Changed 5 dependencies!
It downgrades angular!!!!!
< angular 0.0.7 (was 0.9.10) (15 newer versions available)
If I change my dependencies for browser:
dependencies:
browser: ">=0.10.0+2 <0.11.0"
Results in:
> analyzer 0.13.5 (was 0.12.2)
analyzer_experimental 0.8.6
angular 0.0.7 (15 newer versions available)

I'm using Dart 1.3.0!!! so - this is the latest version for today. I don't know what pub upgrade is doing here but it does not manage dependencies...
Any hints?
[Update]
As a workaround I change my dependencies to
dependencies:
polymer_elements:
git: https://github.com/ErikGrimes/polymer_elements
polymer_ui_elements:
git: https://github.com/ErikGrimes/polymer_ui_elements
angular: any
# git: https://github.com/angular/angular.dart
# Incompatible version constraints on html5lib:
# - angular depends on version >=0.9.2 <0.10.0
# - polymer depends on version >=0.10.0 <0.11.0
lawndart: any
validate: any
http_utils: any
Directly linking to GitHub solves almost everything. Except Angular!!!!
Resolving dependencies... (50.0s)
< angular 0.0.7 (was 0.9.10) (15 newer versions available)
> barback 0.12.0 (was 0.11.1) (1 newer version available)
cipher 0.6.0 (1 newer version available)
< di 0.0.24 (was 0.0.34) (10 newer versions available)
Very frustrating, it took me almost 3h to get the latest polymer version and angular is still 15 versions behind.

Here is a discussion about a similar experience https://groups.google.com/forum/#!searchin/angular-dart/0.0.7/angular-dart/PnvkUudHulg/ZtM3Y8xH_ugJ
I guess you should add version constraints on every dependency where weird (too old) versions are fetched until pub upgrade complaints that it is not able to resolve the dependencies.
This could help to find the culprit.
The pub deps command was added in Dart 1.4 to show which package dependes on which other packages.
