是否可以给出Flutter canvas.drawline的边框半径？

void paint(Canvas canvas, Size size) {
    final paint = Paint();
    paint.color = Colors.red;
    paint.strokeWidth = 10;
    canvas.drawLine(new Offset(0, 0), new Offset(size.width, size.height), paint,);
    canvas.drawLine(new Offset(size.width, 0), new Offset(0, size.height), paint,);
  }
