/**
 * Toggle buttons can be used to group related options. To emphasize groups of related toggle buttons,
 * a group should share a common container.

 * <div class="screenshots">
 *   <img class="medium" src="screenshots/toggle-button.png" />
 * </div>
 *
 * ## Usage
 * ```js
 * import * as React from 'react';
 * import { ToggleButton } from 'react-native-paper';
 *
 * const ToggleButtonExample = () => {
 *   const [status, setStatus] = React.useState('checked');
 *
 *   const onButtonToggle = value => {
 *     setStatus(status === 'checked' ? 'unchecked' : 'checked');
 *   };
 *
 *   return (
 *     <ToggleButton
 *       icon="bluetooth"
 *       value="bluetooth"
 *       status={status}
 *       onPress={onButtonToggle}
 *     />
 *   );
 * };
 *
 * export default ToggleButtonExample;
 *
 * ```
