paintFront method

@override void paintFront(Canvas canvas, WheelFrameGeometry geometry)

Paints the part of the frame in front of the slices.

Implementation

@override
void paintFront(Canvas canvas, WheelFrameGeometry geometry) {
  final g = geometry;
  final double inner = _inner(g);
  final double band = g.outer - inner;
  WheelFrame.paintSliceShadow(canvas, g, strength: 0.55);

  // The dark ring the tubes are mounted on.
  canvas.drawPath(
    g.ring(inner, g.outer),
    Paint()
      ..shader = RadialGradient(
        colors: [
          Color.lerp(plateColor, Colors.white, 0.08)!,
          plateColor,
        ],
        stops: [inner / g.outer, 1.0],
      ).createShader(g.circle(g.outer)),
  );
  if (band <= 0) return;

  _paintTube(canvas, g, inner + band * 0.55, band * 0.22, color);
  _paintTube(canvas, g, inner + band * 0.12, band * 0.12, secondaryColor);
}
