Install parse failed no certificate

Hi, Team

We are migrating Cordova/PhoneGap application to Flutter framework. When we are releasing the Cordova app, we are releasing as Signed App Bundle.
When we are trying to release Flutter app, for testing the app upgrade like installing the Flutter app on top of Cordova app, we are getting the Signature issue even if we have used the same key store file.
Error says …base.apk is signed using APK signature schema V2, but no such signature was found. Signature stripped?
But When sign the APK using apksigner I can enable V1 --v1-signing-enabled true then able to install the flutter app APK on top of Cordova app. But how can I do this in signing the app bundle?
