Just curious.. would restarting the build fix things or is it more complicated than that?

[Rexios80]

@rrousselGit All tests pass locally. Not sure what's wrong with CI.

[rrousselGit]

It could be that your changes break tests only under some special conditions.

[Rexios80]

@rrousselGit I'm confused how the get and upgrade build actions are even different. I don't see any checked in pubspec.lock files so shouldn't running pub get and pub upgrade result in the same dependency resolution?

[rrousselGit]

Hum that's a good call. Some of my repos may have mistakenly ignored the lock file

It probably doesn't matter here though

[rrousselGit]

Let's go!
Thanks for this :)
