delete the old pub page ?

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 ...

Compare the old pub.dartlang.org page for temp_flutter_webview_plugin with the current flutter_webview_plugin page linked in the issue. Start by determining whether the old page can be removed or corrected, and consider the task done when the obsolete page no longer causes confusion about this repository.
