I currently have version 1.0 of my app live on the app store, developed using Cordova. However, I have developed an updated version 2.0 of the same app using Flutter. While the Cordova app is already available in all countries, I would like to introduce the Flutter app version 2.0 gradually, country by country, instead of releasing it simultaneously to all countries. Is it possible to do so?
Please help me with the steps to achieve the above process.
