patch function Null safety

Future<Response> patch(
  1. Uri url,
  2. {Map<String, String>? headers,
  3. Object? body,
  4. Encoding? encoding}
)

Sends an HTTP PATCH request with the given headers and body to the given URL.

body sets the body of the request. It can be a String, a List<int> or a Map<String, String>. If it's a String, it's encoded using encoding and used as the body of the request. The content-type of the request will default to "text/plain".

If body is a List, it's used as a list of bytes for the body of the request.

If body is a Map, it's encoded as form fields using encoding. The content-type of the request will be set to "application/x-www-form-urlencoded"; this cannot be overridden.

encoding defaults to utf8.

For more fine-grained control over the request, use Request or StreamedRequest instead.

Implementation

Future<Response> patch(Uri url,
        {Map<String, String>? headers, Object? body, Encoding? encoding}) =>
    _withClient((client) =>
        client.patch(url, headers: headers, body: body, encoding: encoding));
