It looks like you have a space in the version number '2.1 .2'. Can you remove that and then run it?

Hi @amantiwari-18, have you tried rerunning flutter clean and flutter run after making the change to the version number?

Thanks. The function that cannot be found should be coming from the path_provider plugin. Can you share the contents of the following file?

• /C:/Users/noobg/AppData/Local/Pub/Cache/hosted/pub.dev/path_provider-2.1.2/lib/path_provider.dart

from amplify-flutter.

• path_provider-2.1.2/lib/path_provider.dart

@Jordan-Nelson Thanks a lot man
the path_finder file was empty even after downloading the package multiple times

i copied the path finder code from github and pasted now it works
