Bad state: Unable to generate package graph

[Aristidios]

I get this error when I try to run flutter pub run build_runner build --delete-conflicting-outputs in my local package inside my project

Unhandled exception:

Hello ! I had the same problem today, it seems that by removing generate: true in the flutter section the problem disappears. I hope I helped you.
