I can't get the imports to work !

I need the function: uploadData for this function:

  final downloadUrl = await uploadData(storagePath, pdfSaved);

however when I try to get the import give me errors:

import '../../flutter_flow/upload_data.dart';

the target uri does not exist, I have tried to change the path and whatnot , it seems that I need to add a component but I can't seem to find what it is any help ??
