Can you post your build.yaml with the configuration for drift_dev? What database file did you include there. Can you check whether that file does indeed only contain a single database class (so not none and not multiple)?

Is there a database in that file? Could you run dart run drift_dev identify-databases in your project directory and post the output?

Well... silly me. I found the problem. turns out that my path is incorrect supposed "lib/src/database/database.dart", i forgot the 'src'. and that solves it. Thanks man! found the problem after running your suggested command "dart run drift_dev identify-databases"
