layout method

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

First widget pass to calculate the children layout and bounding box

Implementation

@override
void layout(Context context, BoxConstraints constraints,
    {bool parentUsesSize = false}) {
  box = PdfRect.fromPoints(PdfPoint.zero, _computeSize(constraints));
  _context = context.inheritFrom(this);
  _child = _build(_context!);
  _child.layout(_context!, BoxConstraints.tight(box!.size));
}
