Problem

Attempting to fetch a flutter-depending package using dart pub prints a confusing error message:

[flutter_eng_cycle_times] dart pub get
Resolving dependencies...
Because every version of dio_http_cache from git depends on flutter any from sdk which is forbidden, dio_http_cache from git is forbidden.
So, because flutter_eng_cycle_times depends on dio_http_cache from git, version solving failed.

Flutter users should run `flutter pub get` instead of `pub get`.
exit code 69

I originally thought it was relating to my "git" dependency or the fact that it was "flutter any" rather than a specific flutter version or something.

What the real error is is the last line. It's telling me that because this package depend on Flutter I need to use a different flavor of pub to fetch it. :(

This might be solved by #3196

We are still a bit unsure if that is the right fix - the logic of the solver is not clear to us here.

Closing this for now, assuming it is fixed.
