drawArc method

void drawArc(
  1. Rect bounds,
  2. double startAngle,
  3. double sweepAngle, {
  4. PdfPen? pen,
})

Draws an arc representing a portion of an ellipse specified by a Rect structure.

//Creates a new PDF document.
PdfDocument doc = PdfDocument()
  ..pages
      .add()
      .graphics
      //Draw Arc.
      .drawArc(Rect.fromLTWH(10, 10, 100, 200), 90, 270, pen: PdfPens.red);
//Saves the document.
List<int> bytes = doc.save();
//Dispose the document.
doc.dispose();
