SizedBox
SizedBox is a widget in Flutter that creates a box with a specified width, height, or both. It can be used to add empty spaces between widgets or control the size of widgets.
Example
SizedBox(
width: 100.0,
height: 50.0,
child: ElevatedButton(
onPressed: () {},
child: Text('Click me!'),
),
)This creates a button with a fixed width of 100.0 and a height of 50.0.
