Hello, I have just started using Syncfusion and I am encountering some build errors.

I have added

syncfusion_flutter_pdfviewer: ^20.4.49

to my pubspec.yaml file.

If I do a pub get and build, this works fine but as soon as I add the import statement to one of my files

import 'package:syncfusion_flutter_pdfviewer/pdfviewer.dart';

Then I encounter the following build errors:

Launching lib/main.dart on iPhone 14 Pro Max in debug mode...

Running Xcode build...

Xcode build done. 21.4s

Failed to build iOS app

Error output from Xcode build:

↳

** BUILD FAILED **

Hi Alec Haas,

The reported issue is caused by a recent upgrade to the Flutter version. In previous versions, the alignPanAxis property was a Boolean, but in version 3.7.0, it was changed to an enum type. To resolve this issue, upgrade the Flutter SDK to version 3.7.0, as all the Syncfusion Flutter packages have been updated to this version. The framework breaking change PR can be found below for your reference.

I found a solution to my problem. The problem is I had other dependencies that were messing with the syncfusion package.

syncfusion_flutter_pdf-20.4.49 depends on lints 2.0.1.

lints package was at version 1.0.1 in my project due to another package that was using it as well. I forced lints to be 2.0.1 in my pubspec.yaml file and was able to find which other packages I had to update so that my project could use lints 2.0.1.

May be a better way to compare dependencies but I did it by making a new flutter project that only depended on syncfusion_flutter_pdf-20.4.49 and seeing which packages it pulled in at what versions, then compared those to my own project.
