Blocked by this issue as well :(

Same here, I needed to revert the whole upgrade. Let me know if there is something that I can help with.

[tim-isonsolutions]

My build is broken as well.

Can you provide at least a "ballpark" ETA so we can plan our road forward. Thanks!!

Switching to pdfx solved the issue. Thanks

[Caeruleo]

I'm using pdfx and still having this bug 😅

Having the same issue as well... Adding pdfx does not work either

[Caeruleo]

I discovered that in my case the problem was that I use a library that has as transitive dependency and old version of native_pdf_renderer (4.X.X) https://pub.dev/packages/thumbnailer.
Adding

native_pdf_renderer: ^5.0.0+1 
 pdfx: ^2.0.1+2

on dependency_overrides fixed my problem, it seems a bit risky but everything seems to work fine.
Last versions of native_pdf_renderer and pdfx seems to be able to compile fine with flutter 3, check if you've any transitive dependency that uses an older one. I searched for the old dependency on the pubspec.lock and then I used flutter pub deps to see the dependency graph.

Hope it helps anyone.

@Caeruleo FYI: https://github.com/4Q-s-r-o/thumbnailer today released new version with updated dependencies.

I am having the same issue, I have not the package in my dependencies however some package is using it and is blocking the Android app from running...

[hydev777]

The problem has been solved, the dependency thumbnailer was using an old version (version 4) of native_pdf_renderer as mentioned by @Caeruleo, so we find out we were not using that package and proceed to deleted.
