Class design
Based on MVPs, common or bloat-prone processing, such as communication and screen transitions, is handled by other classes at the right time.
The lifetime of a Model only lasts within its screen, and persistent data is kept in the Repository.
There is one Presenter for each screen.
As you have more elements on the screen, Presenter tends to get bigger, so we break out the big processing into separate classes to reduce the processing Presenter does directly.
Model and View are also one in the default 1 screen, but split them if the screen is bloated or if the on-screen elements are independent.
Names like UseCase and Repository adopt terminology used in other architectures, such as clean architecture, but are not consistent with clean architecture.
They are designed to reference clean architecture and other architectures, but with the goal of reducing complexity and ease of use.
