6 years ago The version of packages you are using are quite old (quiver is now on 0.29.0+1).
Please utilize the latest Dart2-compatible packages and use a pub upgrade. Feel free to open another issue if the problem persists, but I'm nearly certain you are just using outdated packages.
I have just upgraded to Dart version , Now I am unable to do the build, getting below error msg. Dart VM version: 2.0.0-dev.67.0 (Tue Jul 3 18:17:07 2018 +0200) on "macos_x64". I am using Chrome browser for running my applications.
