Launching lib\main.dart on sdk gphone64 x86 64 in debug mode...

its saying that duplicate classes are being found but i dont know how can i remove them any help would be highly appreciated, i even tried solving conflicts but nothing worked ?

  • it seems like that `awesome_notifications ` conflicted with `awesome_notifications_fcm `, try to remove one and rebuild – Zhentao Jul 18 '23 at 08:05
  • well see here https://pub.dev/packages/awesome_notifications_fcm#plugin-dependencies they have mentioned to use both of the libs together in order to make it work, awesome_notifications_fcm is built on top of awesome_notifications – Akash Kashyap Jul 18 '23 at 08:17
  • Bro try to check grandle dependancies. you may added duplicate dependency for it – Vinesh Chauhan Jul 21 '23 at 12:04
  • @AkashKashyap Hey bro, im getting the same error now. did you fix it? – Ozan Aug 18 '23 at 13:48
