rx reactor
Features #
Simple MVVM reactive programming tool using ReactiveX for flutter.
It helps to completely separate business logic from view.
The fundamental idea comes from ReactorKit [https://github.com/ReactorKit/ReactorKit].

Usage #
Reactor
/// declare actions
enum _Action {
setTabItem,
}
/// declare mutations
enum _Mutation {
setTabItem,
}
/// state
class MainScreenState {
final selectedTabIndex = BehaviorSubject.seeded(0);
}
/// inherits from ContextReactor
class MainScreenReactor extends ContextReactor<MainState> {
@override
final state = MainState();
setTabItem(int index) =>
action.add(ReactAction(id: _Action.setTabItem, data: index));
@override
Stream<ReactMutation> mutate(ReactAction action) {
switch (action.id as _Action) {
case _Action.setTabItem:
return Stream<ReactMutation>.value(
ReactMutation(id: _Mutation.setTabItem, data: action.data));
}
}
@override
void reduce(ReactMutation mutation, MainState state) async {
switch (mutation.id as _Mutation) {
case _Mutation.setTabItem:
state.selectedTabIndex.add(mutation.data);
break;
}
}
