/**
* Portal host renders all of its children `Portal` elements.
* For example, you can wrap a screen in `Portal.Host` to render items above the screen.
* If you're using the `Provider` component, it already includes `Portal.Host`.
*
* ## Usage
* ```js
* import * as React from 'react';
* import { Text } from 'react-native';
* import { Portal } from 'react-native-paper';
*
* const MyComponent = () => (
* <Portal.Host>
* <Text>Content of the app</Text>
* </Portal.Host>
* );
*
* export default MyComponent;
* ```
*
* Here any `Portal` elements under `<App />` are rendered alongside `<App />` and will appear above `<App />` like a `Modal`.
