How can you universally calculate the screen center for any device?

Is there a universal way to find the center of the screen, e.g. horizontally to display a button?

There is a button with options:

Button.width = 400;

Button.height = 50;

Origin = Top-left;

So when using this formula, the button is not always displayed in the center:

Button.X = PlatformInfo.CanvasDeviceWidth / 2 - Button.Width / 2

how to determine the center of the screen of any device?

Use the system viewport expressions to identify the middle of the visible area taking in to account scrolling, scale etc. You must pass a layer to take in to account the layer transform. (ViewportLeft("Layer 0") + ViewportRight("Layer 0")) / 2 will the X co-ordinate of the middle of the screen for "Layer 0", and (ViewportTop("Layer 0") + ViewportBottom("Layer 0")) / 2 the Y co-ordinate.

Thanks, you've been very helpful.
