dartdocgen trying to generate documentation for pub package

[Austin Cummings]

Hi all,

I am trying to generate docs for my application but I can't because of the oracledart package using a native extension scheme: "dart-ext:nativewrappers". I get the following error. I am hoping someone could tell me how to get around this.

Thanks

Error: Library not found 'dart:nativewrappers'.

import 'dart:nativewrappers';

Unfortunately, I don't think you can. Dartdocgen uses the dart2js compile-time mirrors, so it can't run on something that dart2js can't handle. A workaround is to comment out the import of the problem package(s) when generating docs, but that's pretty ugly.
