SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Design patterns for building robust, immutable application state in AsyncRedux, enabling safe, predictable updates without mutating original state.

Core Features & Use Cases

  • Static initialState() factories to provide default state trees.
  • copy() methods to create modified state instances with preserved immutability.
  • Nested/composite state design to compose multiple state objects (e.g., AppState, User, Settings) with consistent patterns.
  • Optional integration with fast_immutable_collections to manage IList, ISet, and IMap when needed.

Quick Start

Create AppState with nested components and use copy() to produce updated immutable states.

FAQPage Schema
How do I design immutable state models for AsyncRedux in Flutter?

To design immutable AsyncRedux state models, define Dart classes with static initialState() factories for default state trees and copy() methods to create modified instances, ensuring safe, predictable updates without mutating the original state.

What is the best way to structure nested state compositions in Dart Redux?

Structuring nested Redux state in Dart involves composing multiple immutable state objects like AppState, User, and Settings. You apply consistent copy-on-write patterns across these nested objects to maintain predictable state transitions.

Can I use fast_immutable_collections with AsyncRedux state classes?

Yes, you can integrate fast_immutable_collections with AsyncRedux state classes. This optional integration allows you to manage IList, IMap, and ISet within your immutable state tree for efficient collection handling.

How do I provide a default state tree for an AsyncRedux application?

You provide a default AsyncRedux state tree by implementing static initialState() factories in your state classes. These factories instantiate the initial default values for your AppState and nested components.

Why should I use copy() methods instead of directly mutating state properties?

Using copy() methods instead of direct mutation enforces copy-on-write immutability, which prevents unintended side effects. This pattern creates new state instances with modified fields while preserving the original state object intact.

Does AsyncRedux state design include guidance for integrating reducers and testing?

Yes, AsyncRedux state design conforming to best practices includes guidance for integrating actions, reducers, and testing. This ensures your immutable state models work correctly within the broader Redux architecture and testing setup.
