paint method

@override void paint(Context context)

Draw itself and its children, according to the calculated box.offset

Implementation

@override
void paint(Context context) {
  super.paint(context);

  // Make sure there are enough points to draw anything
  if (points.length < 3) {
    return;
  }

  final canvas = context.canvas;

  canvas.saveContext();

  if (fillColor != null) {
    canvas.setFillColor(fillColor!);
  }
  if (strokeColor != null) {
    canvas.setStrokeColor(strokeColor);
  }

  canvas.setLineWidth(strokeWidth);

  // Flip the points on the Y axis.
  final flippedPoints =
      points.map((e) => PdfPoint(e.x, box!.height - e.y)).toList();

  canvas.moveTo(flippedPoints[0].x, flippedPoints[0].y);
  for (var i = 0; i < flippedPoints.length; i++) {
    canvas.lineTo(flippedPoints[i].x, flippedPoints[i].y);
  }

  if (close) {
    canvas.closePath();
  }

  if (strokeColor != null && fillColor != null) {
    canvas.fillAndStrokePath();
  } else if (strokeColor != null) {
    canvas.strokePath();
  } else {
    canvas.fillPath();
  }

  canvas.restoreContext();
