I am new at flutter, I published a package on pub.dev but due to some issues, I have to remove or rename it from there (https://pub.dev/). I want that no one can see it by searching it. I 'Discontinued' it from pub.dev, but it is still visible from advance search? Is there any way to hide it permanentally or remove it?
Although packages always remain published, it can be useful to signal to developers that a package is no longer being actively maintained. For this, you can mark a package as discontinued. So as you did, a discontinued package remains published and viewable on pub.dev, but it has a clear DISCONTINUED badge and doesn’t appear in pub.dev search results.
That is all you can do as far as I know!
