Expand doesn't expand with rotated image as child

[Vera-Spoettl]

I have a document with header and footer. Everything else in between is space dedicated to the content, which is an image.

While it works perfectly fine when I don't rotate the image (the image fills the full horizontal space), it doesn't take the available space when I rotate the picture:

I have tried to move the Transform widget up in the tree, but I don't manage to get an rotated image that takes the full available height.

To Reproduce Widget build(Context context) { final head = Row(mainAxisSize: MainAxisSize.max, children: [ Expanded( child: Container( child: getHeader(context), ), ), ]);

final body = Image(MemoryImage(contentBytes!));

return Container(
  color: PdfColors.green100,
  child: Column(
    mainAxisAlignment: MainAxisAlignment.start,
    mainAxisSize: MainAxisSize.max,
    children: <Widget>[
      head,
      SizedBox(
        height: kHeaderContentPadding * PdfPageFormat.mm,
      ),
      Expanded(
        child: Align(
            alignment: Alignment.topLeft,
            child: Transform.rotateBox(
                angle: rotateContent ? pi / 2 : 0, child: body)),
      ),
      getFooter(context)
    ],
  ),
);

}

Expected behavior The rotated image should be scaled to fit into the available space.
