Flutter 3.47.1

Flutter 3.47.1 is a hotfix release on the stable 3.47 branch, tagged by the Flutter team on August 19, 2026. It is a tightly-scoped patch that rolls a synchronized engine build into the 3.47 candidate channel rather than introducing fresh framework features.

What's In This Patch

The release syncs the engine version to commit 5d53178, bringing stability corrections to the Dart and engine layers that sit beneath the 3.47 framework. For teams already on Flutter 3.47.0, this is a drop-in update that keeps the framework in lockstep with the matching engine without API changes.

Upgrade Path

Because 3.47.1 is a point release, the upgrade is straightforward for anyone on the 3.47 series. Run flutter upgrade to pull the new build, or pin to the specific version in CI for reproducible releases. As always, run your test suite after updating before shipping to production.

The next milestone, 3.48, is already moving through its pre-release channel — so 3.47.1 represents a maintenance checkpoint while the team focuses on the upcoming feature release.
