SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Flutter projects often suffer from architectural drift as they scale, leading to tangled UI, business logic, and data handling. This Skill advocates a layered approach to keep UI, logic, and data concerns cleanly separated, aiding maintainability and scalability.

Core Features & Use Cases

Enforces Separation of Concerns by organizing code into UI, Logic, and Data layers.
Maintains a Single Source of Truth (SSOT) by centralizing state in the Data layer and controlling mutations.
Enables Unidirectional Data Flow (UDF) from the Data/Logic layers to the UI.
Supports refactoring and new projects by providing a clear blueprint for structuring services, repositories, and view models.

Quick Start

Outline a minimal Flutter feature using a UI-Logic-Data stack and implement a small repository-example demonstrating the layered architecture.

FAQPage Schema

How do I structure a Flutter app with layered architecture?▼

Separate concerns by organizing code into UI, Logic, and Data layers to ensure scalability and testability. This approach enforces separation of concerns, maintaining a single source of truth and unidirectional data flow from data to UI.

What is the best way to manage state in Flutter using a single source of truth?▼

Centralize state in the Data layer and control mutations to maintain a single source of truth. This enables unidirectional data flow, ensuring the UI reflects data changes predictably without tangled business logic.

How do I refactor a Flutter project to separate UI, logic, and data?▼

Refactor by restructuring code into UI, Logic, and Data layers using a clear blueprint for services, repositories, and view models. This minimizes coupling between layers and restores maintainability in scaling apps.

Can I use this layered architecture for new Flutter projects and refactoring?▼

Yes, this architecture applies to both new projects and refactoring efforts. It provides a clear blueprint for structuring services and repositories while satisfying requirements for minimal coupling and unidirectional data flow.

Why does my Flutter app need one service per external data source?▼

Using one service per external data source minimizes coupling and maintains a single source of truth. This architectural constraint ensures data interactions remain isolated, testable, and cleanly separated from business logic.

When should I not use a layered architecture in Flutter?▼

Avoid layered architecture for trivial Flutter apps where the overhead of separating UI, Logic, and Data outweighs maintainability benefits. It is essential primarily for scaling apps requiring strict separation of concerns and testability.
