How do I know if a lib is server side, client side or both?

Question

dart:html is a client side library, whereas dart:io is a server side library because this is obvious... but what about a funky lib get from http://pub.dartlang.org/packages ? Server side, client side, both ? How do I know for sure ?

Answer 1

Hopefully the library documents whether it depends on dart:html or dart:io. If not, the only real way to know is to try it.
