[material_ui] Add awaitNotRequired annotation to material_ui - #12622

…tter#12618)

This converts CircleController, PolygonController, and PolylineController 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.

…lutter#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.

…mit author check to pre-push-skill (flutter#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. 
- @reidbaker 
---
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 (`eval-author@example.com`).
- 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.
