I think the problem is the line:

final String flutterRoot = path.dirname(path.dirname(path.dirname(path.fromUri(Platform.script)))); not playing well with the memory file system

Thanks, looks like Platform.script returns a data URI when executed with pub run test 😕 , looking for a testing friendly alternative

I don't see an easy way around the data:uri path when executed with pub run test, ended up allowing the test to override the path to the versions file so that flutterRoot is not evaluated in test. Sadly it means that the test now covers one less thing (the file path).

Yeah, I think we hack around this in the flutter tool by checking the scheme, and then doing a regex in tests. Which isn't ideal.
