Architecture

The architecture used in this project is MVVM.

We will instantiate the usecases in the VM, where the UI will be collecting data in case a sharedState value is emitted, each usecase will provide us a result from a single feature. The repositories will be handling the source where the data is provided (although in this project we won't be switching from local to remote in any feature). The datasource will access the framework to retrieve the response.

Modularization

The modules are separated by layers, respecting SOLID:

• App Module houses the activites, in a bigger project we could create a module for each feature

• Presentation Module is responsible for exposing data wrapped in entities that UI collects via a sharedFlow in the ViewModel class.

• Domain Module: This has the Domain Module which contains the usecase responsible for enclosing a particular task, repository interfaces, and entities.

• Data Layer: This includes the Data Module which is responsible for providing a single source of data. It implements the repository interface defined in the domain layer.

• Core module: This is divided in two submodules: One for dependency injection and other for the setup of room and api.
