Managing State in Flutter Contents Core Concepts Architecture and Data Flow Workflow: Selecting a State Management Approach Workflow: Implementing MVVM with Provider Examples Core Concepts Flutter's UI is declarative; it is built to reflect the current state of the app ( UI = f(state) ). When state changes, trigger a rebuild of the UI that depends on that state. Distinguish between two primary types of state to determine your management strategy: Ephemeral State (Local State): State contained neatly within a single widget (e.g., current page in a PageView , current selected tab, animation progress). Manage this using a StatefulWidget and setState() . App State (Shared State): State shared across multiple parts of the app and maintained between user sessions (e.g., user preferences, login info, shopping cart contents). Manage this using advanced approaches like InheritedWidget , the provider package, and the MVVM architecture. Architecture and Data Flow Implement the Model-View-ViewModel (MVVM) design pattern combined with Unidirectional Data Flow (UDF) for scalable app state management.
