It also discusses using architecture components with the MVVM pattern and clean architecture, including layers for the data, presentation and domain. It provides examples of implementing use cases and repositories, and testing use cases. It emphasizes benefits like testable and collaborative code and outlines best practices like proof of concepts for new learning.
