How to modify the padding in SafeAreaView?

I am trying to position element in the left-upper corner of the screen (there is some margin around). Because of the notch on the iPhone X I am using SafeAreaView. Unfortunately the SafeAreaView padding is enormous, it goes way out of the status bar / notch area. Because of that the element which should visually be in the corner it's now much lower than on other devices.

I looked into StatusBar.currentHeight, but that is supported only for Android. Another option was to use https://github.com/react-native-community/react-native-safe-area-view which has a forceInset parameter. Unfortunately, setting it as { top: xx } makes it work like a normal View with a top padding for all devices (the ones without notch as well).

How can I have a SafeAreaView but with a modified top padding?

Yet another approach to deal with padding for SafeAreaView tag before react-native API is changed:

you need to add another view inside the SafeAreaView and apply your padding there, because SafeAreaView uses its own padding style prop to implement its behavior, overriding the one you pass to it.

I had a similar problem months ago, so I wrote an util to give me the correct height of top/bottom SafeArea to add as padding to a normal react-native View, and then play with them by adding/removing more padding. Here is the code:

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

export function isIphoneX () {
  const iphoneXLength = 812
  const iphoneXSMaxLength = 896
  const windowDimensions = Dimensions.get('window')
  return (
    Platform.OS === 'ios' &&
    !Platform.isPad &&
    !Platform.isTVOS &&
    (windowDimensions.width === iphoneXLength ||
      windowDimensions.height === iphoneXLength ||
      windowDimensions.width === iphoneXSMaxLength ||
      windowDimensions.height === iphoneXSMaxLength)
  )
}

const DimensionsStyle = {
  safeAreaTopHeight: Platform.OS === 'ios' ? (isIphoneX() ? 44 : 20) : 0,
  safeAreaBottomHeight: Platform.OS === 'ios' && isIphoneX() ? 35 : 0,
  tabBarHeight: Platform.OS === 'ios' ? 17 : 20,
  bottomAreaHeight: Platform.OS === 'ios' && isIphoneX() ? 34 : 0
}

export default DimensionsStyle

This code works because we know that iPhone X and iPhone XS have a 812p height, and iPhone XSMax and XR have 896p height.

Then you can simply import this util into your view and use it like this:

import Dimension from '../../../utils/DimensionUtils' // path of the util
//
// rest of the code
//
const styles = StyleSheet.create({
  container: {
    paddingTop: Dimension.safeAreaTopHeight // here you can edit the height of the safeare :))
  }
})
