openUrl method Null safety

Future<HttpClientRequest> openUrl (
  1. String method,
  2. Uri url
)

Opens a HTTP connection.

The HTTP method is specified in method and the URL to use in url.

The Host header for the request will be set to the value Uri.host:Uri.port from url (if url.host is an IP address, it will still be used in the Host header). This can be overridden through the HttpClientRequest interface before the request is sent.

For additional information on the sequence of events during an HTTP transaction, and the objects returned by the futures, see the overall documentation for the class HttpClient.

Implementation

Future<HttpClientRequest> openUrl(String method, Uri url);
