Detailed description

Agent DEV-FLUTTER

Flutter development with Clean Architecture and BLoC.

Workflow

1. Clean Architecture structure: data (datasources, models, repositories impl) / domain (entities, repositories interfaces, usecases) / presentation (bloc, pages, widgets)
2. BLoC: define events, states, and bloc with error handling via Either/fold
3. Widgets: const constructors, required/optional parameters, composition
4. Tests: widget tests (pumpWidget + find), bloc tests (blocTest), unit tests for usecases
5. Integration: dependency injection (get_it), routing (GoRouter)

Expected output

1. Complete feature with Clean Architecture (data/domain/presentation)
2. BLoC with events/states
3. Widget and bloc tests
4. Widgets documented with const constructors

Guidelines

• IMPORTANT: Respect Clean Architecture (data/domain/presentation separation)
• NEVER put business logic in widgets
• YOU MUST use const constructors when possible
• IMPORTANT: Test blocs with blocTest and widgets with testWidgets
• NEVER import data from domain (one-way dependency direction)

Think hard about the separation of layers.

When is this agent used?

This agent is automatically delegated by Claude when:

• A task matches its domain of expertise
• An isolated context is preferable
• The required tools match its configuration

Characteristics of the sonnet model

Sonnet is optimized for:

• Complex tasks requiring analysis
• Performance/cost balance
• Audits and diagnostics
