MORE EXAMPLES

Attention

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

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;

}
