Currently the launchDevTools command will try to launch Chrome-for-Linux on ChromeOS. I believe it needs to launch the default browser in that case.

I don't know if this is the best way, but I think it needs to do something like this:

final isCrOS = Platform.isLinux && File('/dev/.cros_milestone').existsSync();
if (isCrOS) {
  Process.start('x-www-browser', ['https://www.google.co.uk/']);
} else {
  // Current way
  Process.start(_executable, [
    'https://www.google.co.uk/', /* + Chrome flags? */
  ]);
}

@jacob314 can you confirm this sounds right? Webdev is doing is own launching, and will require Chrome for Linux (because it needs to pass flags), but for non-Webdev we expect to always use the native browser?
