 * - `path` is a string that uses the route matcher DSL.
 * - `component` a component type.
 * - `name` is an optional `CamelCase` string representing the name of the route.
 * - `data` is an optional property of any type representing arbitrary route metadata for the given
 * route. It is injectable via {@link RouteData}.
 * - `useAsDefault` is a boolean value. If `true`, the child route will be navigated to if no child
 * route is specified during the navigation.
