title: React Navigation Hot reload not working
body: <p>I started to refactor my entire react native navigation with <code>react-navigation</code> and now its working fine, but only thing is now app doesn't support for hot reloading. Every time I save a file that related to route. It give me an hot reload error: <code>hot.acceptCallback is not a function</code>. Please reply me, who has fixed this issue already.</p>
  
  <p>** navigation-reducer.js</p>
  
  <pre><code>import AppNavigator from '../RouteConfigs';
  
  const initialState = AppNavigator.router.getStateForAction(AppNavigator.router.getActionForPathAndParams('Startup'));
  
  export default (state = initialState, action) =&gt; {
    const nextState = AppNavigator.router.getStateForAction(action, state);
  
    return nextState || state;
  };
  </code></pre>
