I'm sending notification to my flutter app through firebase, and notification is shown on the app both when in foreground and in background, but there is no sound on either. Here's the dart file, android manifest and kotlin file I worked on to get notifications to show.
I've tried reinstalling multiple times, tried different emulators and different API levels. It's persisstant. Currently trying on API 30, and the problem still occurs. No errors when I specify channel name through firebase.
