Hey there -- took a look at your code. The problem is that you're creating the Store<AppState>
inside the build
function of a StatelessWidget (MusicParty
). As a heads up: build
functions are called over and over again. In this case, Hot Reload will trigger the build
function in your MusicParty
after hot reload.
This means you're creating a new store each time the build method is called, and that's why you're running into trouble.
Instead, you need to create the Store exactly once: Either in the main
function or in a StatefulWidget
at the top of your Widget hierarchy.
Please try this as an alternative and everything should be working:
import 'package:firebaseredux/models/app_state.dart';
import 'package:firebaseredux/pages/home_page.dart';
import 'package:firebaseredux/reducers/app_reducer.dart';
import 'package:flutter/material.dart';
import 'package:flutter_redux/flutter_redux.dart';
import 'package:redux/redux.dart';
import 'package:redux_logging/redux_logging.dart';
void main() => runApp(new MusicParty());
class MusicParty extends StatefulWidget {
@override
MusicPartyState createState() {
return new MusicPartyState();
}
}
class MusicPartyState extends State<MusicParty> {
final store = Store<AppState>(
appReducer,
initialState: new AppState(count: 0, isLoading: false),
middleware: [LoggingMiddleware.printer()],
);
@override
Widget build(BuildContext context) {
final title = "Me Suite";
return new StoreProvider<AppState>(
store: store,
child: MaterialApp(
title: title,
home: HomePage(title),
),
);
}
}

Thank you. Now everything works as expected.

This will still fail with persist, load the store asnyc as the app loads with the following.
void main() async {
runApp(MyApp(store: await AppState.createStore()));
}

Thank you, you saved my life!!
