[Feature/Enhancement] Request for max and min screen size

[chzhhong97]

Request to add 2 more fields for max and min screen size, so the scaling wont less or more than min and max

Idea

double get scaleWidth => screenWidth.clamp(minScreenSize?.width ?? screenWidth, maxScreenSize?.width ?? screenWidth) / _uiSize.width;
setWidth => width * scaleWidth;

Not sure is there any feature to set min and max of screen size, so I make this post to request
