launchWithCreated / launchWithStateAtLeast - run a coroutine once a lifecycle state is reached
SavedStateHandle.field() - property delegate for ViewModel saved state (natively supported types; use AndroidX saved() for @Serializable
types)
SavedStateHandle.stateField() - like field(), but exposes a MutableStateFlow for observable saved state
Platform.name, platformContext - platform info and the shared application context (JVM: id detected from kaiteki.applicationId, jpackage
launcher, main class or jar name; override via PlatformContext.initialize(applicationId))
platformContext.dataDirectory / cacheDirectory - okio Paths to the app's persistent and cache directories, resolved per OS on the JVM
Initializer - marker interface for DI-driven startup logic
DataStore extensions for DataStore<Preferences>: get / set operators, flow, remove
Modifier.pressAndHold() - repeats a click while pressed, accelerating over time
Modifier.keepScreenOn() - keeps the screen awake (Android flag / iOS idleTimerDisabled)
Modifier.cacheSize() - reuses a previously measured size, e.g. for moveable content
Modifier.blurHash() - draws a BlurHash placeholder behind the content
Expressive Material 3 buttons in five sizes: ButtonExtraSmall to ButtonExtraLarge, likewise for Outlined, Elevated, FilledTonal and Text
buttons, with optional start/end icons
Icon buttons in the same sizes: IconButton*, FilledIconButton*, FilledTonalIconButton*, OutlinedIconButton* and the matching
*IconToggleButton* variants
SegmentedListItemColumn - column of SegmentedListItems and Cards shaped for their position in the group
ExpressivePullToRefreshBox - pull-to-refresh with the Expressive loading indicator
ResideLayout + rememberResideLayoutState() - side-menu layout where the content pane slides aside with a 3D scale/tilt effect to reveal a menu
VerticalScrollbar / HorizontalScrollbar - lightweight scrollbar thumbs for a ScrollState
BracketsOverlay / BracketsShape - rounded corner brackets like a QR or document scanner frame
StyledSnackbarHost + SnackbarController - send SnackbarEvents from anywhere, e.g. a ViewModel, rendered with custom shape, colors and layout
rememberCustomTabsUriHandler() - open links in-app (Chrome Custom Tabs on Android, SFSafariViewController on iOS)
KaitekiIcon - the Kaiteki logo as an ImageVector
PagerHolder - wrapper around Pager with refresh, retry, cachedIn, and reactive parameter support
Ready-made PagingSource implementations based on Arrow Either error handling and duplicate detection
(configurable DuplicateStrategy: invalidate on shifted data, or filter duplicates from non-deterministic backends):
SinglePagePagingSource - non-paginated single-page data
pagingDataOf(), emptyPagingSource(), emptyItemSnapshotList() - static data for previews and tests
CameraView - Compose camera preview (Android: CameraX, iOS: AVFoundation)
rememberCameraController() - zoom, torch, focus control
CameraController.bindBarcodeAnalyzerFlow(formats) - real-time barcode scanning with configurable formats
CameraController.bindTextAnalyzerFlow(minConfidence) - live text recognition (OCR)
Flow<OCRResult>.stabilized() - suppresses OCR flicker by merging results across frames
AnalysisRegion - restricts barcode/OCR results to the part of the frame visible in the viewfinder, via
CameraView(analysisRegion = AnalysisRegion.VisibleArea(inset)); default FullFrame
BarcodeResult - includes the normalized bounding box of the detected code (relativeX/Y/Width/Height)
CameraController.analysisRegionRect - the active analysis region in viewfinder coordinates, e.g. for drawing scan brackets
Multiplatform API with platform-specific implementations (Android + iOS)
Denied(shouldShowRationale)
PermissionState.launchPermissionRequest() / openSystemPreferences() - request the permission or deep-link to app settings
