viewTransition
If set to true, the router will wrap the resulting navigation in a document.startViewTransition() call. If ViewTransitionOptions, route navigations will be called using document.startViewTransition({update, types}) where types will be the strings array passed with ViewTransitionOptions["types"]. If the browser does not support viewTransition types, the navigation will fall back to normal document.startTransition(), same as if true was passed.
If the browser does not support this api, this option will be ignored.
