Currently dev_dependencies are excluded from release builds. However,
this is not implemented fully for iOS and macOS yet and has caused
issues. So until the iOS team is ready and can fully implement this
feature, we're removing it for iOS and macOS.

Fixes flutter#170119,
flutter#167377.

…#171017)

Some of these request paths are not guaranteed to be requested by the
time the test is finished, which makes this test somewhat flaky. We
don't really care about verifying these requests specifically anyway, so
just don't track them or compare them to our expectations.

This fixes flutter#171025

Skia is removing the constructors which default to the FreeType font
scanner. This will allow Skia to simplify dependencies.

…ialValue" (flutter#170805)

## Description

This PR renames the DropdownButtonFormField constuctor parameter 'value'
to 'initialValue'.
See
flutter#170050 (comment)
and
flutter#170050 (comment)
for some context.

## Related Issue

Fixes [DropdownButtonFormField retains selected value even after setting
value to null](flutter#169983 (comment))

## Tests

Adds 2 tests (one to validate the deprecated parameter can still be
used, one for the dart fix).
Updates many (renaming the confusing parameter).

…ifferent from the original one (flutter#168654)

This PR changes the Hint uses topLeft alignment when maintainHintSize is
false
> code
```dart
buildTextField() {
  return const Center(
    child: TextField(
      decoration: InputDecoration(
        hintText: 'hint',
        maintainHintSize: false,
      ),
    ),
  );
}
```

1) Lots of data file updates
1) Added command line arg to just scan one file to speed up development

1) Started removing trailing asterisks from c style comments

This change reverts the following previous change:
## Motivation

We'd like to let users opt-in to experimental features so that they can
give early feedback while we iterate on the feature. For example:

Example feature flags:

1. Android sensitive content:
flutter#158473. When enabled, Flutter
will tell Android when the view contains sensitive content like a
password.
2. Desktop multi-window. When enabled, Flutter will use child windows to
allow things like a context menu to "escape" outside of the current
window.

### Use case

Users will be able to turn on features by:

* **Option 1**: Run `flutter config --enable-my-feature`. This enables
the feature for all projects on the machine
* **Option 2**: Add `enable-my-feature: true` in their `pubspec.yaml`,
under the `flutter` section. This would enable the for a single project
on the machine.

Turning on a feature affects _both_ development-time (`flutter run`) and
deployment-time (`flutter build x`). For example, I can `flutter build
windows` to create an `.exe` with multi-window features enabled.

## How this works

This adds a new
[`runtimeId`](https://github.com/flutter/flutter/pull/168437/files#diff-0ded384225f19a4c34d43c7c11f7cb084ff3db947cfa82d8d52fc94c112bb2a7R243-R247)
property to the tool's `Feature` class. If a feature is on and has a
`runtimeId`, its `runtimeId` will be [stamped into the Dart application
as a Dart
define](https://github.com/flutter/flutter/pull/168437/files#diff-bd662448bdc2e6f50e47cd3b20b22b41a828561bce65cb4d54ea4f5011cc604eR293-R327).
The framework uses this Dart define to [determine which features are
enabled](https://github.com/flutter/flutter/pull/168437/files#diff-c8dbd5cd3103bc5be53c4ac5be8bdb9bf73e10cd5d8e4ac34e737fd1f8602d45).

### Multi-window example

flutter#168697 shows how this new
feature flag system can be used to add a multi-window feature flag:

1. It adds a new [multi-window
feature](https://github.com/flutter/flutter/pull/168697/files#diff-0ded384225f19a4c34d43c7c11f7cb084ff3db947cfa82d8d52fc94c112bb2a7R189-R198)
to the Flutter tool. This can be turned on using `flutter config
--enable-multi-window` or by putting `enable-multi-window: true` in an
app's .pubspec, under the `flutter` section.
2. It adds a new
[`isMultiWindowEnabled`](https://github.com/flutter/flutter/pull/168697/files#diff-c8dbd5cd3103bc5be53c4ac5be8bdb9bf73e10cd5d8e4ac34e737fd1f8602d45R7-R11)
property to the framework.
3. The Material library can use this new property to determine whether
it should create a new window.
[Example](https://github.com/flutter/flutter/pull/168697/files#diff-2cbc1634ed6b61d61dfa090e7bfbbb7c60b74c8abc3a28df6f79eee691fd1b73).

## Limitations

### Tool and framework only

For now, these feature flags are available only to the Flutter tool and
Flutter framework. The flags are not automatically available to the
embedder or the engine.

For example, embedders need to configure their surfaces differently if
Impeller is enabled. This configuration must happen before the Dart
isolate is launched. As a result, the framework's feature flags is not a
viable solution for this scenario for now. For these kinds of scenarios,
we should continue to use platform-specific configuration like the
`AndroidManifest.xml` or `Info.plist` files.

This is a fixable limitation, we just need to invest in this plumbing :)

### Tree shaking

Feature flags are not designed to help tree shaking. For example, you
cannot conditionally import Dart code depending on the enabled feature
flags. Code that is feature flagged off will still be imported into
user's apps.

1. Android and iOS support
2. set application locale.

flutter#168437 was reverted as it broke
google3. This adds a `FeatureFlags.allEnabledFeatures` property to the
Flutter tool, which google3 will override to inject its custom feature
flag logic.

…th sharp corners (flutter#171351)

Fixes flutter#170593.

The problem was caused by errors in the path building algorithm that
handles sharp corners and unequal width/height.

(Honestly the errors for the `scale_sign` part and the transform matrix
part were kind of embarrassing. I don't know what I was thinking when I
wrote them.)

This PR adds a `--profile-microtasks` flag to `flutter run` that can be
used to set [the Flutter Engine's `--profile-microtasks`
switch](flutter#170690).

Updates the widget previewer to properly handle previews defined across
a workspace. This is effectively equivalent to displaying previews from
multiple individual projects, which required a fairly significant rework
to properly support:

 - resolving asset paths to the right project
 - loading assets across projects in the workspace
 - tracking changes to pubspec.yaml files across the workspace

While making this change, it became apparent that we don't need to
explicitly list the assets from the various projects explicitly in the
scaffold's pubspec.yaml as they're automatically pulled in by adding
those project's as dependencies and using the `package/$ASSET_PATH`
format to load the assets from the scaffold. This allowed for the
removal of a significant amount of logic related to building the
scaffold's pubspec.

Fixes flutter#169268

…get preview scaffold (flutter#171602)

This allows for developers to perform a hot restart on the preview
environment in the case they get into a bad state.

This change adds a `hotRestartPreviewer` method to the `widget-preview`
DTD service registered by the Flutter Tool, which is invoked by the
previewer.

…lutter#171641)

Tracks the following metrics:

- Overall launch time with/without generating the widget preview
scaffold
- Time from detecting a file change within the tracked project to
actually loading the updated previews into the previewer

Fixes flutter#166418
