# Attention
To use a template as an item type, you need to implement **toString**, **equals** and **hashcode**, as shown below:

```dart
class UserModel {
  final String id;
  final DateTime createdAt;
  final String name;
  final String avatar;

UserModel({this.id, this.createdAt, this.name, this.avatar});

@override
  String toString() => name;

@override
  operator ==(o) => o is UserModel && o.id == id;

@override
  int get hashCode => id.hashCode^name.hashCode^createdAt.hashCode;

}
```

## Getting Started

a library module containing code that can be shared easily across
multiple Flutter or Dart projects.
