2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

Data Model (DTO with JSON)

import 'package:freezed_annotation/freezed_annotation.dart';
part 'user_model.freezed.dart';
part 'user_model.g.dart';

@freezed
abstract class UserModel with _$UserModel {
  const factory UserModel({
    required String id,
    required String name,
    required String email,
    @Default('') String avatarUrl,
    @JsonKey(name: 'created_at') DateTime? createdAt,
  }) = _UserModel;

  factory UserModel.fromJson(Map<String, dynamic> json) => _$UserModelFromJson(json);
}

Domain Entity (saf, JSON'siz)

@freezed
abstract class User with _$User {
  const factory User({
    required String id,
    required String name,
    required String email,
  }) = _User;
}

Union Type (sealed class alternatifi)

@freezed
sealed class AuthState with _$AuthState {
  const factory AuthState.initial() = _Initial;
  const factory AuthState.authenticated(User user) = _Authenticated;
  const factory AuthState.unauthenticated() = _Unauthenticated;
  const factory AuthState.error(String message) = _Error;
}

// Kullanim:
authState.when(
  initial: () => const SplashScreen(),
  authenticated: (user) => HomeScreen(user: user),
  unauthenticated: () => const LoginScreen(),
  error: (msg) => ErrorScreen(message: msg),
);
