Summary:
X-link: react/react-native#60005

Upgrade formatter dependencies and retained locks to Prettier 3.10.0, with the compatible CLI and source changes needed for a self-contained upgrade prefix. Preserve runtime behavior, Flow types and parser/style policy; exclude the retained Yjs bundle with noformat instead of reformatting its generated body.

Metro review: Looks good

Risk: low · Commit: 5a5e416 · 6 commands run

This PR bumps the root Prettier devDependency from 3.9.4 to 3.10.0. In two untranspiled metro-file-map worker files, it drops the semicolon after a // prettier-ignore'd class field. Prettier 3.10 would otherwise move the ; in front of the Flow type comment (#plugins; /*: ... */), which detaches the comment from the field. Without the semicolon the field ends by ASI, because constructor follows on a new line. Flow, lint, a repo-wide format check and the worker tests all pass, and both files load in plain Node.

No findings.

Verified

• ✅ node_modules/.bin/prettier --stdin-filepath packages/metro-file-map/src/worker.js < <base version of worker.js> — Prettier 3.10.0 rewrites the base line to #plugins; /*: ReadonlyArray<MetadataWorker> */, which explains why the semicolon was dropped
• ✅ yarn prettier --check . — Whole repo is clean under 3.10.0
• ✅ node -e "require('./packages/metro-file-map/src/worker.js'); require('./packages/metro-file-map/src/plugins/dependencies/worker.js')" — Both untranspiled files parse and load in Node without the semicolons
• ✅ yarn eslint packages/metro-file-map/src/worker.js packages/metro-file-map/src/plugins/dependencies/worker.js
• ✅ yarn jest --no-watchman packages/metro-file-map/src/__tests__/worker-test.js — 10 tests passed
• ✅ yarn typecheck — Flow: No errors

Not run: No benchmark: this is a formatter devDependency bump plus two punctuation-only edits, with no runtime cost. The yarn.lock change swaps one devDependency version and adds no new packages. Changes to package.json and yarn.lock still need the usual Meta import.
