Flutter 3.44.9

Google's Flutter team shipped Flutter 3.44.9 on August 6, 2026, a stable hotfix release aimed squarely at a frustrating iOS debugging hang. The update is a targeted patch on top of 3.44.8, addressing a bug that stalled the Flutter CLI and test runners when a debugged iOS app crashed.

What Changed

The headline fix is flutter/186366: when debugging an iOS app, a crash in the app would leave the Flutter CLI and associated tests hanging indefinitely. The toolchain now detaches LLDB and prints a stack trace on process stop, so a crash surfaces as actionable output instead of a frozen terminal.

Under the Hood

• Android SDK cleanup — Removed an ancient tools dependency from the android_sdk bundle that served no purpose in modern builds
• Engine sync — engine.version synced to 5a2a6a42cce67f965cf540fcecf616faca624aa1 for the 3.44.9 candidate
• Dart SDK — ships with Dart 3.12.2, matching the 3.44 line

Why It Matters

Hotfix releases like this one rarely make headlines, but the iOS crash hang was the kind of bug that eats an afternoon — silent, intermittent, and only reproducible mid-debug-session. For teams running widget tests against iOS simulators, upgrading to 3.44.9 removes a known point of failure before it becomes a production incident.

What's Next

Flutter 3.47 remains on the August 2026 release track, with the branch cutoff already passed on July 7. Meanwhile, 3.44.9 is available now via the stable channel and flutter upgrade. As the team puts it in the release notes: if you hit the iOS crash hang, this is the release you've been waiting for.
