You can upgrade as long as it is signed with the same key and has a larger version number than your native app. Do not forget to keep compatibility with the file system of your current app, since if you use a database, for example, it should be accessed in the same way in your Flutter app.
To be sure, try an upgrade by uploading an alpha version of Google Play and upgrading to your own device.
