Structure a Flutter domain data layer by defining abstract entity contracts and Freezed models, adding data model mappings for API responses, implementing repository interfaces, and wiring Hive adapters for local persistence.

The repository pattern in Flutter separates data sources from domain logic by defining repository contracts and provider-driven implementations that map API responses to immutable Freezed domain models.

Implement repository interfaces by creating abstract contracts, then build provider-specific implementations for AniList or MAL, wiring them into the dependency injection system to ensure a clean data flow.

Yes, you need Hive adapters and JSON serialization to enable local persistence. Hive adapters store the Freezed data models locally, while JSON serialization maps the API responses to those domain objects.

Use Freezed models in a Flutter domain architecture when you need immutable entity implementations, JSON serialization, and seamless integration with Hive adapters for local persistence and code generation.

The standard pattern for code generation and barrel exports involves generating Freezed models and Hive adapters, then centralizing the exports through barrel files to maintain a clean domain architecture.
