useBottomTabBarHeight incorrect height?

[tamis-laan]

I'm wondering If I'm doing something wrong or if this is a bug. I have a FlatList inside a bottomTabBar navigation. I want each item in the FlatList to fill up the screen. So I calculate the width and height of a FlatList item as followed:

  import { Dimensions } from 'react-native'
  import { useBottomTabBarHeight } from '@react-navigation/bottom-tabs';

  const width  = Dimensions.get('window').width
  const height = Dimensions.get('window').height-useBottomTabBarHeight()

The function useBottomTabBarHeight() returns a value of 49.0909 however this does not produce the wanted result. By manually fudging the values I get value of 73 for the height of the bottom tab bar.

Is there something I'm missing here?

EDIT:
It looks as if the android global navigation buttons are not included inside Dimentions.get(screen).height which they should right !?

Ah for anyone dealing with the same problem it turns out it was the size of the status bar in android that was the culprit:

  import { Dimensions, StatusBar } from 'react-native'
  import { useBottomTabBarHeight } from '@react-navigation/bottom-tabs';

  const width  = Dimensions.get('window').width
  const height = Dimensions.get('window').height-useBottomTabBarHeight()-StatusBar.currentHeight

can we use some kind of conditional base here as for most of the devices useBottomTabBarHeight() works just fine but in few of them adding StatusBar.currentHeight to it works.
