Draw canvas in flutter

Question

I am using drawDRRect for drawing rectangle, and want that inner color will be Colors.green and outer color Colors.blue how can I control Paint()?

 canvas.drawDRRect(
        RRect.fromRectAndCorners(
            Rect.fromLTWH(
              0,
              0,
              context.size.width,
              36,
            ),
            bottomLeft: Radius.circular(10),
            bottomRight: Radius.circular(10),
            topLeft: Radius.circular(10),
            topRight: Radius.circular(10)),
        RRect.fromRectAndCorners(
            Rect.fromLTRB(canvasStartPosition.dx, 0, canvasEndPosition.dx, 0)),
        Paint()..color = Colors.green);

you cannot do that in one `Canvas.draw*` method call – pskink Jun 26 '20 at 08:01 — pskink, Jun 26 '20 at 08:01
