Key Concepts

Base Entity

All domain entities extend from BaseEntity:

class User extends BaseEntity {
  final String name;
  final String email;

  User({
    required super.id,
    required this.name,
    required this.email,
  });
}

Result Type

Handle errors functionally with the Result type:

Future<Result<User, Failure>> getUser(String id) async {
  try {
    final user = await api.fetchUser(id);
    return Success(user);
  } catch (e) {
    return Failure(NetworkFailure(e.toString()));
  }
}
