Implementation

@override
paint(Canvas canvas, Paint? paint, Size size) {
  const circleSpacing = 4;
  final width = size.width;
  final height = size.height;
  for (int i = 0; i < 3; i++) {
    paint!.color = paint.color.withAlpha(alphaInts[i]);
    canvas.drawCircle(Offset(width / 2, height / 2),
        (width / 2 - circleSpacing) * scaleDoubles[i], paint);
  }
}
