@jason-simmons:

The recipe library that uploads logs set both FLUTTER_LOGS_DIR and FLUTTER_TEST_OUTPUTS_DIR to the same path
(see https://flutter.googlesource.com/recipes/+/refs/heads/main/recipe_modules/logs_util/api.py#27)

So tools should be able to use either one. (I don't know why both of these variables exist given that they appear to be identical)

AFAICT the flutter_drone recipe used to run the test linked above is not using the log upload library. The recipe itself would need to be modified in order to get that functionality.

That's unfortunate, as flutter_drone is used over 100+ times.
