close method

void close ({bool force: false })

Shuts down the HTTP client.

If force is false (the default) the HttpClient will be kept alive until all active connections are done. If force is true any active connections will be closed to immediately release all resources. These closed connections will receive an error event to indicate that the client was shut down. In both cases trying to establish a new connection after calling close will throw an exception.

Implementation 

void close({bool force: false});
