layout method

@override void layout(Context context, BoxConstraints constraints, { bool parentUsesSize = false, })

First widget pass to calculate the children layout and bounding box

Implementation

@override
void layout(
  Context context,
  BoxConstraints constraints, {
  bool parentUsesSize = false,
}) {
  final w = width != null || _svgParser.width != null
      ? constraints.constrainWidth(width ?? _svgParser.width!)
      : constraints.hasBoundedWidth
      ? constraints.maxWidth
      : constraints.constrainWidth(_svgParser.viewBox.width);
  final h = height != null || _svgParser.height != null
      ? constraints.constrainHeight(height ?? _svgParser.height!)
      : constraints.hasBoundedHeight
      ? constraints.maxHeight
      : constraints.constrainHeight(_svgParser.viewBox.height);

  sizes = applyBoxFit(fit, _svgParser.viewBox.size, PdfPoint(w, h));
  box = PdfRect.fromPoints(PdfPoint.zero, sizes.destination!);
}
