…n Android (minDistance) A bottom Dialog/ActionSheet opened from a gesture-driven trigger (e.g. List.Item's TapGestureHandler firing onPress on END) can rest part-way open on Android: the residual touch leaks into the Dialog's own panGesture and drives `visibility` mid-open, interrupting the open spring. Adding a minDistance activation threshold to the pan prevents a near-static residual touch from engaging it, while drag-to-dismiss keeps working.

Description
On Android, a bottom-direction
Dialog(and thereforeActionSheet, which builds on it) can open only part-way — resting below its final position with just the header visible — when it is opened as a direct result of a gesture-driven trigger (e.g.List.Item, whoseTapGestureHandlerfiresonPresson gesture END while the touch is still settling). A plain touchable trigger (e.g.Button) lifts cleanly before the modal mounts and is unaffected.Root cause: the Dialog's own
panGesturehas no activation threshold, so on Android the residual touch stream from the triggering gesture leaks into the freshly-mounted pan and drivesvisibilitymid-open, interrupting thewithSpring(1)open animation. Because the translation isinterpolate(visibility, [0,1], [hiddenLocation, 0], CLAMP), an interruptedvisibility(< 1) leaves the card translated part-way down. Dismiss is unaffected (the residual touch is long gone by then), which is why the close animation always plays from the full height.Fix: add
.minDistance(10)to the DialogpanGestureso it only engages on a deliberate drag. A residual, near-static touch can no longer activate the pan and overwritevisibility, while drag-to-dismiss (movement well beyond the threshold) keeps working unchanged.Changelog
Dialog/ActionSheet: fixed the bottom sheet occasionally opening part-way on Android when triggered from a gesture-based component (e.g.
List.Item); the open animation is no longer interrupted by the triggering touch.Additional info
Under investigation for MOBAPP-2994 (Wix OneApp — "Mute Notifications" ActionSheet opening partially on Android). Draft while verifying on-device via the standard snapshot → wrapper → app build flow.
