Problem Statement
How does Redux pattern work in Flutter?
Explanation
Redux uses a single store containing the entire app state as one immutable object. UI dispatches actions (objects describing what happened), reducers receive current state and action, and return new state without mutating the original. The store updates with new state and notifies listeners, causing UI to rebuild. This unidirectional data flow makes state changes predictable and traceable.
Flutter_redux package provides StoreProvider for providing store to the tree and StoreConnector for connecting widgets to store, mapping state to view model and rebuilding when relevant state changes. Middleware handles side effects like async operations, logging, or analytics between action dispatch and reducer execution.
Redux is powerful for complex apps requiring time-travel debugging, strict state management, or teams familiar with Redux from React. However, it involves significant boilerplate with action classes, reducers, and middleware. The single store can become large and unwieldy without proper organization. Redux is less popular in Flutter than web due to simpler alternatives like Provider, but still valuable for apps requiring Redux's strict architecture.
