  // Wrap [StickerWidget]s in [CrawlStickerSurface]
  // and change [StickerWidget.show] to crawl sticker on that surface like a worm.
  return CrawlStickerSurface(
    sticksCount: sticksCount,
    // Size available only when stick is building for crawling.
    stickBuilder: (context, StickType type, Size? size) {
      return Container(
        width: size?.width,
        height: size?.height,
        decoration: stickDecoration,
