@override void onPaint(Canvas canvas)

Draws segment in series bounds.

Implementation

@override
void onPaint(Canvas canvas) {
  if (segmentRect == null) {
    return;
  }
  final Rect? paintRect =
      Rect.lerp(_oldSegmentRect, segmentRect, animationFactor);
  if (paintRect == null || paintRect.isEmpty) {
    return;
  }

  Paint paint = getFillPaint();
  if (paint.color != Colors.transparent) {
    canvas.drawOval(paintRect, paint);
  }

  paint = getStrokePaint();
  final double strokeWidth = paint.strokeWidth;
  if (paint.color != Colors.transparent && strokeWidth > 0) {
    final Path strokePath = Path()
      ..addOval(paintRect.deflate(strokeWidth / 2));
    drawDashes(canvas, series.dashArray, paint, path: strokePath);
  }
}
