/**
* The Modal component is a simple way to present content above an enclosing view.
* To render the `Modal` above other components, you'll need to wrap it with the [`Portal`](./Portal) component.
* Note that this modal is NOT accessible by default; if you need an accessible modal, please use the React Native Modal.
*
* ## Usage
* ```js
* import * as React from 'react';
* import { Modal, Portal, Text, Button, PaperProvider } from 'react-native-paper';
*
* const MyComponent = () => {
* const [visible, setVisible] = React.useState(false);
*
* const showModal = () => setVisible(true);
* const hideModal = () => setVisible(false);
* const containerStyle = {backgroundColor: 'white', padding: 20};
*
* return (
* <PaperProvider>
* <Portal>
* <Modal visible={visible} onDismiss={hideModal} contentContainerStyle={containerStyle}>
* <Text>Example Modal. Click outside this area to dismiss.</Text>
* </Modal>
* </Portal>
* <Button style={{marginTop: 30}} onPress={showModal}>
* Show
* </Button>
* </PaperProvider>
* );
* };
*
* export default MyComponent;
* ```
