* clarify widgetsapp docs

* Rename shadowed param, update doc

* pageContentBuilder

Reverts flutter/flutter#24111 as https://skia-review.googlesource.com/c/buildbot/+/167200 has been deployed.

We need to wait the fix in
https://skia-review.googlesource.com/c/buildbot/+/169724
to land in order to enable the rebase merge method again.

TBR: goderbauer

We'll land this quickly without waiting for presubmit checks
to unblock our engine roller.

* Move integration tests to use vm_service_lib
* Turn off debug logging that was accidentally committed
* Run update-packages --force to fix checksum for new dev dependency
* Trim trailing whitespace

This converts existing ## Sample code samples to {@tool sample}...{@end-tool} form.

Also:
1. Fixed a minor bug in analyze-sample-code.dart
2. Made the snippet tool only insert descriptions if the description is non-empty.
3. Moved the Card diagram to before the code sample.

* Document module pubspec

* update doc on plugin template

* clarify language

We have templates now.
