How can I make background color fill all screen except a portion of it (To be transparent)?

You can make a canvas, draw a rect full screen then draw the center rect with `BlendMode.Clear`. To make it work you have to set `.graphicsLayer(alpha = 0.99f)` otherwise the center rect will be black instead of transparent.

Excuse the little bit messy code :wink:

Alternatively you could draw four rects surrounding your inner empty space :shrug:

Thanks <@U03JJ9GFVKQ> but did you know How can I put the rect at the center of canvas?
