• WARNING: dart:mirrors support in dart2js is experimental,

•      This implementation of mirrors is incomplete,

Just use the pub build command from the darteditor todo this. Bin is your serverside code.

Tools > pub build

or do it without --all

--all
Optional. Builds all of the buildable directories (benchmark, bin, example, test, and web) that are present.

You can also try 'pub build web' you only need to create web files and the bin or serverside files don't need to be build or translated to js.

https://www.dartlang.org/tools/pub/cmd/pub-build.html

Hopefully this will help.
