Yeah, relative path can be tricky.
Note, I don’t think they’re required by I enclose my path in single quotes:
path: ‘../../libs/dbutils.dart’ (Have you got the file name right?)
Also, you’ve got ..lib/
I’m thinking that should be ../lib/
Further, it’s relative to the current location that is the directory containing that very file, pubspec.yaml. You have to deduce carefully how many ‘parent folders’ (i.e. double dots: .. ) you’re going to need and such.
