Firebase messging crashes the app only in release build

My (Flutter) mobile application uses Firebase messaging and it works fine in debug mode, but when I run/build it in the release mode it crashes upon receiving a message from Firebase. I suspect that onMessage.listen somehow crashes the app. It happens only on Android devices.

Is there anything that I could've missed during the Firebase project setup or within the Android app configuration?

The following error logs are produced upon receiving a message:

E/AndroidRuntime(26859): FATAL EXCEPTION: firebase-iid-executor

The problem was solved by adding code below to /android/app/build.gradle:

...
buildTypes {
        release {
            ...
            shrinkResources false
            minifyEnabled false
        }
    }

and adding code below to /android/gradle.properties:

android.enableR8=false
