I currently have an Android app which I'm going to rebuild in flutter. (I would really like to just start with a clean slate in the code base, but don't want to loose installs/current backend Google play subscription integration already set up and associated with the current store listing.)
My question is do I have to add a flutter module to the existing build, or can I start from scratch, rebuild it and then upload the generated flutter (android apk) to the play store, or will it not let me because it is a different package?
If I use the same Package name and Keystore as the original android apk, will Google play allow it?
