* Use (processors-1) for test runs (test defaults to processors/2)

* Add missing import 🙄

This optimization resulted in app still running with old kernel file.

This reverts commit 617e8f65 as it
breaks deps-processing on Windows.

This reverts commit 751c083f.

Our buildbots need to be upgraded to a newer version of the Android SDK.

See https://github.com/flutter/flutter/issues/23171

This is just a shorthand for
Scrollable.ensureVisible(tester.element(finder))

Fixes #8185

We're no longer using Appveyor.

Updating the --wrap-column help message to reflect reality.

Fixes flutter/flutter#22062

Make it possible to disable TextField's default handlers for tap and long press. If enableInteractiveSelection is false then taps no longer move the text caret and long-press no longer selects text and shows the cut/copy/paste menu. Accessibility is similarly limited.

This re-lands 3c56e6c7 on top of a new Dart SDK that contains new mixin syntax fixes.

Simple convenience function if users create flutter projects in custom folder structures and but want to specify a custom project name.

`FlutterDevice.views` is limited by a filter. Pipe this filter up as an
option for the commands that instantiate `FlutterDevice`s. This is the
first change necessary for the CLI tooling to target specific isolates
(#22009).

More work needs to be done after this patch.
* Isolate names are dynamically generated and change every restart.
* This just filters views, not background isolates (`VMService.isolates`).

Dispatch a Flutter.Navigation event each time navigation occurs.

--track-widget-creation=false to
--track-widget-creation=true
but not when switching from
--track-widget-creation=true
to
--track-widget-creation=false

due to the surprising behavior of Gradle @Optional inputs.

If the scroll is out of range for any reason (for instance, changing scroll physics or manually messing with scroll position), the spring simulation causes the scroll position to slingshot towards the end. Also, before this change, `end` was unused.

* enable lint prefer_void_to_null

* replace last Null by void

* Added sample code for BottomNavigationBar widget [#21136]

* bottomnavigationbaritems made single line

* Fix form field validate method being called if form field is disabled

Behavior remains the same for multiline TextFields. This behavior already happens on iOS and Android, but not desktop. #23014

* Make it easier to Add2App for iOS

* Use local engine if xcconfig says so

* newline
