification in background, but when App is in foreground I am unable to get the notification. But when I print the userInfo in "didReceiveRemoteNotification" I get the message in console Any help would be appreciated.
