code_transformers 0.2.9+2 is incompatible with analyzer < 0.26.0

[matdavies]

code_transformers 0.2.9+2 was released on 19th August and requires analyzer >= 0.26.0, but angular requires analyzer < 0.25.0. A simple dart project with the following pubspec.yaml file fails to build to js:

name: angular_testing
description: A sample web application
dependencies:
  angular: any
  dart_to_js_script_rewriter: any
transformers:
- angular
- dart_to_js_script_rewriter

The exception that occurs is:

Build error:

This can be fixed by adding the following to pubspec.yaml:

dependency_overrides:
  code_transformers: 0.2.9

Not sure if this is an issue for AngularDart or for code_transformers.
