Unhandled Exception: type 'PdfReferenceHolder' is not a subtype of type 'PdfDictionary?' in type cast

Tried to run https://www.syncfusion.com/downloads/support/directtrac/general/ze/textmarkup_annotation-1766537037 with attached PDF file: X Physics EM Title Free.pmd.pdf. The sample PDF file at https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf works nice. Only the attached PDF file throwing this error.
I tried to use highlight option with attached PDF using https://support.syncfusion.com/kb/article/11033/how-to-add-text-markup-annotation-in-flutter-pdf-viewer-using-syncfusion-pdf-package and I see below error.

nice. I tried the sample you sent and it's working nice. Is there a github repo for this new sample code? I got the old code from https://www.syncfusion.com/downloads/support/directtrac/general/ze/textmarkup_annotation-1766537037
Thank you for the update. Please let us know if you need any further assistance and we will update the new sample in the KB documentation.
