Flutter 3.44

Release Date: May 21, 2026

Flutter 3.44 lands with Swift Package Manager support, Impeller stability improvements, native desktop tooltips, iOS motion APIs, and DevTools profiling enhancements.

Swift Package Manager support — iOS and macOS targets consume Swift packages directly; the Flutter toolchain resolves SPM declarations during build, removing the need to wrap native libraries in CocoaPod-compatible spec files
Impeller stability on Android — frame-pacing and shader compilation fixes; first-frame render times drop roughly 18% on mid-range devices, jank in complex layouts is noticeably reduced
Native tooltip windows on desktop — tooltips are now native windows on Windows, macOS, and Linux, respecting the operating system animation curve and positioning logic
iOS motion accessibility APIs — expose iOS reduced-motion, crossfade-transition, and increased-contrast settings without platform-channel plumbing
DevTools profiling timeline — new single-timeline view visualising frame rendering, garbage collection, and widget build phases for diagnosing dropped frames
