     * State for the bottom navigation. The state should contain the following properties:
     *
     * - `index`: a number representing the index of the active route in the `routes` array
     * - `routes`: an array containing a list of route objects used for rendering the tabs
     *
     * Each route object should contain the following properties:
     *
     * - `key`: a unique key to identify the route (required)
     * - `title`: title of the route to use as the tab label
     * - `icon`: icon to use as the tab icon, can be a string, an image source or a react component
     * - `color`: color to use as background color for shifting bottom navigation
     * - `badge`: badge to show on the tab icon, can be `true` to show a dot, `string` or `number` to show text.
     * - `accessibilityLabel`: accessibility label for the tab button
     * - `testID`: test id for the tab button
     *
     * Example:
     *
     * ```js
     * {
     *   index: 1,
     *   routes: [
     *     { key: 'music', title: 'Music', icon: 'queue-music', color: '#3F51B5' },

     *     { key: 'recents', title: 'Recents', icon: 'history', color: '#795548' },
     *     { key: 'purchased', title: 'Purchased', icon: 'shopping-cart', color: '#607D8B' },
     *   ]

     *
     * Pages are lazily rendered, which means that a page will be rendered the first time you navigate to it.
     * After initial render, all the pages stay rendered to preserve their state.
     *
     * You need to make sure that your individual routes implement a `shouldComponentUpdate` to improve the performance.
     * To make it easier to specify the components, you can use the `SceneMap` helper:
     *
     * ```js
     * renderScene = BottomNavigation.SceneMap({
     *   music: MusicRoute,
     *   albums: AlbumsRoute,
     * });
     * ```
     *
     * Specifying the components this way is easier and takes care of implementing a `shouldComponentUpdate` method.
     * Each component will receive the current route and a `jumpTo` method as it's props.
     * The `jumpTo` method can be used to navigate to other tabs programmatically:
     *
     * ```js
     * this.props.jumpTo('albums')
     * ```
