Accessing resources inside polymer elements

[Metronome]

How do you read files from a compiled dart file?

I have a method like this:

void _getImages() {
  List<String> images = new List<String>();
  //var u=path.fromUri("web/images");
  //print(u);
  var f = new Directory("web/images");
  f.list(recursive: false, followLinks: false)
      .listen((FileSystemEntity entity) {
    images.add(entity.path);
  });
  _createSlideElements(images);
}

However I get an error when running this in chrome: 

Unsupported Operation Platform._operatingSystem

What is the correct way of setting this up?  Eventually I want to be able to pass the path into the component through the template.

To quote the api docs.

https://api.dartlang.org/apidocs/channels/be/dartdoc-viewer/dart:io

"The I/O library is used for Dart server applications, which run on a stand-alone Dart VM from the command line. This library does not work in browser-based applications."

Well that does end up explaining things.  Thank you.

Inside the Chrome browser, you can use the filesystem API, which gives
you a virtual file system to store things in. This is dead as a W3C
proposal, and will not be implemented on other browsers.

If you want access to the real file system on the machine, Chrome
web apps can access the extra chrome apis, which exit the browser's
sandbox and give you access to the underlying system.
