Native module:
- Add `fullHeight` prop to BottomSheetView on Android and iOS
- iOS: fullHeight sets detent to .large, skips content observation
- Android: fullHeight uses isFitToContents=false with expandedOffset=statusBarHeight
Android bottom sheet behavior overhaul:
- Switch normal sheets to isFitToContents=false with expandedOffset, enabling
proper 3-state snapping (half-expanded ↔ expanded ↔ hidden). Previously
isFitToContents=true prevented settling at half-expanded during gestures,
making it impossible to swipe back down from expanded.
- preventExpansion sheets keep isFitToContents=true with maxHeight cap, plus
a state callback safety net that bounces EXPANDED→HALF_EXPANDED. This
catches an edge case where rapid content resizes during opening can invert
the expanded/half-expanded offsets, causing the sheet to dismiss.
- Add requestLayout() after maxHeight changes in updateLayout() so the
FrameLayout actually re-measures (fixes keyboard padding not resizing sheet)
- Set backgroundTint=transparent in the theme to remove Material3 surface
tint that was visible in gaps between sheet and screen edge
Keyboard handling:
- Remove native keyboard expansion logic (insets listener, isKeyboardVisible
tracking, manual STATE_EXPANDED on keyboard show)
- Replace with JS-side keyboard padding: ScrollableInner listens for RN
Keyboard events and adds bottom padding equal to keyboard height
- Generalize useOnKeyboardDidShow → useOnKeyboard(eventName, cb)
Callers:
- Replace minHeight: screenHeight hack with fullHeight: true in EditProfile,
ChangeHandle, AddAppPassword, ImageAltText, GifAltText, LanguageSelect,
FollowDialog, GifSelect, StarterPack, Select, NewChat, ShareViaChat,
DraftsList, WizardEditList, ListAddRemoveUsers, CreateOrEditList
- Remove unused useWindowDimensions imports
- ServerInput: simplify to just preventExpansion (was platform-specific)
- ImageAltTextDialog: remove old {height: 300} keyboard spacer hack
