Sparkle util (set foreground=true untuk bintang terang di depan).

Implementation

static void drawSparkles({
  required Canvas canvas,
  required Offset center,
  required double progress,
  required Color baseColor,
  required math.Random random,
  required double maxDistance,
  required int sparkleCount,
  required bool foreground,
}) {
  for (int i = 0; i < sparkleCount; i++) {
    final d = random.nextDouble() * maxDistance * (foreground ? 1.5 : 1.2);
    final a = random.nextDouble() * math.pi * 2;
    final pos =
        Offset(center.dx + math.cos(a) * d, center.dy + math.sin(a) * d);

    final size =
        random.nextDouble() * (foreground ? 4 : 3) + (foreground ? 2 : 1);

    final col = HSLColor.fromColor(baseColor)
        .withLightness(0.7 + random.nextDouble() * .3)
        .withSaturation(0.7 + random.nextDouble() * .3)
        .toColor()
        .withOpacity(foreground
            ? (.5 + random.nextDouble() * .5)
            : (.3 + random.nextDouble() * .4));

    foreground
        ? drawStar(canvas, pos, size, col)
        : canvas.drawCircle(pos, size, Paint()..color = col);
  }
