What does the -d flag stand for when running Flutter Build_Runner?

Question

We use a lot of freezed packages and utilize them with json serializable stuff in a project. The command we use to auto generate is:

flutter pub run build_runner watch -d

I can't remember why I needed to use the -d command line option, but I remember that it wasn't working properly without it. What I want to know is what does the -d actually do? I haven't been able to find what its function is.

EDIT: I actually found the answer running flutter pub run build_runner --help and I found that -d is just shorthand for the command line option --delete-conflicting-outputs

Answer 1

The -d option is to help target the device such as flutter run -d <device_id>.
