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 center = Offset(size.width / 2, size.height / 2);

  // 创建临时布局来计算顶点
  final layout = orientation == HexOrientation.pointy
      ? HexLayout.pointy(size: hexSize, origin: center)
      : HexLayout.flat(size: hexSize, origin: center);

  // 获取六边形的顶点（中心坐标为 0,0,0）
  final corners = layout.hexCorners(const HexCoordinate(0, 0, 0));

  if (corners.isNotEmpty) {
    path.moveTo(corners[0].dx, corners[0].dy);
    for (var i = 1; i < corners.length; i++) {
      path.lineTo(corners[i].dx, corners[i].dy);
    }
    path.close();
  }

  return path;
