What steps will reproduce the problem?

1. create a new project,
2. open pubspec,
3. add Ace and run 'pub get'.

I see the following:
Run Tools > Pub Get to install packages
Pub get failed, [1] Resolving dependencies...
The null object does not have a getter 'isNotEmpty'.

NoSuchMethodError: method not found: 'isNotEmpty'

I can't reproduce this with the attached package and Dart 1.8.5. Is it possible that one of the dependencies had a malformed pubspec and has since been updated not to have such a pubspec?

I am the maintainer of that package, and I have also seen this error one time roughly a week ago (it subsequently went away after an SDK upgrade I think? I'm on dev channel). From the stack trace it looks like it is parsing the description field of a devDependency? Is that required? The docs on pub.dartlang.org say:

description
Required for packages that are hosted on pub.dartlang.org.

I wouldn't expect the devDependency of the hosted package to require this field, since devDependencies are not part of a using packages dependency graph right? Could that be the problem though?

The hosted package has this in its pubspec:

dev_dependencies:
  ace_js:
    path: js

The ace_js package is used internally for testing and examples, but intentionally not exposed to the applications using the package which source their own js files. Its pubspec only contains a name field.

thanks

Ah, that's issue #1238. It should be fixed in the latest 1.9 builds.
