/**
* Surface is a basic container that can give depth to an element with elevation shadow.
* On dark theme with `adaptive` mode, surface is constructed by also placing a semi-transparent white overlay over a component surface.
* See [Dark Theme](https://callstack.github.io/react-native-paper/docs/guides/theming#dark-theme) for more information.
* Overlay and shadow can be applied by specifying the `elevation` property both on Android and iOS.
*
* ## Usage
* ```js
* import * as React from 'react';
* import { Surface, Text } from 'react-native-paper';
* import { StyleSheet } from 'react-native';
*
* const MyComponent = () => (
* <Surface style={styles.surface} elevation={4}>
* <Text>Surface</Text>
* </Surface>
* );
*
* export default MyComponent;
*
* const styles = StyleSheet.create({
* surface: {
* padding: 8,
* height: 80,
* width: 80,
* alignItems: 'center',
* justifyContent: 'center',
* },
* });
* ```
