Visual Studio Code – error: cannot find symbol when building android app in flutter using pdftron

I am trying to use the dependency https://pub.dev/packages/pdftron_flutter pdf tron to show pdf files in flutter app, when I try to build the android app, I get the error

C:UsersUSERAppDataLocalPubCachehostedpub.devpdftron_flutter-1.0.1- 32androidsrcmainjavacompdftronpdftronflutterhelpersPluginUtils.java:987: error: cannot find symbol stringRes != R.string.document_save_error_toast_message; ^ symbol: variable string location: class R

I tried to implement all the solutions in the link "error: cannot find symbol" when building for Android in flutter

Like running flutter clean and changing compileSdkVersion, minSdkVersion targetSdkVersion to 34,21,34 respectively but it did not work
