Can I help in some way?

+1 for this error. It is showing on Firebase, same as above.

[sarbogast]

Did anyone find a solution to this one? Because I have the same problem that randomly pops up for me and it crashes my app. I don't even know how to swallow that exception to avoid the crash.

For now, the only solution I could find was to fork the plugin and add a catch block for IllegalStateException in SyncfusionFlutterPdfViewerPlugin.java:

  @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
  boolean closeDocument(String documentID) {
    try {
      Objects.requireNonNull(documentRepo.get(documentID)).renderer.close();
      Objects.requireNonNull(documentRepo.get(documentID)).fileDescriptor.close();
      documentRepo.remove(documentID);
    } catch (IOException e) {
      e.printStackTrace();
    } catch (IllegalStateException e) {
      e.printStackTrace();
    }
    return true;
  }

[herbertamukhuma]

This is how to replicate it.

1. Assume you have two screens (HomeScreen and PdfScreen)
2. You push the pdf screen and provide it with a pdf file.
3. Next, pop back to the home page
4. If you proceed to push the PDF screen with a different pdf file, you will have the error described above

[deepika134]

We tried to replicate the reported issue with provided details, but the PDF loaded properly without any exception on our side. For your reference, we have attached the sample and included a screen recording of the output, which can be downloaded from the attachment. Please review the shared sample. If the issue still occurs on your end, kindly provide us with the modified issue replicating sample. This will be helpful for us to provide prompt solution at earliest. Sample.zip

[sarbogast]

It is obviously complicated to replicate but the android documentation for this method says that it can throw this exception that you don't catch. So why not coding defensively and actually catch that exception to prevent it from bubbling up?

We are closing this issue since we don't have enough information to reproduce it. You can reopen this anytime and share the proper issue reproducing sample and the details to proceed further.
