Widget explained for Android Developers

For Android developers familiar with Kotlin, the Widget class can be compared to Android Views. Just as Views are the UI components in Android, Widgets serve a similar purpose in Flutter. However, unlike Android Views, which can have mutable states, Flutter Widgets are immutable. To manage state, Flutter uses StatefulWidgets, akin to Android’s ViewModels.

Example Code

Here is an example of how to use Widget:

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      color: Colors.blue,
      child: Text('Hello, Flutter!'),
    );
  }
}

Widget Remarks

Understanding the Widget class is crucial for building Flutter applications. Its immutability and structure provide a robust way to create dynamic UIs.
