Exit code 64 when running on Windows

From conversation in slack.

When trying to run clj -M:cljd flutter I get the following output

The problem happens because of this

PS C:\Users\Franco\Desktop\flutter\acme> flutter.bat pub run C:\Users\Franco\Desktop\flutter\acme\.clojuredart\analyzer.dart

If I change it like this

https://github.com/frankitox/cd-64/commit/d5f225db7b160579ae4affa0de50463c832b2eeb#

It works (although I hit another new error)

Start with the cljd.build entry point and the .clojuredart/analyzer.dart command shown in the report. Reproduce clj -M -m cljd.build flutter on Windows and compare the generated flutter.bat pub run invocation with the linked working change. Done means dependency setup and type-information dumping complete without pub exit code 64.
