Makes the analysis options changes described in
https://github.com/flutter/flutter/issues/178827:
- Adding
[omit_obvious_local_variable_types](https://dart.dev/tools/linter-rules/omit_obvious_local_variable_types)
- Adding
[specify_nonobvious_local_variable_types](https://dart.dev/tools/linter-rules/specify_nonobvious_local_variable_types)
- Adding
[specify_nonobvious_property_types](https://dart.dev/tools/linter-rules/specify_nonobvious_property_types)
- Adding
[type_annotate_public_apis](https://dart.dev/tools/linter-rules/type_annotate_public_apis)
- Removing
[always_specify_types](https://dart.dev/tools/linter-rules/always_specify_types)
After those changes, makes the following repo-wide changes:
- `dart fix --apply` in all packages and in script/tool/
- `dart format` in all packages and in script/tool/
- `update-excerpts` repo tooling command to update excerpts based on the
changes to their sources
Also updates the min Flutter/Dart SDK version to 3.35/3.9 for the
following packages, to avoid `analyze` failures in the `N-2` legacy
analysis run due to what appears to be a 3.9 change in what the Dart
analyzer continues to be an obvious local type in loop iterations:
- go_router
- google_fonts
- google_identity_services_web
- google_maps_flutter_web
- local_auth_platform_interface
- metrics_center
- multicast_dns
- pigeon
- rfw
- shared_preferences
- two_dimensional_scrollables
- vector_graphics_compiler
- mustache_template
- path_parsing
Because this is causing a significant amount of format churn already, I
took this opportunity to update the repository tooling to a min Dart SDK
of 3.8 (the N-2 stable version, so the earliest version we need the
tooling to support) to pick up the new format style, so the amount of
automated formatter change is higher in script/tool/ than in the
packages.
This does contain two manual changes (other than the repo tooling min
version):
-
d700b45c7d
changes `dynamic` to `Object?` in a few places where `dynamic` caused
analyzer warnings under the new rule set.
- Updates the repo tooling to ignore `.dart_tool/` when looking for
unexpected local `analysis_options.yaml` files, to fix issues running
the repo tool's `analyze` command locally based on recent changes in
`dart` behavior.
This does not include any CHANGELOG or version updates; even though we
normally version any changes to production code, mass automated changes
like this aren't worth the churn of releasing. This includes changes to
lib/example/main.dart and to README.md excerpts; while the style changes
will be user-visible on pub.dev, it's fine for those changes to wait for
the next release of each package.

This fixes two issues with the format command's language resolution handling:
- It was not running `pub get` in sub-packages, so for the rare case of sub-packages with different min versions than their enclosing package, format behavior was inconsistent, and incorrect in CI where the tree starts clean.
- It was not detecting stale resolution, which was annoying when formatting locally since it's not uncommon to have last run `pub get` for some package before the last min SDK bump for that package, causing local formatting to be incorrect. This was especially problematic when doing min SDK bumps for the entire repo after `stable` releases.
It also fixes the related problem that `fetch-deps` was not running `pub get` in sub-packages, which would have prevented the pigeon issue in CI, but not locally. Even with `format` fixed, we still want everything fetched in `fetch-deps`.
The parsing does depend on internal implementation details of Dart, but we don't expect those to change frequently, and if it does we can update the detection logic as necessary. The failure mode should either be to throw, which we'll catch during the roll, or to run `pub get` more than necessary, which would just be an optimization issue rather than a correctness issue.
Includes `pigeon` format changes, since now CI is enforcing the correct format instead of the incorrect format that was checked in.

## Pre-Review Checklist
[^1]: Regular contributors who have demonstrated familiarity with the repository guidelines only need to comment if the PR is not auto-exempted by repo tooling.
Per guidance from legal on current preferred practice, remove "All rights reserved" from all LICENSE files and header blocks, and update the repo tool check accordingly.
Consolidates the code to find all changed file paths into the `PackageLoopingCommand` class that is the base of almost all of the repo tooling commands. This in a preparatory PR for a future change to allow each command to define a list of files or file patterns that definitively *don't* affect that test, so that CI can be smarter about what tests to run (e.g., not running expensive integration tests for README changes).
A side effect of this change is that tests of almost all commands now need a mock `GitDir` instance. This would add a lot of copy/pasted boilerplate to the test setup, and there is already too much of that, so instead this refactors common test setup:
- Creating a memory file system
- Populating it with a packages directory
- Creating a RecordingProcessRunner to mock out process calls
- Creating a mock GitDir that forwards to a RecordingProcessRunner
into a helper method (using records and destructuring to easily return multiple values). While some tests don't need all of these steps, those that don't can easily ignore parts of it, and it will make it much easier to update tests in the future if they need them, and it makes the setup much more consistent which makes it easier to reason about test setup in general.
Prep for https://github.com/flutter/flutter/issues/136394
Updates the repo tooling to Dart 3, now that the N-2 version has Dart 3, which allows us to use Dart 3 features (e.g., records) going forward.
To allow the update:
- Removes `break` commands from `switch`es (all done automatically with `dart fix --apply`)
- Replaces mocking of `ProcessResult` with just creating an actual `ProcessResult` since it's a `final` data class and thus can't (but also doesn't need to be) mocked.
For iOS and macOS move fetch deps from explicity running `pub get` and `pod install` to instead run `flutter build x --config-only` which smartly fetches deps and lays down the required native pieces. I didn't guard it on whether certain files are present since the command already has similar guards, and runs pretty fast if the native code has already been generated.
This fixes an issue where `pod install` is run before the Flutter native bits and migrations are run.
Fixes issues seen in the Flutter roll https://github.com/flutter/packages/pull/5792#issuecomment-1876103613

Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "Flutter":
In Podfile:
Flutter (from `Flutter`)
Specs satisfying the `Flutter (from `Flutter`)` dependency were found, but they required a higher minimum deployment target.

Unable to "pod install"
```
Caused by https://github.com/flutter/flutter/pull/140478
Adds `fetch-deps` support for:
- iOS/macOS dependencies, using `pod install`
- Dart package dependencies, using `pub get`
To make avoid doing extra work in the Dart dependencies step when using this with `*_platform_tests` CI, also adds flags for all of the other platforms, and adds a flag that allows skipping Dart dependencies for any package that doesn't have an example supporting any requested platform. This means that we can pass, e.g., `--windows --supporting-target-platforms-only` to only fetch Dart packages for packages with examples that will be build during the build-and-drive Windows tests.
Adds this as a new step in every platform tests CI task, and in the standard analyze step, so that we will pre-fetch Dart packages (and for iOS/macOS, pods). This won't yet fully eliminate later network access (see https://github.com/flutter/flutter/issues/131204), but will give us early warning on any major failures, such as pub being entirely unreachable from the bots.
- These are marked as an infrastructure step; we'll have to see if this ends up being confusing in practice. If `pub` resolution fails for legitimate reasons, such as a PR that tries to require a version of a package that doesn't exist or that has conflicts, this will cause a failure that is marked as infra. My assumption is that the much more common case is going to be that it is actually an infra failure.
