* or an array to represent a route with query parameters (e.g. `['site/index', 'param1' => 'value1']`).
* @param string|null $scheme the scheme to use for the URL (either `http`, `https` or empty string
* for protocol-relative URL).
* If not specified the scheme of the current request will be used.
* @return string the created URL
