createClient abstract method
Creates and configures a http.BaseClient instance using the
configuration that corresponds to the logical name specified
by name.
Each call to createClient is guaranteed to return a new
http.BaseClient instance. It is generally not necessary to dispose
of the BaseClient as the HttpClientFactory tracks and disposes
resources used by the BaseClient.
If no name is provided, the BaseClient will be configured using
the default configuration.
Implementation
http.BaseClient createClient([String? name = Options.defaultName]);
