Redux like store but hierarchical.

Usage #

A simple usage example:

import 'dart:async';

import 'package:storey/storey.dart';

class StringState {
  String str;

class OverwriteAction extends Action {
  const OverwriteAction(this.str);

  final String str;

StringState _handleOverwriteAction(StringState state, OverwriteAction action) {
  return state..str = action.str;

class ExchangeAction extends RequestAction<String> {
  final String str;

StringState _handleExchangeAction(StringState state, ExchangeAction action) {
  action.result = state.str;
  return state..str = action.str;

Reducer<StringState> _reducer = new MergedTypedReducer<StringState>(
      new ProxyTypedReducer<StringState, OverwriteAction>(_handleOverwriteAction),
      new ProxyTypedReducer<StringState, ExchangeAction>(_handleExchangeAction),

Store<StringState> createStore(String initialStr) {
  return new Store<StringState>(
    name: 'app',
    initialState: new StringState(initialStr),
    reducer: _reducer,
    middlewares: <Middleware>[thunkMiddleware],

Future<Null> main() async {
  Store<StringState> store = createStore('foo');
  assert(store.state.str == 'foo');

  store.dispatch(const OverwriteAction('bar'));
  assert(store.state.str == 'bar');

  ExchangeAction request = new ExchangeAction('foobar');
  assert(store.state.str == 'foobar');
  assert(request.result == 'bar');
