Stlesswidget lifecycle.

In Flutter, StatelessWidget is a basic building block for creating user interfaces. Unlike StatefulWidget, StatelessWidget does not have a mutable state. It means that once a Stateless widget is created, its properties cannot change. Here is an overview of the lifecycle of a StatelessWidget:

1. Initialization:

• When a StatelessWidget is created, its constructor is called.?

class MyStatelessWidget extends StatelessWidget {
  final String title;

  MyStatelessWidget({required this.title});

  // Other widget code...
}        

2. Build Method:

• The build method is called when the widget is first created and whenever it needs to rebuild

@override
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: Text(title),
    ),
    body: // Widget body...
  );
}
