I went (http://www.dartlang.org/articles/io/) to get this example:

import 'dart:io';

_send404(HttpResponse response) {
  response.statusCode = HttpStatus.NOT_FOUND;
  response.outputStream.close();
}

startServer(String basePath) {
  var server = new HttpServer();
  server.listen('127.0.0.1', 8080);
  server.defaultRequestHandler = (HttpRequest request, HttpResponse response) {
    final String path = request.path == '/' ? '/index.html' : request.path;
    final File file = new File('${basePath}${path}');
    file.exists().then((bool found) {
      if (found) {
        file.fullPath().then((String fullPath) {
          if (!fullPath.startsWith(basePath)) {
            _send404(response);
          } else {
            file.openInputStream().pipe(response.outputStream);
          }
        });
      } else {
        _send404(response);
      }
    });
  };
}

main() {
  // Compute base path for the request based on the location of the
  // script and then start the server.
  File script = new File(new Options().script);
  script.directory().then((Directory d) {
    startServer(d.path);
  });
}

When I run the code, it looks like it's working, but it doesn't actually listen on port 8080. It seems to just do nothing. When I try to set a breakpoint on the first line of the startServer function, the server output says:

dart --enable-checked-mode bin/server.dart
