flutter - Can I draw any Decoration into my canvas?

Question

I now have a class that inherits CustomPainter, and I try to draw some graphics we need in it.

What I want to know is, is there any convenient technique for us to draw a Decision object or inheritance Decision to our CustomPainter.Canvas.

In other words, we hope that it can be drawn into the canvas just by giving its size and position in the canvas.
