delete the old pub page ?

[ghost]

you have an old pub page that points to this repo:
https://pub.dartlang.org/packages/temp_flutter_webview_plugin

you newest pub page is this one:
https://pub.dartlang.org/packages/flutter_webview_plugin

So you might want to try to delete the old one. Its confusing ...

Deleting packages isn't supported (members of the Dart team can manually delete packages though)
The common way is to just publish an updated README.md under the old name and with a text that thos package is not maintained anymore and a link to the new package.
