November 2025 — tamagui/tamagui: Delivered a targeted fix for the sheet closing animation visual glitch affecting sheets adapted from Dialog with snapPointsMode='fit'. By freezing the frameSize at exit, ignoring layout events during close, and locking frame height, the white flash artifacts were eliminated and transitions became smoother. The fix is associated with commit 927e2295227402190d063952e4912121e08f98b3. Impact: improved user experience through smoother sheet transitions, reduced layout thrashing during exit, and greater stability for Adapt.Contents unmount scenarios. This establishes a repeatable exit-animation pattern for Dialog-adapted sheets and demonstrates proficiency in animation state management and layout control.
