    You are missing a ; after your constructor :

    class CategoryTile extends StatelessWidget {
  final image, categoryName;
  CategoryTile({super.key, this.categoryName, this.image});


  // ignore: empty_constructor_bodies
  @override
  Widget build(BuildContext context) {
    return Container(
      child: Stack( children: [
        Image.asset(image,
        width: 120,
        height: 60,
        )
      ],),
    );
  }
}

    When you define a constructor, you need to provide a function body for it.

    Here is the updated code:

    class CategoryTile extends StatelessWidget {
  final String image;
  final String categoryName;

  CategoryTile({
    Key? key,
    required this.categoryName,
    required this.image,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Container(
      child: Stack(
        children: [
          Image.asset(
            image,
            width: 120,
            height: 60,
          )
        ],
      ),
    );
  }
}
