Need to release another flutter android app from existing code

Question

I am having issues with my existing android app in playstore and even i lost my JKS file of that app. So i am planning to release a new app with same code. What are the things i have to update like applicationID, package name and so on

Answer 1

I think you don't have to change much things just the things like

1. application id
2. package name of the app

because these are only things which uniquely identifies the app in the playstore.
