Why do you need this?

[blois, 2013/01/17 21:03:30]

I was under the impression that this is required for the 'native' keyword.

The goal is for dart:chrome to be generated identically to
dart:html/indexed_db/svg/web_audio, so I'm assuming that it needs the same
access.

Basically the chrome application APIs use a different IDL format than the rest
of the APIs, and Sasha is going to be working on supporting those.

[ahe, 2013/01/17 22:06:55]

I think this is different from dart:html, etc.

As it is right now, I do not think it is safe to use the native keyword in this
library, and I'm concerned that doing so may conflict with the other APIs.

Unless you have strong evidence that wrapping is not going to work, I'd really
prefer if you do not enable the native keyword in this library.

       || libraryName == 'dart:indexed_db'
       || libraryName == 'dart:svg'
       || libraryName == 'dart:web_audio') {
     library.canUseNative = true;
   }
 }
