Flutter: FCM not sending notifications on android release

Fcm notifications used to work like a charm but in my last 2 releases, they do not work in any way. I do not have my app released to the App Store yet so I am not sure if the problem is about the whole project or just about android. I am not really sure where the problem is.

this is my flutter doctor output:

    you have to register release sha-1 key to firebase console. on terminal write cd android then gradlew signingreport this command will show you your keys. register the key that says release sha-1 and it will work.
