Looking for get statusBarHeight?

I have found code that is I think the best way to get height in android and ios.


import { Dimensions, Platform, StatusBar } from 'react-native';

const X_WIDTH = 375;
const X_HEIGHT = 812;

const XSMAX_WIDTH = 414;
const XSMAX_HEIGHT = 896;

const { height, width } = Dimensions.get('window');

export const isIPhoneX = () => Platform.OS === 'ios' && !Platform.isPad && !Platform.isTVOS
    ? width === X_WIDTH && height === X_HEIGHT || width === XSMAX_WIDTH && height === XSMAX_HEIGHT
    : false;

export const StatusBarHeight = Platform.select({
    ios: isIPhoneX() ? 44 : 20,
    android: StatusBar.currentHeight,
    default: 0

Then use it directly when imported:

import { StatusBarHeight } from './StatusBarHeight.js'

height: StatusBarHeight
