* Look up breakpoints rather than relying on magic numbers

* Make breakpoint comment more obvious

Samsung Galaxy S9 is not an emulator and installation of
the release packages with 'flutter run --release' should be possible.

* Add `--dry-run` option to `flutter format` sub command

* Add `--set-exit-if-changed` option to `format` sub command

* Add `--machine` option to `format` sub command

* Make variable names to be not shorthand: cmd -> command

Changes:

- Move the SemanticsConfiguration update from RenderToggleable to each subclass, so that Switch can use toggled.
- Add image, liveRegion, toggled properties to Semantics, SemanticsConfiguration, SemanticsNode
- Added semanticsLabel and excludeFromSemantics to Image (the latter so that we avoid creating a semantics node)
- Added onDismiss semantics action which maps to the modal escape on iOS and dismiss action on Android.
- Added dismiss and liveRegion to snackbar widget
- Updated custom painter semantics to handle image, liveRegion, toggle
- Updated relevant tests to use correct flag/action

Added five InputBorder properties to InputDecoration etc so that apps can control the appearance of an InputDecorator's border:  errorBorder, focusedBorder, focusedErrorBorder, disabledBorder, enabledBorder.

* fixed segmented control golden test

* fixed segmented control golden test

* made the comments more explanatory

* changed comment, wrapped tests with if statements so they only run on MacOS

* changed formatting

* added width and radius fields to TextField; to do: tests and Material defaults

* weak warnings

* added tests

* added default cursor width; changed default EditableText width

* only run golden file tests on linux

* changed goldens version

* actually changed goldens.version

* style changes

* small fixes

* added default material cursor color

* changed goldens.version

* changed goldens version again

* changed goldens.version again (3)

* added todo

* deleted whitespace

The trailing whitespace detector wasn't handling file deletes very well (at all, really).

This filters the set of files grepped to only include files that exist.

Also, clarified the failure message to make it more obvious what the failure is when the grep finds results.

* Fix the checksum verification to be more sensitive

* update packages

* Tell flutter to quit directly

Fixes #19208.

* Tweak comment

We don't actually care if we're on linux, we care only if the lcov
tool is available. We check for that explicitly just below.
Additionally there is code below which indicates that lcov is available
for macOS. Before this change that code would never execute.

* re-enable lint unnecessary_const

* remove trailling whitespaces

* remove unnecessary const (after merge)

* Change material refresh indicator onRefresh signature from Future<Null> to Future<void>.

* Update authors.

* Explicitly name void argument.

RenderAndroidView is responsible for sizing and displaying an embedded
Android view.
AndroidView is responsible for creating and disposing the Android view
and is using RenderAndroidView to display it.

* Changed duration

* Fixed column width for ios build error messages

* fixed a couple things

* fixed a couple things

* accidental changes

* added spaces

* added spaces

* Added test for default snackbar duration

* Fixed link:

* Final commit

* Final commit2

* Actual final commit

* Remove uses of deprecated constants
* Change int.parse to int.tryParse where appropriate

The verbosity change is to help track down timeouts that currently look like:

```
C:\Windows\Temp\flutter sdk>call bin\flutter.bat config --no-analytics
Checking Dart SDK version...
Downloading Dart SDK from Flutter engine c5a63d28bf3735569c8187753bc490d8351a8363...
Unzipping Dart SDK...
Updating flutter tool...
```

Follow-up to https://github.com/flutter/flutter/pull/18562, which passed Travis before the check was added.

Checks only changed source files (C++, Dart, Java, ObjC) for trailing whitespace.

With a fix of a path being printed relative instead of absolute.
