Recipes App project will be built using the principles of Clean Architecture – S.O.L.I.D as one single project (not modular) using the MVVM pattern. The general idea is to have the app divided like this

Architecture and Pattern Description

The project, as is using clean architecture will be divided in:

  • Data (Repository) – Remote data source (Retrofit)
  • DI (Dagger hilt dependency injection)
  • UI (View) – MVVM – ViewModels, States, Model Presentation, Mappers

Advantages of Using Clean Architecture

  • Our code will be even more easily testable than with plain MVVM.
  • Our code will be further decoupled (the biggest advantage.)
  • The package structure is even easier to navigate.
  • The project is even easier to maintain.
  • Our team can add new features even more quickly.
