Hey @mostakahmedmullick , can you provide a small sample so i can reproduce the issue on my end?

context.loaderOverlay.show(); await Future.delayed( const Duration(seconds: 3)); context.loaderOverlay.hide(); Navigator.pushNamed( context, RouteNames.results); return;

When you show, then hide overlay then push to another page, pop the page, the overlay will not show a second time.
