/**
* A component to display action items in a bar. It can be placed at the top or bottom.
* The top bar usually contains the screen title, controls such as navigation buttons, menu button etc.
* The bottom bar usually provides access to a drawer and up to four actions.
*
* By default Appbar uses primary color as a background, in dark theme with `adaptive` mode it will use surface colour instead.
* See [Dark Theme](https://callstack.github.io/react-native-paper/docs/guides/theming#dark-theme) for more informations
*
* ## Usage
* ### Top bar
* ```js
* import * as React from 'react';
* import { Appbar } from 'react-native-paper';
*
* const MyComponent = () => (
* <Appbar.Header>
* <Appbar.BackAction onPress={() => {}} />
* <Appbar.Content title="Title" />
* <Appbar.Action icon="calendar" onPress={() => {}} />
* <Appbar.Action icon="magnify" onPress={() => {}} />
* </Appbar.Header>
* );
*
* export default MyComponent;
* ```
*
* ### Bottom bar
* ```js
* import * as React from 'react';
* import { StyleSheet } from 'react-native';
* import { Appbar, FAB, useTheme } from 'react-native-paper';
* import { useSafeAreaInsets } from 'react-native-safe-area-context';
*
* const BOTTOM_APPBAR_HEIGHT = 80;
* const MEDIUM_FAB_HEIGHT = 56;
*
* const MyComponent = () => {
* const { bottom } = useSafeAreaInsets();
* const theme = useTheme();
*
* return (
* <Appbar
* style={[
* styles.bottom,
* {
* height: BOTTOM_APPBAR_HEIGHT + bottom,
* backgroundColor: theme.colors.elevation.level2,
* },
* ]}
* safeAreaInsets={{ bottom }}
* >
* <Appbar.Action icon="archive" onPress={() => {}} />
* <Appbar.Action icon="email" onPress={() => {}} />
* <Appbar.Action icon="label" onPress={() => {}} />
* <Appbar.Action icon="delete" onPress={() => {}} />
* <FAB
* mode="flat"
* size="medium"
* icon="plus"
* onPress={() => {}}
* style={[
* styles.fab,
* { top: (BOTTOM_APPBAR_HEIGHT - MEDIUM_FAB_HEIGHT) / 2 },
* ]}
* />
* </Appbar>
* );
* };
*
* const styles = StyleSheet.create({
* bottom: {
* backgroundColor: 'aquamarine',
* position: 'absolute',
* left: 0,
* right: 0,
* bottom: 0,
* },
* fab: {
* position: 'absolute',
* right: 16,
* },
* });
*
* export default MyComponent;
* ```
