head function Null safety

Future<Response> head(
  1. Uri url,
  2. {Map<String, String>? headers}
)

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<Response> head(Uri url, {Map<String, String>? headers}) =>
    _withClient((client) => client.head(url, headers: headers));
