The attempt began when I wondered what directory structure would be 9 | better and started to try to figure it out. 10 | 11 | DDD may be too much for a small app like this, resulting in unnecessarily bloated code, but should 12 | help you more in development of larger apps. 13 | 14 | ## Branches 15 | 16 | * master (current branch) 17 | * The original example with ChangeNotifier 18 | * [state_notifier](https://github.com/kaboc/flutter_ddd/tree/state_notifier) 19 | * A newer example with StateNotifier (w/o Freezed) 20 | * I tried this to see if it could make things easier, but unfortunately I did not really see 21 | benefits from just separating states from notifiers and making the states immutable in this 22 | project. It may matter more in other projects. 23 | 24 | ## Related articles 25 | 26 | - [Dart/Flutterでドメイン駆動設計（DDD）してみた - 導入編](https://kabochapo.hateblo.jp/entry/2019/11/01/195130) (Japanese) 27 | - This post describes what DDD and architectures are like and what structure I chose. 28 | -
