Flutter SDK
Fixes of mine are merged into flutter/flutter, the Flutter SDK itself. Each one is a signed commit in the official repository. This page is the record, and every line on it links back to the thing it claims.
Framework work is slow and public. A fix starts as an issue somebody else filed, sometimes years earlier, and ends as a signed commit in a repository that ships to millions of apps. The highlight is 26 August 2026, when one of these commits was the newest on master.
Merged
Newest first, as recorded on 28 August 2026. The release named is the first tagged Flutter release that carried it.

The window
On 26 August 2026 commit e6aa89e merged at 15:10:17 UTC and stayed the newest commit on master until the Skia roll landed at 18:10:03 UTC. For that span the repository homepage listed gabrimatic in the latest-commit row, and archives I do not run recorded it. In order:
| UTC | Moment | Record |
|---|---|---|
| 15:10:17 | Merged | e6aa89e through pull request #185789. The commit lands on master, closing an issue open since February 2019. From this moment the repository homepage lists gabrimatic in the latest-commit row. |
| 17:46:12 | archive.today | archive.ph/2s6VE. The homepage, captured. It answers 429 to automated clients, so open it in a browser rather than fetching it. |
| 17:59:20 | Arquivo.pt | arquivo.pt/wayback/20260826175920/https://github.com/flutter/flutter. The homepage recording responds. Its deep links for the commit, the pull request and the author history return 404 until the crawl is indexed. |
| 18:01:09 | Ghostarchive | ghostarchive.org/archive/dF1bK. The homepage, nine minutes before the window closed. The replay shows gabrimatic in the latest-commit row with the commit title and e6aa89e. A WARC copy is kept in the record repository. |
| 18:03:38 | Software Heritage | swh:1:snp:b8d0cfb296a79c4f93256d694fb77d8e0bd604da. The repository itself, not the homepage: a full snapshot of the source tree, with the commit reachable as a revision record. |
| 18:10:03 | Overtaken | Pull request #191810, the Skia roll. The next commit lands and becomes the newest on master. The window closes. |

Verify
None of this has to be taken on trust. The commits are in a repository I do not control, signed by a key that is not mine.
Fetch a commit from the official repository, import GitHub's web-flow public key, and run git show --show-signature. It reports a good signature from GitHub <noreply@github.com> over the parent and tree it records.
git fetch https://github.com/flutter/flutter.git e6aa89eea34850cb1fd25d9f4d0b2fad379b00bf
curl -s https://github.com/web-flow.gpg | gpg --import
git show --show-signature --format=fuller FETCH_HEADThe record repository keeps the raw commit object of the milestone, its patch, a copy of the Ghostarchive WARC, and verify.sh. Running sh verify.sh fetches every commit listed above from flutter/flutter, checks the author on each, confirms the milestone commit carries the recorded parent and tree, proves the stored object is byte-identical to the fetched one, and matches every kept file against its SHA-256. sh verify.sh --offline checks the stored files with no network at all.
