This core package serves as the foundational shared library for the Flutter News App Full Source Code Toolkit. It defines the common language and data structures—including models for news content, user data, and remote configurations—that ensure consistency and accelerate development across the Flutter mobile app, web dashboard, and Dart Frog backend API.
This package provides a centralized and version-controlled set of shared code artifacts, categorized as follows:
-
Data Models: A comprehensive suite of immutable, serializable Dart classes that represent all data entities within the ecosystem. This includes everything from core content (
Headline,Source) to user data (User) and remote configurations (RemoteConfig). These models act as the strict data contract between the clients and the backend. -
Enumerations: A collection of strongly-typed enums that define controlled vocabularies for application states, types, and categories (e.g.,
ContentStatus,UserRole,AccessTier). This eliminates the use of "magic strings" and ensures compile-time safety. -
Utilities & Exceptions: Common helper functions (e.g.,
DateTimeConverter) and a standardized hierarchy ofHttpExceptionclasses. This ensures consistent error handling and data serialization across all packages. -
Test Fixtures: A rich set of predefined sample data for all core models. This accelerates unit and integration testing by providing a consistent and realistic dataset for developers working on any part of the system.
This core package is an integral part of the Flutter News App Full Source Code Toolkit. For comprehensive details regarding licensing, including trial and commercial options for the entire toolkit, please refer to the main toolkit organization page.
