Working on a $2$D game trying to get the screen size from camera below is my code is it correct.

$//$ get screen size from camera $($convert viewport $0,0$ and $1,1$ to world$)$

Vector$3$ SCREEN$\_$MIN $=$ Camera.main.ViewportToWorldPoint$($new Vector$3(0,0,$ Camera.main.nearClipPlane$))$;

Vector$3$ SCREEN$\_$MAX $=$ Camera.main.ViewportToWorldPoint$($new Vector$3(1,1,$ Camera.main.nearClipPlane$))$;
