Text widget as its children.
To help separate these children, a Padding widget the Text widget
is wrapped with a Padding widget.Add the following code after the ButtonSection class.
<code_start>class ButtonSection extends StatelessWidget {
const ButtonSection({super.key});
// ···
}
class ButtonWithText extends StatelessWidget {
const ButtonWithText({
super.key,
required this.color,
required this.icon,
required this.label,
