2
3import { Dimensions } from 'react-native';
4then you have to get the dimensions of the window
5
6const win = Dimensions.get('window');
7Now calculate ratio as
8
9const ratio = win.width/541; //541 is actual image width
10now the add style to your image as
11
12imageStyle: {
13    width: win.width,
14    height: 362 * ratio, //362 is actual height of image
15}
