@amantiwari-18 can you provide the output of 'flutter pub deps --no-dev --style=compact' and the code you are using the configure amplify?

@amantiwari-18 can you provide the output of 'flutter pub deps --no-dev --style=compact' and the code you are using the configure amplify?

Error on line 42, column 18 of pubspec.yaml: Invalid version constraint: Expected version number after "^" in "^2.1 .2", got "2.1 .2". ╷ 42 │ path_provider: ^2.1 .2 │ ^^^^^^^

it says this when i write flutter pub deps --no-dev --style=compact

following is the code i use to congiure my amplify

    return session.isSignedIn;
  } catch (e) {
    print("Error checking authentication: $e");
    return false;
  }
}

class MyApp extends StatelessWidget {
  final bool isAuthenticated;

  const MyApp({Key? key, required this.isAuthenticated}) : super(key: key);

  @override

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?

@Jordan-Nelson @khatruong2009 Any suggestions guys how can i overcome this error?

Jordan-Nelson commented 6 months ago

Can you share the contents of these two files?

The error message is saying that the function getApplicationLocalSupportDirectory() isn't defined. It should be defined in path_provider_local.dart. I would like to see the contents of your local files to see if that function is defined.

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

amantiwari-18 commented 6 months ago
  • 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
