You're using test 0.12.3+9, which was released ten months ago. This is fixed in the latest release.

[scheglov]

Well, apparently there is nothing better than 0.12.3+9. When I attempt to use one of the published version, pub does not allow me.

You need to determine what other packages' constraints are causing test to be held back to an old version—pub upgrade --verbose is currently the best tool for this.

Please stop re-opening this issue; there's nothing we can do in test to help, and we can continue the discussion when it's closed.

[scheglov]

pub upgrade --verbose looks strange - it does not even try to get the version I ask it for.

[nex3]

Oh, I think I know what's going on here. You're using a 1.18 dev version, so you're getting pushed back to versions of test that (incorrectly) didn't have an upper SDK constraint. We need to release a new version of test; this is tracked by #437.

[scheglov]

Good to know. Thank you!
