ConstraintAdaptiveLayout
The ConstraintAdaptiveLayout displays different widgets depending on the width constraints. It requires specifying a widget aboveZero for the >= 0 width constraint and a map of double->widget for various width breakpoints.
DebugContainer
DecoratedSingleChildScrollView
A scroll view that allows adding start and end decorations, which can be pinned or scroll with the content.
DefaultChipThemeData
DelegatingReactiveTextField<T>
DelegatingScaffold
DelegatingValueAccessor<ModelDataType, ViewDataType>
A generic ControlValueAccessor which receives a delegate for both viewToModel and modelToView to be used. Also, it can receive a parent to fall back to in case some of the delegates are missing. In addition, when fallbackToParentOnNull is true (the default) then the parent is used when the delegate returns null.

GapColumn

Ghost
HandshakeCompleter<T>
IgnoreHorizontalPaddingPivot
This widget is aware of its width. In its builder parameter it supplies a ChildWrapper function that can be used as any other widget (like Container(child: ...)). The widgets which are wrapped in this are ignoring the horizontal paddings that the are imposed on them after the pivot.

SizeClassLayout
A widget that adapts its layout based on predefined window size classes. It considers the width of the viewport to determine the window size class. orElse is the default widget to be displayed if no other widget is specified, and when the viewport width is larger than all the defined size class layouts.
SizedBy
SizeOverlay
SizeReporter
SizeThenFadeTransition
Currently only supports forward animation.
StepFocus
This is a workaround widget, because wrapping MenuItemButton in a Focus (to add autfocus: true) results in an unwanted side effect of not having a focus effect at all.
TabVisibilityChangeRecognizer

"This event fires with a visibilityState of hidden when a user navigates to a new page, switches tabs, closes the tab, minimizes or closes the browser, or, on mobile, switches from the browser to a different app."

mergeHandler(void a(FormControl)?, void b(FormControl)?) → void Function(FormControl)?
mergeTapOutsideHandler(void a(PointerDownEvent)?, void b(PointerDownEvent)?) → void Function(PointerDownEvent)?
noOpOnChange(Size _, Offset __) → void
parseTimeOfDay(String timeOfDayString) → TimeOfDay
rebuildWhenTextChanged(TextEditingController? controller) → void
Mark the caller HookWidget as needing a build when the controller's text changes.
requireMergeableTheme<T extends MergeableThemeExtension<T>>({required BuildContext context, required T propTheme}) → T
safeParseTimeOfDay(String timeOfDayString) → TimeOfDay?
tryCast<T>(dynamic value, {T? fallback}) → T?
typesEqual<T1, T2>() → bool
useAnimatedList({AnimatedRemovedItemBuilder? removedItemBuilder, Duration? removeDuration}) → _AnimatedListHookState
useAsyncEffect(Future<Dispose?> effect(), [List<Object?>? keys, List<Listenable>? listenableKeys]) → void
useAsyncEffectOnce(Future<Dispose?> effect()) → void
useCancelableDebounceCallback({required VoidCallback callback, Duration duration = const Duration(milliseconds: 300), List<Object?> keys = const <Object>[]}) → CancelableDebouncedVoidCallback
Returns a CancelableDebouncedVoidCallback which is essentially a debounced VoidCallback with the additional benefit of having a cancel method.
useCancelableThrottleCallback({required VoidCallback callback, Duration duration = const Duration(milliseconds: 300), List<Object?> keys = const <Object>[]}) → CancelableThrottledVoidCallback
Returns a CancelableThrottledVoidCallback which is essentially a throttled VoidCallback with the additional benefit of having a cancel method.
useChainedAnimationController(Animation parent, {Duration? duration, Duration? reverseDuration, String? debugLabel, double initialValue = 0, double lowerBound = 0, double upperBound = 1, TickerProvider? vsync, AnimationBehavior animationBehavior = AnimationBehavior.normal, List<Object?>? keys}) → AnimationController
useChangeNotifierSelect<T extends ChangeNotifier, R>(T notifier, {required R select(T)}) → R
Listens to a ChangeNotifier and selects and returns a value from it. When that value differs from the previous build's value then it will mark the caller HookWidget as needing a build.
useCleanup(Dispose cleanup, [List<Object?> keys = const <Object>[]]) → void
useCleanupOnce(Dispose cleanup) → void
useDebounceCallback({required VoidCallback callback, Duration duration = const Duration(milliseconds: 300), List<Object?> keys = const <Object>[]}) → VoidCallback
Returns a VoidCallback which debounces the callback by duration. Many subsequent calls to the returned VoidCallback will only result in an actual callback invocation once the duration has passed since the last call.
useDelayedExecution(VoidCallback callback, {required Duration delay}) → void
Executes a callback function after a specified delay.
useEffectiveKeys({required List<Object?>? keys, required List<Listenable>? listenableKeys}) → List<Object?>?
useEffectOnce(DisposableEffect effect) → void
Syntax sugar for omitting the keys array.

