StatelessWidget Explained | Flutter for Android Developers

What’s StatelessWidget?

A widget that does not require mutable state. A stateless widget is a widget that describes part of the user interface by building a constellation of other widgets that describe the user interface more concretely.

StatelessWidget explained for Android Developers

Stateless widgets are useful when the part of the user interface you are describing does not depend on anything other than the configuration information in the object itself and the BuildContext in which the widget is inflated. This is similar to using a View in Android that does not change its state, relying solely on the data passed to it, akin to how a Fragment might be used in a static manner in Android/Kotlin.

Example Code

Here is an example of how to use StatelessWidget:

class GreenFrog extends StatelessWidget {
  const GreenFrog({super.key});
  @override
  Widget build(BuildContext context) {
    return Container(color: const Color(0xFF2DBD3A));
  }
}
