flutter_ddd

Notes app sample in Dart / Flutter with DDD.

This is an outcome of my attempt to understand Domain-Driven Design and consider how I can introduce it to app development in Flutter. The attempt began when I wondered what directory structure would be better and started to try to figure it out.

DDD may be too much for a small app like this, resulting in unnecessarily bloated code, but should help you more in development of larger apps.

Branches

• master (current branch)
  • The original example with ChangeNotifier
• state_notifier
  • A newer example with StateNotifier (w/o Freezed)
    • I tried this to see if it could make things easier, but unfortunately I did not really see benefits from just separating states from notifiers and making the states immutable in this project. It may matter more in other projects.
