How do you draw a rounded rectangle on a Canvas in .NET MAUI?

Rounded rectangles and squares can be drawn on an ICanvas using the DrawRoundedRectangle method, which requires x, y, width, height, and cornerRadius arguments, of type float. The cornerRadius argument specifies the radius used to round the corners of the rectangle.
The following example shows how to draw a rounded rectangle:

C#

canvas.StrokeColor = Colors.Green;
canvas.StrokeSize = 4;
canvas.DrawRoundedRectangle(10, 10, 100, 50, 12);
