Code Review

This pull request updates the documentation for several widgets in the cupertino_ui and material_ui packages by adding missing "Widget of the Week" YouTube video links. It also bumps the package versions to 1.0.1 and updates their respective changelogs. I have no feedback to provide.

Hey @piedcipher thanks for porting these over so quick!
I forgot, @youtube does not work outside of flutter/flutter, but is should soon: dart-lang/pub-dev#9490 (comment)

We worked around this for now in these packages by just embedding the link to the widget videos in the text, e.g.:

packages/packages/cupertino_ui/lib/src/activity_indicator.dart

Line 22 in a3e763e

/// Learn more about [CupertinoActivityIndicator] on the [Flutter YouTube channel](https://www.youtube.com/watch?v=AENVH-ZqKDQ).

On another note, these packages are using a new batch release process to prevent the bottleneck of constant merge conflicts with the pubspec and changelog. Instead, you can create a pending changelog, and then we compile them together when the release goes out. There are instructions on adding the pending changelog file in flutter/flutter#188444 under "The flutter/packages changelog file". You can use the tool to create one, or you can create the file yourself using the template under pending_changelogs/

Thanks! I’ve done all of that. Appreciate the help!

Code Review

This pull request adds links to Widget of the Week YouTube videos within the API documentation for CupertinoSliverNavigationBar, Badge, CarouselView, SearchAnchor, SearchBar, and SegmentedButton. It also adds corresponding changelog files for the cupertino_ui and material_ui packages. There are no review comments, and I have no feedback to provide.

Confirmed all the links are pointed to the correct videos!
