Minimalist Todo Planner app built around the idea of efficiency and clean aesthetic.
Deer uses BLoC (Business Logic Component) pattern to manage app state. If you want to use Streams in your Flutter project, then I think this is the way to go. BLoC plays exceptionally well with Flutter's reactive nature, especially since Flutter has built-in
Each screen is splitted into 4 files:
- screen (UI itself)
Instead of calling
setState() in screen file, an action is pushed to bloc's input
Stream<Action>. Then, bloc resolves that action and updates the output
Stream<State>. Every state update is listened to inside screen with
StreamBuilder, which updates the UI when needed. This way we achieve clear separation of concerns.
Usually with BLoC,
Sink is used for input Stream, and
BehaviorSubject for output Stream.
