Is there any way to trigger Builder method in ShelRoute

Question

  return ShellRoute(
  builder: (context, state, child) {
    return LoadingOverlay(
      child: RoutingBottomNavigationBar(
        paths: paths,
        child: child,
      ),
    );
  },
  routes: _appRoutes,
);

is there any way to trigger builder method in ShellRoute or rebuild the widget which is returned in the build method from another widget
