flutter-architecting-apps

Layered architecture framework for scalable Flutter apps with strict separation of concerns. Design Flutter applications to scale by strictly adhering to the following principles: Separate the application into 2 to 3 distinct layers depending on complexity. Restrict communication so that a layer only interacts with the layer directly adjacent to it. Follow this sequential workflow when adding a new feature to the application. Task Progress: - Enforces three-layer structure (UI, Logic, Data) with unidirectional data flow and a single source of truth in the Data layer - UI layer contains lean Views and ViewModels that transform domain models into presentation state; Logic layer (optional) handles complex business orchestration; Data layer divides strictly into stateless Services and caching Repositories - Provides step-by-step feature implementation workflow from domain models through Services, Repositories, ViewModels, and Views, with validation via unit and widget tests - Includes complete code examples demonstrating Service wrapping, Repository caching and transformation, ViewModel state management, and reactive View binding - Core Architectural Principles - Structuring the Layers - Implementing the Data Layer - Feature Implementation Workflow - Examples - Enforce Separation of Concerns: Decouple UI rendering from business logic and data fetching.
