          begin: Alignment.topCenter,
          end: Alignment.bottomCenter,
          colors: [
            accent(color).withValues(alpha: opacity),
            color.withValues(alpha: opacity),
          ],
        ).createShader(rect)
        ..isAntiAlias = true;

          colors: [
            lighten(color, 0.2).withValues(alpha: 0.6 * opacity),
            color.withValues(alpha: 0.38 * opacity),
          ],
