extractedUrl : The initial target URL after being parsed with UrlSerializer.extract().
finalUrl : The extracted URL after redirects have been applied. This URL may not be available immediately, therefore this property can be undefined. It is guaranteed to be set after the RoutesRecognized event fires.
trigger : Identifies how this navigation was triggered. -- 'imperative'--Triggered by router.navigateByUrl or router.navigate. -- 'popstate'--Triggered by a popstate event. -- 'hashchange'--Triggered by a hashchange event.
