[SebastianKurp]

🐛 Bug Report

Environment

Testing on an S8 physically and an iPhone XR via the simulator

Steps to Reproduce

Implement the video component
add an image to the posterSource prop

Expected Behavior

The Video component has a prop which allows the editing of the posterSource Styles.
Example: passing in the style of resizeMode:'cover' or width:200 so that image covers/matches the entirety of the video container

Actual Behavior

const _STYLES = StyleSheet.create({
  base: {
    overflow: 'hidden',
  },
  poster: {
    position: 'absolute',
    left: 0,
    top: 0,
    right: 0,
    bottom: 0,
    resizeMode: 'contain',
  },
  video: {
    position: 'absolute',
    left: 0,
    top: 0,
    right: 0,
    bottom: 0,
  },
});
