Pedromneto97 Custom Skills Flutter Data Layer

Flutter Data Layer (summary)

Purpose: Short, opinionated defaults and pointers for implementing the data layer in a Flutter Clean Architecture app.

Defaults

• HTTP client: dio
• Serialization: json_serializable (codegen)
• Error handling: Only throw mapped/domain errors (example: 401 -> InvalidCredentialsException); rethrow unknown errors so callers can decide.

Details and examples are moved to the references/ docs and templates/ examples in this skill:

• Detailed repository & networking guidance: references/datasource.md
• Model & json_serializable guidance: references/model.md
• Working code templates: templates/

Rename guidance

• If an application only uses a remote source, prefer naming the component and folder repository (and use Repository suffix) instead of datasource. Templates use repository for that case.

Quick prompts

• "Scaffold a User model using json_serializable and a UserRepositoryImpl using dio that maps 401 -> invalid credentials."
• "Generate DTO tests: fromJson, toJson, and toEntity() round-trip for UserResponse."
