This converts GroundOverlayController and TileOverlayController to Swift in the `_sdk*` packages.

The remaining Obj-C code will be migrated in a series of follow-up PRs to keep the scope of each PR reasonable for review.

The conversion process was:
- Initial conversion via Gemini, with explicit instruction to keep the structure the same.
- Side-by-side manual review of the old and new versions of the files.
- Manual fixes and improvements.

This includes test changes beyond what we would normally expect for a language conversion PR (e.g., name changes from dropping the prefix) because the conversion to Swift exposed a latent issue in the tests. Several tests had a pattern where a helper method was creating a local `mapView` instance, using it to construct the subcontroller under test, and then returning that subcontroller—at which point the map view goes out of scope. The subcontrollers have weak references to the map view, so it can be deallocated before the test actually runs, and doing so causes the tests to fail (as many operations in the subcontroller no-op when the map view is nil). In cases where the helper is only used once, it can be inlined; in cases where it's used repeatedly we can instead return multiple values and keep the map view alive.

…12581)

Currently sync back pr for batch release is created as soon as the batch release PR merges.

This can be a problem if the release workflow runs on the release branch fails and someone accidentally merge the sync back pr without knowing. It will be extremely hard to clean up in this case.

The PR changes it that the sync back pr is only created when release finishes successfully.

After this change, if release fails, we can simply delete the release branch and re trigger the batch release workflow to try again.

Merging this PR carry a risk if there is bug in the new code in release_from_branch workflow. If you don't see a sync back pr the next time batch release, let me know and i can help clean up and fix.

…ness skill (#12628)

This came up as part of #12624 I
noticed that the pre-push skill passed my code but linux analyze failed.
It was because I didnt realize that this checkout (I have 2) didnt have
git hooks installed.

Agent authored description 
Updates the `check-readiness` skill to verify that Git pre-commit hooks
(`script/githooks`) are configured in the repository (`core.hooksPath`).
If unconfigured or pointing to an unexpected path, it provides
actionable instructions to run `script/githooks/bin/install_hooks.dart`.

Includes unit test coverage in `check_test.dart`.

… and fix TextEditingController leaks (#12228)

This PR fixes the CupertinoIcons not being included in the actual examples and some leaks of TextEditingControllers,
which were things i noticed while fixing up cross imports (which by themselves have been fixed since then)

Part of flutter/flutter#187645

Since the Code Freeze period is still ongoing, I did not chance the version for cupertino_ui in the changelog yet.

This is work towards dart-lang/sdk#59226

The lint rule use_super_parameters has a bug such that it didn't previously report these cases. But they will be reported soon.

## Pre-Review Checklist

Test exempt, as this code is covered by existing static and runtime checks.

Updates `go_router_builder` dependency constraint for `analyzer` to `<15.0.0` to support Analyzer 14.

Ports flutter/flutter#190206 to `material_ui` following flutter/flutter#188444.

Fixes flutter/flutter#190205.

This change prevents an older asynchronous `SearchAnchor.suggestionsBuilder` request from replacing the results of a newer request.

It assigns an incrementing ID to each suggestions request and only applies the result when it still represents the latest request.

…mit author check to pre-push-skill (#12624)

This work started by adding evals to make sure the changlog backticks work did not regress. Then I discovered that the agents.md file I updated didn't work if the camera_android_camerax folder was opened which was the documented project-oneshot plan. 

When authoring those evals I ran into issues branching the workspace. google/skills_lint.dart#3 addresses updating the skill to work in more situations. 

This pr also adds some shared utilities and a script to verify that eval commits are not pushed.

Agent authored description. 
Enforces the repository-wide requirement that code references in `CHANGELOG.md` must be enclosed in backticks, and adds verification tooling to prevent pushing evaluation test commits.

## Changes

### 1. CHANGELOG Backtick Enforcement
- Updated `pre-push-skill/SKILL.md` to verify `CHANGELOG.md` formatting following the ecosystem contributing guidelines.
- Linked package `AGENTS.md` to repository root `AGENTS.md`.
- Added Eval 5 (`setup_user_facing_docs_change.dart`) to evaluate and assert detection of unquoted code references in `CHANGELOG.md`.

### 2. Eval Commit Prevention & Tooling
- Created `evals/tool/check_eval_commits.dart` CLI tool using `package:args` and idiomatic exit code handling to verify that outgoing branch commits contain no forbidden evaluation author credentials (`[email protected]`).
- Added Step 3 ("Check for Evaluation Test Commits") to `pre-push-skill/SKILL.md`.
- Extracted shared author credentials and commit helpers into `evals/tool/test_utils.dart` and migrated all eval setup scripts to use it.
- Added Eval 6 (`setup_eval_commit_failure.dart`) to evaluate and assert rejection of evaluation test commits.

## Verification
- `flutter test test/skills_evals_test.dart`
- `flutter test test/validate_skills_test.dart`
- `dart analyze .agents/skills/pre-push-skill/ evals/`
- `dart run evals/tool/check_eval_commits.dart --remote=origin`
- Ran full evaluation suite (Evals 1–6) with subagents in isolated worktrees.

Updates `pigeon` `dev_dependency` constraint to `^27.3.2` across first-party packages to ensure compatibility with `analyzer: ^14.0.0` during `pub downgrade` resolution.

- Removes conflicting standalone `test` dev_dependencies from plugin packages that already depend on `flutter_test`.
- Updates `pigeon` constraint to `^27.3.2` across all 36 first-party plugin packages.
- Fixes `in_app_purchase_storekit` to rename `SK2ProductMessage.description` to `localizedDescription` for Swift Pigeon 27.0+ compatibility.
- Regenerates Pigeon bindings across all platforms.
- Bumps package patch versions and updates `CHANGELOG.md` files.

**Ports over #12206 which landed on the `m3e_migration` feature branch.**

### Original PR description

Work towards flutter/flutter#187899

Moves all M3 templates and their generated code to gen_defaults/temporarily_excluded before we begin migrating.

This way when we migrate each component, we can first move the template and its respective generated code into the new directories, edit the template, and re-generate the code. This will make it easier to review changes to the templates and validate the generated output.
