Flutter PDF Viewer Fails to load PDF with annotations.

Question

HelloI upgraded to Syncfusion_flutter_pdfviewer 26.2.13 and can't open the following pdf.  This used to work fine in version 22.1.39.  It has something to do with the terminal annotations.  I posted a link to the PDF below.  Any help would be greatly appreciated.ERROR MESSAGE: "type 'double' is not a subtype of type 'int?' in type cast" http://mmdc.nrs-corps.com/reports/reports.aspx?rID=-1483061148Garrett

Despite our efforts to resolve the issue and process the PDF with our library, the exception persists. This problem affects multiple pages in the specific document when retrieving annotations, and currently, there is no workaround to obtain the annotation count for those pages.

The fix for this issue will be included in our upcoming weekly release, scheduled for September 24, 2024.

Root cause: While loading annotations from a PDF document, we parse the annotation dictionary from the page and determine the annotation type. During this process, a specific URI annotation was embedded with an integer value stored as a double, which led to a type casting issue.
