Flutter Flamingo Android Studio Generate Signed Bundle missing

Hello

I need to sign my Android app created in Android Studio. I am using Flamingo version Android Studio Flutter on Windows 11.

I need to build app bundle to upload my app to a Google Play Store.

The following pages provides detailed instructions how to sign an app: developer.android.com/studio/publish/app-signing#certificates-keystores

Issue: Using Flamingo version of Android Studio is missing the signing screen:
Build > Generate Signed Bundle/APK - there is no such command.

Instead, I have: Build > Flutter > Build App Bundle

When I do: Build > Flutter > Build App Bundle, the app is not signed.

After I upload the bundle file to google play, I get the message saying that my app bundle needs to be signed.

Could you please fix the issue.

Thank you
