Teams using flutter-layer-based-clean-architecture should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

  • You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

  • You only need a quick one-off answer and do not need a reusable workflow.
  • You cannot install or maintain the underlying files, dependencies, or repository context.

# Layer-Based Clean Architecture

## **Priority: P0 (CRITICAL)**

Standardized separation of concerns and dependency flow using DDD principles.

## Workflow: Add a New Feature Across Layers

1. Define the domain entity with `@freezed` in `lib/domain/entities/`
2. Define the repository interface in `lib/domain/repositories/`
3. Create the DTO in `lib/infrastructure/dtos/` with `fromJson`/`toEntity` mapper
4. Implement the repository in `lib/infrastructure/repositories/`
5. Wire the BLoC/Cubit in `lib/application/` consuming the repository interface
6. Register bindings in `get_it` injection container
7. Build the screen in `lib/presentation/` using `BlocBuilder`

## Structure

```text
lib/
├── domain/ # Pure Dart: entities (@freezed), failures, repository interfaces
├── infrastructure/ # Implementation: DTOs, data sources, mappers, repo impls
├── application/ # Orchestration: BLoCs / Cubits
└── presentation/ # UI: Screens, reusable components
```

## Implementation Guidelines

- **Dependency Flow**: `Presentation -> Application -> Domain <- Infrastructure`. Dependencies point inward.
- **Pure Domain**: No Flutter (Material/Store) or Infrastructure (Dio/Hive) dependencies in `Domain`.
- **Functional Error Handling**: Repositories must return `Either<Failure, Success>`.
- **Always Map**: Infrastructure must map DTOs to Domain Entities; do not leak DTOs to UI.

See [DTO-to-Entity mapping example](references/REFERENCE.md).

- **Immutability**: Use `@freezed` for all entities and failures.
- **Logic Placement**: No business logic in UI; widgets only display state and emit events.
- **Inversion of Control**: Use `get_it` to inject repository implementations into BLoCs.

## Anti-Patterns

- **No DTOs in UI**: Never import a `.g.dart` or Data class directly in a Widget.
- **No Material in Domain**: Do not import `package:flutter/material.dart` in the `domain` layer.
- **No Shared Prefs in Repo**: Do not use `shared_preferences` directly in a Repository; use a Data Source.
