Not sure if this is in Flutter's domain or if it's a Google Search issue, but just in case...

I was looking for documentation on the DropDownMenuItem class, so I searched flutter.io:

Clicking on the first result gave me this error screen:

Looks like the first page was trying to take me to https://docs.flutter.io/flutter/material/DropDownMenuItem/DropDownMenuItem.html
but the page I was looking for was actually at https://docs.flutter.io/flutter/material/DropdownMenuItem-class.html

I searched through a few more pages in the search results, and did not find the second link.
