How to change package name on build (Flutter)?

Question

Python

Is it possible to somehow change the name of the package when building the application or make different package names in debug mode and when building?
It's just that I have a ready-made application on my phone, and it also has a version for debugging. And the project itself on the laptop is located in two folders, with different package names. Therefore, when releasing, you constantly have to copy a certain folder from the debug to the release. Is it possible to fit this into one folder?
