Thankyou!!1 i have another problem though in catalog.dart
---code---

factory Item.fromMap(Map<String, dynamic> map) {
if (map == null) return null;

return Item(
  id: map['id'],
  name: map['name'],
  desc: map['desc'],
  price: map['price'],
  color: map['color'],
  image: map['image'],
);

}

--------A value of type 'Null' can't be returned from the constructor 'Item.fromMap' because it has a return type of 'Item'.
