@endigo i'm sorry for upset you, but could you please answered my question ?

@endigo Do you have this issue in your example ? could you please try (run) in your pc ?

@shahmirzali I did run my example project but I don't have any solution.

You could run through AndroidPdfViewer source code.

If you find a solution, please create PR because there are issues that wait for very long time.

Thanks

I have the same problem I put a textfile to jump from page and from saparese, it also disappears when I flip the phone.

this is one of the messages that I get in both cases D / jniPdfium (8057): Destroy FPDF library

I have this problem when I open a soft keyboard on another page. I'm using another page to enter user info (name, phone etc). The moment the soft keyboard is raised I get the "Destore FPDF library" message as well.

See here for others with the same issue. Their fix didn't help for me.

I moved to using a different pdf lib unfortunately. @sahmirzali . For my situation I got this one for the free community license:

syncfusion_flutter_pdfviewer: ^18.4.42-beta

syncfusion_flutter_pdfviewer doesn't have dark mode

I found that this append when the pdf is resized. Currently the package is using a vitual view, if we change to hibryd view it will fix? @endigo what do you think?

@lcyper whenever pdf disappears in debug console we can see a message:

FPDF destroyed

Possibly being printed from method channel.

If this can be catched in dart then developers can reload the pdf.

@raunak-many-ac how you reload the pdf? (changing the key of the widget)

in this file you can see an aproach to that using this function: (that package is the base for this package, but does not implement that part, and i discover that his aproach does not work well, the best is to reload the widget) onDetachedFromWindow()

@lcyper that's right.

My sense was we can do anything to reload either by reloading the widget or restarting the screen.
