The library 'package:loading_overlay/loading_overlay.dart' is legacy, and should not be imported into a null safe library.

Thanks for opening the issue - This library should have been migrated to null safety in 0.3.0. I will try reproduce. Are you using the latest (3.0.0)

?

I wasn't using latest version , but hold on when i tried to use latest version still there was error that the package update is not out yet like that i am sorry but I can't remember it exactly , so i used older version . After some suggestions from stackoverflow , sorry to bother 🙂
