Invalid argument(s): Minimum version ("2.0.0-dev.23.0") must be less than maximum ("2.0.0-dev.16.0").

[nailgilaziev]

first this appears when I try to pub serve web.
I install dart version 1.24.3 and web served.

next is flutter run

mac:letsvote_mobile n$ flutter run
Running "flutter packages get" in letsvote_mobile...      
Invalid argument(s): Minimum version ("2.0.0-dev.23.0") 
must be less than maximum ("2.0.0-dev.16.0").

And huge log after that.

Who can help, how to run this example?

This is an issue with the flutter sdk (I think)

a similiar issue was reported here: apptreesoftware/flutter_google_map_view#16

I was able to upgrade my Flutter SDK to the latest "dev" channel to fix it.
You may also want to try the "master" channel (as reported by the user in that issue)
