Some links broken, is there an errata?

[DryToa5t]

Hello, I noticed that a lot of the documentation links are broken. Like the appbar document link, https://flutter.dev/flutter/material/AppBar-class, leads to a 404 page along with the scaffold and a lot of the links that point to flutter documentation.

I know I can look through the documentation and find what I need, that isn't an issue. As a person new to coding I would like to know if some of those widgets and such have been deprecated or are no longer used in favor of something else.

By tutorial standards this course is a bit "old" and I am wondering if there is an errata or something similar that explains what has been changed?

for the specific link you mentioned > https://api.flutter.dev/flutter/material/AppBar-class.html

For all others, simply go to Material Library either on Flutter Docs or Dart websites.
