This reverts commit 3fd36200.

* Create new TextField attribute to control maxLength behaviour

* Create test case for maxLinesIncrementalHeight

* fix maxLinesIncrementalHeight set method

* fix editable_test.dart

* Just introducing some proposed API additions, renaming to expands

* Pass minLines and expands through to child widgets and validate

* minLines can't be null, and expands can't be true when maxLines is 1

* Implement minLines and maxLines height sizing logic

* Simplify minLines validation logic

* expands parameter proof of concept

* min/max mixup bug fix, and tests work with expands false

* Test expands=true cases, and fix textPainter.height being out of date

* Test all behavior matrix cases

* min/max assertion more strict, can't be equal

* Tests work that were missing expands serialization

* Action sheet tests no longer fail due to rounding error

* TextFieldFocus test no longer mysteriously fails

* TODOs for making expands nullable. Will depend on how Expanded wrapping works

* Expanded growth happens when expanded is true and maxLines is null

* Test Expanded wrapper

* No more overflow when wrapped in Expanded

* Docs improvements

* expands can be null

* Simplify error cases to support existing behavior

* Docs examples and other docs cleanup

* Expansion up to perfectly meet the parent size

* Fix analyze null error

* Fix test after move to nullable expands

* minLines defaults to null

* expands is now exclusively for expanding to parent height and not growth between min and max

* _layout rewritten to handle max height. Need to fix prefix tests and
reenable expands

* Tests for textfield overflowing parent

* layoutLineBox is documented and private

* expands works in new _layout

* _layout return numbers seem to perfectly match original _layout

* inputWidth comment after trying it out and failing tests

* Fix analyze errors

* WIP prefix/suffix do affect height

* Prefix/suffix and icons affect height, tests pass, but I'm still visually verifying identical to original

* Tall prefix test that verifies pixel perfect layout

* Fix overflowing edge case and test it

* Clean up comments, old code, and todos

* Changing _expands causes relayout. Wasnt able to figure out how to test though...

* Clean up code review comments

* Fix misalignment when tall prefix and border, and clean up related test

* Simple code review cleanup

* Bring back inputWidth to _layout method

* Fix rounding errors showing up in mac tests

* Fix flake by reordering tests. Without this, the dreaded intrinsicwidth flake is reproducible 50% of the time on my machine.

* Fix more rounding error mac tests

This removes references to SemanticsSortOrder, which was removed a long time ago.

In anticipation of changing a lot of the focus code, I'm adding some tests for the FocusScope.

As a result, I was able to find and fix a bug where there was an incorrect assert.

I also added some more documentation.

Several of the tests enforce what I think is incorrect behavior related to passing focus off when the widget tree gets rebuilt without focus nodes that were previously there, but I'm not going to change that behavior in this PR.

I also renamed focus_test.dart to focus_scope_test.dart to be more in line with our naming conventions.

* update readme for LUCI

* Update README.md

* Fix for post submit on cirrus

* Wrap test.main with a custom processor
* Report test results to bigquery table

flutter_shared was used to package the icudtl.dat file, but that data is
now embedded inside libflutter.so

* doc update

This switches the Cirrus macOS images to use Mojave, since Cirrus has deprecated the High Sierra images.

When running git update-packages, if the goldens repo is dirty, the
flutter tool currently crashes and logs the failure from git pull.

This adds a check for a dirty git client and emits a friendlier error
message in the case where it's not clean, and avoid the crash by
catching the NonZeroExitCode exception and rethrowing as toolExit
instead.

Fixes: https://github.com/flutter/flutter/issues/28915

* fix some formatting issues

* address review comments

* fix indent
