Architecture & state management

State management: Bloc (flutter_bloc). Every screen is driven by a Bloc: the UI sends events, the Bloc emits immutable states, and widgets simply rebuild from the current state. Business logic never lives inside widgets.
Layered architecture: Clean Architecture split into presentation (screens, widgets, Blocs), domain (entities, use cases, repository contracts) and data (repository implementations, remote API and local storage sources).
Data & networking: Repositories wrap the REST API so Blocs never talk to HTTP directly. Responses are mapped into typed models, and errors are turned into clear UI states (loading, success, empty, failure).
Maintainability: Dependency injection wires the layers together, which keeps features isolated, makes Blocs and repositories easy to unit test, and lets new features ship without touching unrelated code.
