Couldn’t find headerLabel to use it. Tried to use variable headerLabel but could not find solution

class ProfileHeaderLabel extends StatelessWidget {
  final String headerLabel;
  const ProfileHeaderLabel({
   Key? key, required this.headerLabel
  }): super(key: key)

  @override
  Widget build(BuildContext context) {
    return SizedBox(
      height: 40,
      child: Row(
        mainAxisAlignment: MainAxisAlignment.center,
        children: const [
          SizedBox(
            height: 40,
            width: 50,
            child: Divider(
              color: Colors.grey,
              thickness: 1,
            ),
          ),
          // 'Account info'
          Text(
            headerLabel,
            style: TextStyle(
                color: Colors.grey, fontSize: 24, fontWeight: FontWeight.w600),
          ),
