Understanding State Management in Flutter (Part 2)

In Flutter development, efficient and reusable code is crucial, and two tools, InheritedWidget and the Provider package, facilitate state management and code reuse within the widget tree. InheritedWidget allows multiple widgets to access shared data without excessive boilerplate by passing data down the widget tree using the context.dependOnInheritedWidgetOfExactType<>() method. An example is given through a counter app that utilizes InheritedWidget for state management. On the other hand, the Provider package simplifies state sharing across the widget tree with less boilerplate and performance benefits, using a ChangeNotifier to update and notify widgets of state changes. An app example demonstrates Provider's efficiency by incrementing a number when clicked, with automatic widget rebuilding when state changes occur. The article highlights how these two approaches streamline state management in Flutter, encouraging developers to explore their capabilities for enhanced application development.
