How to fix gradle error in flutter project-CodePudding

I am getting this gradle error when running flutter project:

I am using code from github for flutter pdf view and also using firebase for it.

Launching lib\main.dart on AOSP on IA Emulator in debug mode...

 - 'GUID' is from 'package:win32/src/structs.dart' ('/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/win32-1.7.4 1/lib/src/structs.dart').

          knownFolderID.addressOf, KF_FLAG_DEFAULT, NULL, pathPtrPtr);
