Flutter News June 2026 (2/2)

1. Flutter 3.44.3 and 3.44.4 — Two Stable Hotfixes

The second half of June was all about maintenance releases following May's 3.44 from Google I/O. Flutter 3.44.3 landed on June 22, fixing several notable crashes: an Android crash when a texture was destroyed before its GLES fence was used; macOS/iOS crashes caused by concurrent directory, file, and symlink creation during Swift Package Manager builds; and broken rendering of animated PNGs. It also quiets asset-related build messages (demoted from warning to trace) for a cleaner build log.

Three days later, on June 25, Flutter 3.44.4 followed with a bounds-checking fix in FlAccessibleTextField on Flutter Linux — an accessibility correction. Upgrade via flutter upgrade, especially if you're using SwiftPM on iOS/macOS or rendering animated PNGs.

2. DCM 1.38.0 — 14 New Rules with a Security Focus

The code-quality tool DCM shipped 1.38.0 on June 22, packed with additions. It introduces 14 new rules, several of them security-focused — for example catching WebView vulnerabilities and restricting unsafe JavaScript. You can now disable auto-fixes for a specific rule, the Console reporter gained a compact single-line-per-violation output format, and the global version constraint can be configured via the DCM Teams Console.

Also notable: support for converting fields to private named parameters via dcm fix --type=unnecessarily-public-code (Dart 3.12+ only, which introduced private named parameters). The dashboard now remembers selected intervals and groups after a reload and lets you hide selected categories in charts.
