Details

1. The application bootstraps in App.js and hands over the navigation to the src/containers/Router.js component.
2. This Router.js container helps manage the navigation between various screens in the application and also provides the Header and the Navbar Switch to switch between story types (Top, Show, Ask, Best, Job, New). It does so using the excellent react-native-router-flux package.
   • The navbar switch to switch between story types is setup inside the src/containers/StoryList.js component bootstrapped in the changeStoryType function as we only require it on the main story listing screen.
3. The screen that loads by default is the src/containers/StoryList.js component and it loads all stories of a certain type ('Top') by default.
4. A click on a certain story triggers the src/containers/SingleStoryItem.js component which loads the comments of a certain story and shows more details about it.
