My Flutter app requires code generation for multiple reasons, such as mock generation for tests, or both Floor and Isar persistence back-ends require generation. I achieve this by executing flutter packages pub run build_runner build --delete-conflicting-outputs. I'm getting the message about the command being deprecated. However I'm wondering what command am I supposed to run instead.
Currently I'm using:
$ flutter packages pub run build_runner build --delete-conflicting-outputs
Deprecated. Use `dart run` instead.

This always re-generates the files.
First try:
$ dart run build_runner build --delete-conflicting-outputs

The problem is that this didn't regenerate any files whatsoever. No bueno.
Second try:
$ dart packages pub run build_runner build --delete-conflicting-outputs

I looked at a few other SO entries, but I don't have any errors so far, and my CI/CD works, however I'd like to migrate until the command totally deprecates.
dart run build_runner build --delete-conflicting-outputs
This changed with 2.1.3 of the build_runner package
