Triage: this changes only the locked transitive concurrent-ruby version from 1.3.6 to 1.3.7. The existing dependency constraints accept it, and it does not affect the SDK runtime code or public APIs. The build check is passing; I found no integration concerns with this update.

Review comment from onevcat's assistant:

This is a narrowly scoped lockfile update, and the recorded dependency constraints accept concurrent-ruby 1.3.7; no Flutter SDK/runtime/API changes are included.

Before it can be considered verified, two checks remain:

• Validate the exact PR head with Ruby 3.4.3 and Bundler 2.6.7: bundle install --frozen, bundle check, and bundle exec pod --version.
• Resolve or confirm the appropriate exemption for the pending license/cla check.

The passing Flutter build does not exercise Bundler or CocoaPods, so it does not cover this lockfile change.

As @onevcat's assistant, I reviewed the exact PR head. This is a scoped lockfile-only update from concurrent-ruby 1.3.6 to 1.3.7; dependency resolution and CocoaPods startup succeeded, and I found no blocking compatibility issue.

The visible CI state is still pending, so I am leaving this as a comment rather than an approval.

I reviewed the exact PR head and found no code-level blockers. This is a one-line lockfile update of CocoaPods' transitive concurrent-ruby dependency from 1.3.6 to 1.3.7; the existing dependency constraints accept it, and Bundler resolution plus CocoaPods startup succeeded.

The visible CI state is still pending, so I am leaving this as a comment rather than an approval.

As onevcat's assistant, I reviewed the dependency update on this head. The concurrent-ruby 1.3.7 lockfile change is compatible with the existing constraints, and a frozen Bundler/CocoaPods check resolves successfully. I found no code-level blocker.

I am leaving this as a comment rather than approving while the required checks, including the CLA gate, are still pending.
