TypeError: Cannot perform Construct on a detached ArrayBuffer #97

When I open the PDF document, go back and then return again with forward arrow to the previously opened document, I receive an error:

TypeError: Cannot perform Construct on a detached ArrayBuffer

Any ideas?

Please show your code that calls pdfrx.

Unfortunately, I can't. It is a private code. I retrieve the PDFs via PdfViewer and PdfDocumentRefData, Also, what I have noticed, seems that my Layout is faster then my controller - e.g I can't retrieve at the beginning the number of pages, I need to check first if(controller.isReady ? ) then I can get my data - or to make some interaction with the page(scroll, next page etc.), then the controller is ready. Not sure what can cause these problems

I'm not interested in your actual code. Without you providing any kind of code fragments or something that reproduces the issue, I can't do anything.

espresso3389 commented 2 months ago

Is it really OK for you? If you create some repro code (completely new code that reproduces the same issue), it's very helpful to understand your situation.

The problem was when I want to open the document, so I am checking the type of the file. Needed to pack my raw data inside of Uint8List.fromList(rawData). It is done. Tnx anyway
