Audio_service: Android MediaControl button doesn't appear in the notification mediaplayer

[eAvio]

Which API doesn't behave as documented, and how does it misbehave?
In the notification mediaplayer on android the media control buttons aren't drawn, but still can be pressed. This only happens on a release build made with "flutter build apk".

Minimal reproduction project
Unfortunately I don't know what causes this. Cloned example project from github works. I have the appropriate assets defined in the res folder too.

To Reproduce (i.e. user steps, not code)
I don't know.

Error messages
No error messages

Expected behavior
A notification media player with clearly visible buttons.

This is interesting. Didn't the instructions on shrinking that I provided in the README work? Let me know if not and I'll need to update them.

what happened was that i forgot what that line in app/build.gradle did, and i threw it out when i was modifying the file for production build. My bad. Thank you for your response though :)

@girish54321 For me the problem was that I accidentally removed "shrinkResources false" line app/build.gradle when i was preparing my app for production. Check if you have it.

android {
    compileSdkVersion 28
    ...
    buildTypes {
        release {
            signingConfig ...
            shrinkResources false // ADD THIS LINE
        }
    }
}

Check out the 2. step in the "Android setup" section of the README of this package. Hope this works for you.
