Trying to use this library but having an issue when trying to get a CastDevice

CastDevice device = CastDevice(name:info.name,host: info.address,port:info.port,type: '_googlecast._tcp');

This gives me the error:

Invalid argument(s): "<" expected at 1:1

Any ideas?

In order to get information about your device, the library makes an HTTP GET request to http://${host}:8008/ssdp/device-desc.xml. The result you're getting is an invalid response.

I recommend printing info.address and then making the GET request in your browser, substituting the printed address into the above URL. If you still can't determine the cause of the issue, I recommend you post the response here.

From the browser, I can easily get info from /setup/eureka_info but never from /ssdp/device-desc.xml

Okay I've done some digging and found some unofficial documentation (https://rithvikvibhu.github.io/GHLocalApi/#device-info-eureka-info-get) - it looks like the library can be adapted to use /setup/eureka_info (which works on my Android TV device too - out of interest are you using an Android TV or Chromecast?)

For reference, the URL I've crafted that can act as a substitute is: http://${host}:8008/setup/eureka_info?params=name,version,detail.icon_list,device_info.manufacturer,device_info.model_name

I'll try and sort out a PR to the repo. Not sure how active the maintainer is.

Didn't know about the eureka_info way to get the device's info. Seems to be a better fit for this use case, since it's JSON and not (annoying) XML and we can also specify which params we would like to have returned.

Updated the code to use eureka_info instead of device_info.

[holyspidoo]

For model name and friendly name, there is no need for eureka_info since we already have the attributes bundle to decode? You can look at how I did it in:
cast_device

Also, just a heads up, I've noticed that POST requests to Eureka device dont' seem to work with HTTP library, I had to use DIO to get those to work (for GET it doesn't matter). Took me far too much time to find out :)
