I have installed a Chrome dev editor tool, created a dart web app, and I unable to run it I get this error when I try to run it image

Then I tried to get the packages "Pub Get" and get this error image

I installed the dart via brew still the same.

I don't know what exactly causes your first error message but the 2nd is caused by an old Dart SDK version. Dart before about 1.8.0 isn't able to parse version constraints using the shorthand notation ^

    In the [chrome web store](https://chrome.google.com/webstore/detail/chrome-dev-editor-develop/pnoffddplpippgcfjdhbmhkofpnaalpg?hl=en) it says that it was last updated on 10th September 2015. – stwupton Dec 16 '15 at 17:22
  • Chrome Dev Editor is no longer being actively developed (but this does not means that it is deprecated). Your information is not correct. –  Dec 16 '15 at 18:10
