Tests are failing on a clean clone

[robert-j-webb]

Hey not sure if this is my machine or something (am I using the wrong SDK)? Anyway, here's the steps to reproduce:

$ git clone git@github.com:ReactiveX/rxdart.git
$ cd rxdart
$ flutter pub get
$ flutter test

And the output:

And my flutter version:

Flutter 2.5.2 • channel stable • https://github.com/flutter/flutter.git

Engine • revision 6ac856380f

Should the tests be ignored? Or is it possibly something flakey? Thanks :)
