Foundations of Clean Architecture

Explain the dependency rule and the flow of data between layers in Clean Architecture.

Define and implement the core shared components of the architecture, such as base UseCase and Failure classes.

Define domain entities and use cases for a single application feature.

Create repository interfaces (abstract classes) in the domain layer.

Implement repository interfaces in the data layer, connecting to data sources.

Implement a remote data source to fetch data from a network API using Dio.

Implement a local data source for caching data to enable offline access.

Connect use cases to BLoC/Cubit classes to bridge domain logic with the presentation layer.
