Luckily this class didn't actually need to extend its superclass, it
only implements the interface. So we can change `extends` to
`implements` and that's close enough, while allowing the class to be
mixed in again.

* Avoid abbreviations

* Sample code for AppBar.leading

* Add a test for OverflowBox/FractionallySizedBox

* Minor wording improvements in the text.

The words "note that" here don't really contribute to the flow.

* Revert "Revert "Run reload asynchronously so that multiple devices can reload in parallel. (#22693)" (#23598)"

This reverts commit 0b68068d.

* Fix refreshViews so it sends app-wide(rather than per-isolate) service request.

Sending per-isolate request caused dead-lock in the engine in case of more-than-one ui isolate.

* Added '--check-for-remote-artifacts' option for Flutter Doctor.

This option takes a Flutter engine revision and issues HEAD requests to
determine whether or not artifacts for the provided engine revision are
available from cloud storage. This functionality is needed for the Dart
SDK autoroller to avoid creating a PR to roll the engine into the
framework while artifacts haven't finished building, which would cause
Cirrus tests to fail.

Previously there was no way to add this flag when searching for
Isolates.

One of the devicelab tests is broken after this commit - rolling to last known good commit while I investigate.

Fixes #21825

Allow heroes to fly across navigators and restrict Cupertino nav bars to per navigator by default (#23322)

* Run reload asynchronously so that multiple devices can reload in parallel.

Bug #1: These didn't work with directional alignments, due to an error
in the types of the constructor arguments.

Bug #2: Pretty sure RenderSizedOverflowBox never worked at all. As
soon as I wrote a test for it, the test showed that there was a
fundamental bug in its performLayout method: it didn't set
parentUsesSize, but it immediately tried to use the child's size.

* Improve documentation

* Potential performance win in hit testing

Rather than copying the list every time we access `path`, this just
exposes it as an `Iterable`. People who want to copy it can use
`toList()`.

(This isn't a breaking change since code that expects a `List` is
still going to get one.)

* Enforce the Oxford Comma.
