Fixes https://github.com/Dart-Code/Dart-Code/issues/1421.

Previously, we had a scroll_perf drive test but we were not exercising
it on our device lab. This helps us tracking issues like:
https://github.com/flutter/flutter/issues/24782

This PR does two things:

- It allows BottomAppBar to have a custom shape even when it doesn't
  have a notch.

- It adds AutomaticNotchedShape, an adapter from ShapeBorder to
  NotchedShape.

* Support using flutter with specific version

* Set min supported version to 1.2.1

Integrate Strut: Add StrutStyle, expose Strut API, wire up strut with dart:ui, Roll engine 31a7f4d..e7eb1c8 (7 commits) (#26332)

Includes a breaking change to dart:ui ParagraphStyle where lineHeight is renamed to height for consistency with TextStyle.

* Expose "center" on CustomScrollView

* Also support anchor

Allow the theme to provide these values to Chips

* Ensure Shrine app repsects the platform toggle from Gallery options

* Retrigger CI

* Retrigger CI again

The new parameter defines the color of the checkbox's check mark. Default is (still) white.

Additionally, fix the status bar color for the login screen

Closes #26034 

Expose elevation on chips and allow for it to be customized by the developer.

* Don't send accept/reject if compilation never started.

Ensure that we wait for reject's response since that is async operation.

Fixes https://github.com/flutter/flutter/issues/27120.

* Fix analysis errors

* Rename flag. Ensure we raise it on first compilation too.

Create a slider shape for custom track, tick mark, and overlay painting, for the material slider.

* Remove stray extra space

* Add ImageStreamCompleter.hasListeners (and cleanup)

This is mostly just some cleanup of stuff I ran into, but it makes
`hasListeners` protected on `ImageStreamCompleter`, because otherwise
there's no way to track if listeners are registered or not.

* Address review comments
