head function
Sends an HTTP HEAD request with the given headers to the given URL.
This automatically initializes a new Client and closes that client once the request is complete. If you're planning on making multiple requests to the same server, you should use a single Client for all of those requests.
For more fine-grained control over the request, use Request instead.
Implementation
Future<http_request.Response> head(String url,
{Map<String, String>? headers}) async {
return await http_request.get(Uri.parse(url), headers: headers);
}
