You say
Show me how to map a sign-in use case result to an AuthBloc state using Clean Architecture and functional error handling.
Your agent does
I've implemented the AuthBloc using Clean Architecture. // Presentation: Bloc State Mapping final result = await _signInWithEmail(params); emit(result.fold( (failure) => AuthState.error(failure.message), (user) => AuthState.authenticated(user), )); Tests written using mocktail following the AAA pattern.

About this skill
Professional Flutter Architecture & Development
Building a basic Flutter app is easy; building a production-grade, scalable application that survives long-term maintenance is hard. This skill provides the deep architectural knowledge needed to implement Flutter apps using Clean Architecture and Domain-Driven Design (DDD).
What it does
This skill guides developers through the entire Flutter lifecycle—from initial project structure to App Store deployment. It specializes in:
- Implementing Clean Architecture with distinct Presentation, Domain, and Data layers.
- Robust state management using the BLoC (Business Logic Component) pattern.
- Advanced testing strategies, including Unit, Widget, and native UI testing with Patrol.
- Functional programming in Dart using Either types for predictable error handling.
- Native integrations via MethodChannels and Platform Channels for things like payments or hardware sensors.
Why use this skill?
Unlike generic AI prompting, this skill enforces strict architectural boundaries and best practices (like TDD and Dependency Injection with get_it). It ensures your code is testable, decoupled, and follows the standards used by high-performance mobile engineering teams. It eliminates the "spaghetti code" common in AI-generated Flutter projects by using standardized DTOs, Value Objects, and Auth Facades.
Example Output
The skill produces structured code snippets, dependency injection configurations, and test files using the Arrange-Act-Assert (AAA) pattern, typically involving Dart 3 features like Records and Pattern Matching.
