Flutter Architecture — Feature-First Skill

This skill defines how to design, structure, and implement Flutter applications using the recommended layered architecture with feature-first file organization.

It is state management agnostic: the business logic holder in the UI layer may be named ViewModel, Controller, Cubit, Bloc, Provider, or Notifier — depending on the chosen state management approach. The architectural rules apply equally to all of them.

When to Use

Use this skill when:

• Designing the folder/file structure of a new Flutter app or feature.
• Creating a new View, ViewModel, Repository, or Service.
• Deciding which layer owns a piece of logic.
• Wiring dependency injection between components.
• Adding a domain (logic) layer for complex business logic.
• Refactoring an existing app from type-first to feature-first organization.
