How do I enable the video in full screen

[SamarthKadam]

<YoutubePlayer
ref={playerRef}
height={190}
width={width - 21}
play={false}
webViewProps={{ containerStyle: styles.youtubeContainer, allowsFullscreenVideo: true }}
contentScale={0.5}
videoId={"nGpir4oUfJI"}
onChangeState={handleVideoStateChange}
/> When I tap the video I want the video to be played in full screen by default. How do I do it?
