Add support for keeping parser diagnostic expectations in the source
snippets they describe. Expectations are written as caret markers and
diagnostic comments, and regenerated from the parser's actual
diagnostics before comparison.
This keeps parser recovery expectations close to the code under test and
removes the need to maintain offset-based `assertErrors` lists by hand.
The updater also removes existing expectation markers before writing the
canonical form, so marked snippets can be refreshed in place.
Migrate recovery parser and class parser tests to the new
`assertExpectedDiagnostics` helper, including no-error cases where an
unmarked snippet is the expected canonical form.
Update `test_runner` to exclude `/pkg/analyzer/` from searching static
error expectations.

This CL enables the primary constructors feature by default in Dart 3.13.
The primary constructors feature is a brevity feature. There are no new semantics, but it allows us to express declarations in a less verbose way.
This feature allows one constructor and a set of instance variables to be specified in the header of a declaration.
Currently a declaration with a constructor and some fields is written as:
```dart
// Current syntax.
class Point {
int x;
int y;
Point(this.x, this.y);
}
```
With a primary constructor, we would write the above as:
```
class Point(var int x, var int y);
```
If a primary constructor needs an initializer list or a body, they can be
specified inside the class using the `this` body syntax:
```dart
class Point(var int x, var int y) {
this : assert(x >= 0) {
print('Point created at $x, $y');
}
}
```
As part of this feature, you can also use the `new` and `factory` keywords to
declare constructors in the class body without repeating the class name:
```dart
class Point {
int x, y;
// Equivalent to Point(this.x, this.y)
new(this.x, this.y);
// Equivalent to Point.origin()
new origin() : x = 0, y = 0;
// Equivalent to factory Point.clone(Point other)
factory clone(Point other) => Point(other.x, other.y);
}
```

Move PackageConfigFileBuilder into the analyzer_testing public API and
deprecate the copy exposed from package:analyzer. The builder is only
used by test infrastructure, so keeping it in analyzer_testing makes the
ownership clearer and avoids exposing test-only utilities from analyzer.
Update the builder API to accept a rootFolder instead of a rootPath.
This lets callers pass the resource-provider folder directly, so the
generated rootUri is derived from the same file-system abstraction that
created the test files. This avoids accidentally passing POSIX paths
where resource provider paths are required, such as on Windows.
Update existing test utilities and callers to import the new library and
pass Folder objects. Remove the production analysis server dependency on
the builder by emitting the temporary plugin package config JSON
directly.

The Flutter Widget Preview feature is currently implemented within
Flutter Tools, which is responsible for detecting widget preview
annotations in the user's project. When previews are detected, the
Flutter Tool injects code generated based on the detected previews into an artificial widget_preview_scaffold project and performs a hot reload to render updates to the preview set in the scaffold application.
`package:analyzer` is currently being used to detect previews, but this comes with a significant amount of memory overhead. Since widget
previews are mostly being used from within IDEs which already have an
active analysis server, moving widget preview detection into the DAS
will remove the need for creating an additional analysis context in the Flutter Tool itself.
This change includes the initial work to move widget preview detection
into the DAS. It utilizes a pull-based mechanism, where the Flutter Tool listens for file system events and then queries the DAS using the `dart/textDocument/getFlutterWidgetPreviews` and `dart/workspace/getFlutterWidgetPreviews` LSP methods.
Each reported preview contains some generated code based on the annotation used to define the preview. This code has all constants from the original annotation evaluated to either primitive values or constant expressions with namespaces applied to each symbol, allowing for the Flutter Tool to inject this code directly when updating the generated code in the scaffold project.

These tests cover all the functionality of the API summary tool.
Note that since the `ApiDescription` constructor requires an
`AnalysisContext`, I added a public `contextCollection` getter to the
`PubPackageResolutionTest` base class.
There are a few loose ends I intend to address in follow-up CLs. They
have been noted in TODO comments:
- Annotate when classes are `abstract`, `final`, or `interface`.
- Move `pub_package_resolution.dart` out of
`package:analyzer_testing/src` (so that when I publish this as a
separate package, that package won't be dependent on private
implementation details of `package:analyzer_testing`).

Changes the test logic in `analysis_server` and `analyzer_testing` so
that after printing `To accept the current state, expect:`, it prints
diagnostic codes in their proper camelCase format.
Also removes some bogus code from
`pkg/analyzer_testing/lib/analysis_rule/analysis_rule.dart` that
erroneously suggested passing a `name:` parameter to the top level
`error` function. This function does not accept any parameter called
`name`.
Previously, only tests in `pkg/analyzer/test` printed the diagnostic
codes correctly.

Fixes https://github.com/dart-lang/sdk/issues/62234 by making the

with `double width` and `double height` parameters on the Preview
constructor. But this has been changed to use a `Size` object, and
`Size` is written in 'dart:ui'. So to write a test that uses `Size`, the
test now needs proper access to 'dart:ui', and we should not write
'package:ui/ui.dart' in our test cases. These changes are in

Adjusts the logic in the lint `Registry` class so that lint names are
matched in case-insensitive fashion. For the most part this is
accomplished by adding calls to `.toLowerCase()` inside the `Registry`
class, preserving its API.
For the `enabled` method, preserving the API would have been a pain (I
would have had to translate the keys in the `ruleConfigs` parameter to
lower case). So instead I added an assertion to verify that the keys
were lower case, and pushed the responsibility to the callers to
create lower case keys.
This paves the way for a follow-up CL that will translate diagnostic
codes to `lower_snake_case` conventions.
It also solves a longstanding problem with the mixed case lint rules
`no_runtimeType_toString`, `prefer_for_elements_to_map_fromIterable`,
`prefer_iterable_whereType`. Previously, the user had to carefully
imitate the capitalization of the lint rules when specifying them in
the `analysis_options.yaml` file, even though `// ignore:` comments
for the lints matched in case insensitive fashion. With this CL, the
lint rule names in `analysis_options.yaml` are matched in case
insensitive fashion as well.
