head method
Sends an HTTP HEAD request with the given headers to the given URL.
If timeout
is not null the request will be aborted if it takes longer
than the given duration to complete, and the returned future will complete
as an error with a TimeoutException.
For more fine-grained control over the request, use send instead.
Implementation
@override
Future<$http.Response> head(Uri url,
{Map<String, String>? headers, Duration? timeout}) =>
_sendUnstreamed('HEAD', url, headers, null, null, timeout);