Taken from https://github.com/wasabeef/flutter_use/blob/main/packages/basic/lib/src/use_interval.dart
useListenableKeys(List<Listenable>? listenableKeys) → int
Ensure that this is not called with different number of keys across builds.
useMemoized2<R>(R valueBuilder(), [List<Object?>? keys, List<Listenable>? listenableKeys]) → R
Similar to useMemoized but it also receives an additional array of Listenable objects. When any of the supplied listenable notifies then it will mark the caller HookWidget as needing a build.
useMemoizedMinutely<R>(R valueBuilder(), [List<Object?> keys = const []]) → R
Essentially a useMemoized but it additionally is rebuilding at every minute change.
useOnChangeNotifierNotified<T extends Listenable>(T? notifier, VoidCallback onChanged, [List<Object?>? keys, List<Listenable>? listenableKeys]) → void
Listens to a ChangeNotifier and calls onChange when it notifies. It is not needed to define the notifier itself as part of the keys.
useOnChangeNotifierValueChanged<T extends Listenable, R>(T notifier, {required R select(T notifier), required dynamic onChanged(R value), List<Object?>? keys, List<Listenable>? listenableKeys}) → void
Listens to a ChangeNotifier and selects a value from it. When that value differs from the previous build's selected value then onChanged is called.
usePlainAsyncEffect(Future<void> effect(), [List<Object?>? keys, List<Listenable>? listenableKeys]) → void
usePlainAsyncEffectOnce(Future<void> effect()) → void
usePlainEffect(PlainEffect effect, [List<Object?>? keys, List<Listenable>? listenableKeys]) → void
Syntax sugar for having an effect which returns null
usePlainEffectOnce(PlainEffect effect) → void
Syntax sugar for omitting the keys array and allowing call site to pass the effect as expression body.
usePlainPostFrameEffect(PlainEffect effect, [List<Object?>? keys, List<Listenable>? listenableKeys]) → void
usePlainPostFrameEffectOnce(PlainEffect effect) → void
usePostFrameCleanup(Dispose cleanup) → void
usePostFrameEffect(DisposableEffect effect, [List<Object?>? keys, List<Listenable>? listenableKeys]) → void
usePostFrameEffectOnce(Dispose effect()) → void
useRebuild() → VoidCallback
useScrollNotificationObserver(BuildContext context, {required void handler(ScrollNotification), Dispose? dispose, List<Object?>? keys}) → void
useSelectChangeNotifier<T extends Listenable, R>(T notifier, {required R select(T notifier)}) → ChangeNotifier
Returns a ChangeNotifier which will only notify when the selected value differs from it's previous value.
useThrottleCallback({required VoidCallback callback, Duration duration = const Duration(milliseconds: 300), List<Object?> keys = const <Object>[]}) → VoidCallback
Returns a VoidCallback which throttles the callback by duration. Many subsequent calls to the returned VoidCallback will only result in an actual callback invocation once the duration has passed since the last call.
useValueListener<T>(T value, void listener(), {bool fireImmediately = true}) → void
Calls listener when value changes. If fireImmediately is true (the default), listener is called immediately.
