What is Flutter State Management?

In Flutter, state management is the process of controlling how an app’s data (or state) changes and updates the user interface (UI). Effective state management ensures that an app behaves responsively and efficiently when the underlying data changes. Since Flutter applications are built using widgets, each widget can have its own state, and managing this efficiently becomes crucial, especially as apps grow in complexity.

Core Concepts in Flutter State Management

1. State

In Flutter, state is the data that influences a widget’s behavior or appearance. For instance, in a counter app, the number displayed on the screen represents the app’s state.

2. Stateless vs Stateful Widgets:

• Stateless Widgets: These widgets are static and don’t update once built. They are used for displaying static content, such as text or icons.
• Stateful Widgets: These can change their state during runtime, like a button that increments a counter when clicked.
