App.js

import React, {Component} from 'react';
import {Platform, StyleSheet, Text, View} from 'react-native';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware, compose} from 'redux';
import thunkMiddleware from 'redux-thunk';
import createLogger from 'redux-logger';
import reducer from './app/reducers';

import DashboardContainer from './app/containers/DashboardContainer';

const instructions = Platform.select({
  ios: 'Press Cmd+R to reload,\n' + 'Cmd+D or shake for dev menu!!',
  android:
    'Double tap R on your keyboard to reload,\n' +
    'Shake or press menu button for dev menu!!',
});

// middleware that logs actions
// const loggerMiddleware = createLogger({ predicate: (getState, action) => __DEV__  });

function configureStore(initialState) {
  const enhancer = compose(
    applyMiddleware(
      thunkMiddleware, // lets us dispatch() functions
    ),
  );
  return createStore(reducer, initialState, enhancer);
}

const store = configureStore({});

export default class App extends Component {
  render() {
    return (
      <Provider store={store}>
        <DashboardContainer/>
      </Provider>
    );
  }
}

Could this be changed:

export default class App extends Component {
  render() {
    return (
      <Provider store={store}>
        <DashboardContainer/>
      </Provider>
    );
  }
}

to this one?

const App = () => (
  <Provider store={store}>
     <DashboardContainer/>
  </Provider>
);

export default App;

Don't think the App needs to extend from Component as it's an entry point rather than an actual component. What do you think?

Yes its is better this way
