React + Redux: "<Provider> does not support changing `store` on the fly"

Question

I'm getting this error:

<Provider> does not support changing store on the fly. It is most likely that you see this error because you updated to Redux 2.x and React Redux 2.x which no longer hot reload reducers automatically. See https://github.com/reactjs/react-redux/releases/tag/v2.0.0 for the migration instructions.

I have a component with this:

import React, { Component } from 'react';
import {
  AppRegistry,
  NativeAppEventEmitter
} from 'react-native';
import { Provider } from 'react-redux';
import { createStore } from 'redux';
import reducers from './src/reducers';
import Onboarding from "./src/onboarding/Onboarding";
import Home from "./src/home/Home";
import codePush from 'react-native-code-push';

class Edmund extends Component {

  ...

  startScreen() {
    if (this.state.screen === "HOME" ) {
      return (<Home />);
    }

    return (
      <Onboarding />
    );
  }

  render() {
    return (
      <Provider store={ createStore(reducers) }>
        { this.startScreen() }
      </Provider>
    )
  }

AppRegistry.registerComponent('Edmund', () => Edmund)

My src/reducers/index.js file:

import { combineReducers } from 'redux';

export default combineReducers({
  libraries: () => []
});

My packages:

{
  "name": "Indigo",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start"
  },
  "dependencies": {
    "lodash": "^4.13.1",
    "react": "^15.2.0",
    "react-native": "^0.27.1",
    "react-native-apple-pay": "0.0.0",
    "react-native-code-push": "^1.11.0-beta",
    "react-native-loading-spinner-overlay": "^0.3.0",
    "react-native-navigation": "^1.0.2",
    "react-native-paged-scroll-view": "^2.0.1",
    "react-native-progress": "^3.0.1",
    "react-redux": "latest",
    "redux": "^3.0.0",
    "underscore": "^1.8.3"
  },
  "devDependencies": {
    "eslint": "latest",
    "eslint-config-airbnb": "latest",
    "eslint-plugin-import": "^1.16.0",
    "eslint-plugin-jsx-a11y": "latest",
    "eslint-plugin-react": "latest"
  }
}

I'm not even doing anything fancy so I don't get why there's this error. Can anyone help?

If you dig into the react-redux code a bit you see this

if (store !== nextStore) {
  warnAboutReceivingStore()
}

So it would seem all you would have to do is move the createStore call outside.

store = createStore(reducers)


class Edmund extends Component {

  ...

  startScreen() {
    if (this.state.screen === "HOME" ) {
      return (<Home />);
    }

    return (
      <Onboarding />
    );
  }

  render() {
    return (
      <Provider store={ store }>
        { this.startScreen() }
      </Provider>
    )
  }

Haven't tested it but should work.
