just add flutter_pdfview: ^1.3.3 in your pubspec.yaml

[binSaed]

@eldarkk
Sorry for that currently I don't have time to maintain this package, as @Halipov said you could use another version of flutter_pdfview

flutter_cached_pdfview is just a wrapper for flutter_pdfview to add some features and make it easier to use

any flutter_pdfview version between >1.0.0 and <2.0.0 should work

flutter_cached_pdfview/pubspec.yaml

Line 22 in 944f872

flutter_pdfview: ">=1.0.0 <2.0.0"

just add flutter_pdfview: ^1.3.3 in your pubspec.yaml

Thank's for the workaround 👍 it fixed the crash.

@binSaed: I just cloned your repo and run the example to find out, if can fix it. But i could not reproduce it: In your example, calling PDF.cachedFromUrl() does not crash on an iPhone 16, iOS 18, Simulator while running my own app with the same implementation does. Any ideas why? Is this just a pubspec issue or what?

[FritzMatthaeus]

As I assumed, it's a pubspec.lock issue. Upgrade your dependencies to fix this issue, there is no need to add flutter_pdfview as an additional package. This is the way i fixed the issue:

1. flutter clean - clean your Flutter project
2. flutter pub upgrade - compared to flutter pub get this will upgrade all dependencies to the next minor versions. Alternatively you can delete your pubspec.lock file and run flutter pub get.
3. cd ios - go to ios Folder
4. rm Podfile.lock - delete your Podfile.lock to upgrade the plugins
5. pod install --repo-update - reinstall your plugins

Hello, @binSaed.
The problem still exists in iOS 18.1, when zoom in and zoom out , even though I updated to the latest versions of both flutter_pdfview and flutter_cached_pdfview.

From PDF().cachedFromUrl to PDF().fromUrl resolve my issue, you can also try this. Might be help 🤞.
