Invoking msbuild with runInShell makes handling path escaping more
error-prone, and substantially increases the chances of running into
maximum path limits. This replaces the direct call with a .bat wrapper
that calls vsvars64.bat then msbuild, and uses relative paths within the
script to keep command lengths short.

Fixes https://github.com/flutter/flutter/issues/32792

This will fix a failure in dev/bots/analyze-sample-code.dart when using
the tip of tree Dart SDK.

This reverts commit faec4ca3.

This reverts commit 841286d6.

* Deprecates `BinaryMessages` in favor of a default instance of `BinaryMessenger`, called `defaultBinaryMessenger`
* Platform channels use the `defaultBinaryMessenger` for their binaryMessenger default argument.

Replacing the algorithm for finding the first focusable item in the focus tree. Somehow it was a kind of gibberish before, and really didn't work or make sense.

* Adding sample and animation for Flow widget

* Updated dart templates for layout in API docs

* Updated the sample code for a clearer example.

* make clean

This also fixes up some indentation in some
bulleted lists.

Splits Xcode validation out of the iOS validator and into a stand-alone
validator, and groups the CocoaPods validator with that top-level
validator instead of the iOS validator. iOS now validates only the
iOS-specific tools (e.g., ideviceinstaller).

Reorganizes many of the associated clases so that those that are used by
both macOS and iOS live in macos/ rather than ios/. Moves some
validators to their own files as part of the restructuring.

This is the macOS portion of #31368

Updates documentation and non-public API to use American spellings for
consistency with the rest of the codebase.

No changes to behaviour... other than how it's spelt.

Corects a bnuch of typeos throuhgout teh Fluter codebsae.

Made use of the `misspell` tool:
https://github.com/client9/misspell

Adds a new macosPrefix, which serves the same purpose as iosPrefix but
for macOS plugins.

It is not yet used by the tooling, but this allows for plugins to start
to be written using it in preparation for tooling support for plugins.

Part of #32718

* Implement ExpandIcon custom color, expandedColor, and disabledColor

* Update to use pumpAndSettle instead of hard-coded duration

* Update colors to unfocused state, added dark mode test to active state

* Fix Colors.white30 doc opacity value

* Add links to Material Design specifications to color, expandedColor and disabledColor

* Update API docs to reference dark theme material page

This adds a maintenance script that will allow us to "unpublish" a release: basically remove it from the cloud storage so that we're no longer serving it from the website.

Obviously, gsutil access to the cloud storage server is required for this to function.

It was easy to miss the reference to the top-level `imageCache`
property before.  This calls out the property a little more
explicitly.

The dart analyzer fails to warn about missing returns in function expressions due to a bug that has been
fixed but not yet rolled into Flutter (see
https://dart-review.googlesource.com/c/sdk/+/100301).  So it failed to catch that https://github.com/flutter/flutter/pull/33217 accidentally introduced a call to `testWidgets` that passed it a synchronous callback.

They are newer and faster to start

Fix a bug where holding down on text selection caused the handles to flash. The fix was to only update selection when it actually changed.

I forgot to add `onChunk` to them in #33092

This is necesasry to integrate CocoaPods, since CocoaPods operates
primarily on the workspace rather than the project.
