I am facing the same exact issue with version 20.4.48 (latest currently). Is this plugin version working for anyone?

GSORF commented 1 year ago

I can confirm this issue with the latest version.

I tried switching between iOS and Android and clearing my pub cache via: dart pub cache clean

Nothing helped. The error log is quite long, maybe it helps when I post the full error:

I am on a M1 MacBook Pro 2020 with MacOS Ventura 13.0.1.

A fix would be highly appreciated!

FYI: Duplicate of #1067 and #1064 .

Solution proposed in #1064 is to upgrade the flutter SDK by running flutter upgrade

This worked for me and I am able to now compile my iOS app with the syncfusion SfPDFViewer widget! But before this, I broke my flutter installation and it took me an hour to google for the fixes, so beware of that!

I do not remember all of the commands, but among these are the following:

Make sure you are on the "stable" channel by running flutter channel stable
Check your paths on MacOS for double slashes at the beginning of your dart and flutter executables by running echo $PATH . Otherwise you will get an error message about "Cannot extract a non-Windows file path from a file URI with an authority".
Update your flutter pub dependencies using flutter pub outdated and flutter pub upgrade and then upgrading flutter again using flutter channel stable and flutter upgrade. Otherwise you get an error message like "The method 'File.create' doesn't have the named parameter 'exclusive' of overridden method".
Update your cocoa pods installation to the latest version using a combination of flutter clean, rm -Rf ios/Pods, rm -Rf ios/.symlinks, rm -Rf ios/Flutter/Flutter.framework, rm -Rf ios/Flutter/Flutter.podspec, flutter pub get, cd ios, arch -x86_64 pod install (specifically M1 MacOS!), flutter build ios and flutter run. Otherwise you get the error message "error running pod install".

It was quite chaotic and in retrospective I think it would have been easier to just re-install flutter. However, I did not test that.

I hope that this will help you resolving your issues regarding the most recent release of the SF flutter widget.

Kind regards, Adam

Upgrading flutter is way too much hassle. I don't want to break existing dependencies and open another can of worms. Would either go for a different library or use a version of this one which is compatiable with my flutter version ( [✓] Flutter (Channel beta, 3.7.0-1.3.pre, on macOS 12.5 21G72 darwin-x64, locale en-GB) )

Currently trying to find which version will work for my flutter.

engineer-ece commented 1 year ago

syncfusion_flutter_core: 20.3.59 syncfusion_flutter_pdf: 20.3.59 syncfusion_flutter_pdfviewer: 20.3.59

This is working, thank you sir, i checked. In new version only throwing bug in above

irfanajaffer commented 1 year ago

We found that the problem is due to the older version of the xml package being referred to in your project. Recently, the XmlBuilder attribute value API has been updated from non-nullable to nullable type; you can refer to the following API reference for further details.

Xml package version 6.2.0 | Xml package version 6.2.2 -- | -- https://pub.dev/documentation/xml/6.2.0/xml/XmlBuilder/attribute.html | https://pub.dev/documentation/xml/latest/xml/XmlBuilder/attribute.html

So, we request you to update your pub cache by using the following command to resolve the issue.

dart pub cache add xml --version "6.2.2"

You can refer https://dart.dev/tools/pub/cmd/pub-cache for more details.
