StatefulWidget Explained | Flutter for Web Developers

What’s StatefulWidget?

A widget that has mutable state. State is information that can be read synchronously when the widget is built and might change during the lifetime of the widget.

Check the official documentation for more.

StatefulWidget explained for Web Developers

Stateful widgets are useful when the part of the user interface you are describing can change dynamically, e.g. due to having an internal clock-driven state, or depending on some system state. This is similar to how frameworks like React, Angular, and Vue manage component states, allowing for reactivity and dynamic updates in the UI.

Example Code

Here is an example of how to use StatefulWidget:

class YellowBird extends StatefulWidget { const YellowBird({ super.key }); @override State createState() => _YellowBirdState(); } class _YellowBirdState extends State { @override Widget build(BuildContext context) { return Container(color: const Color(0xFFFFE306)); } }

StatefulWidget Remarks

Stateful widgets can be complex but are essential for creating dynamic and interactive user interfaces in Flutter.
