getClip method

@override Path getClip(Size size)

Returns a description of the clip given that the render object being clipped is of the given size.

Implementation

@override
Path getClip(Size size) {
  final path = Path();
  final centerX = size.width / 2;
  final centerY = size.height / 2;
  final radius = size.width / 2;
  final innerRadius = radius * 0.5; // Adjust inner radius for spikes
  final numSpikes = 12; // Number of spikes

  for (int i = 0; i < numSpikes; i++) {
    // Angles for outer and inner points
    final angleOuter = (i * 360 / numSpikes) * math.pi / 180;
    final angleInner = ((i + 0.5) * 360 / numSpikes) * math.pi / 180;

    // Points for outer spike tip and inner valley
    final xOuter = centerX + radius * math.cos(angleOuter);
    final yOuter = centerY + radius * math.sin(angleOuter);
    final xInner = centerX + innerRadius * math.cos(angleInner);
    final yInner = centerY + innerRadius * math.sin(angleInner);

    // Move to outer point and draw the spike
    if (i == 0) {
      path.moveTo(xOuter, yOuter); // Start the path
    } else {
      path.lineTo(xOuter, yOuter); // Line to outer spike tip
    }
    path.lineTo(xInner, yInner); // Line to inner valley
  }
  path.close(); // Close the path to complete the shape
  return path;
