Signing a Flutter App with Google Play Console

Question

I have problems in uploading a standard app on google play. I get following error:

You uploaded an APK or Android app bundle that was signed in debug mode. Upload an APK or Android app bundle that was signed in release mode. Learn more about signing.

I am not sure what I was doing wrong. I went to Build -> Flutter -> Build App Bundle

Please read Signing the app . It clearly says:

To publish on the Play Store, you need to give your app a digital signature. Use the following instructions to sign your app.

On Android, there are two signing keys: deployment and upload. The end-users download the .apk signed with the 'deployment key'. An 'upload key' is used to authenticate the .aab / .apk uploaded by developers onto the Play Store and is re-signed with the deployment key once in the Play Store.
