Functions

computed<T>(T getter()) → Computed<T>: Creates a readonly computed value.
customRef<T>(CustomRefFactory<T> factory) → Ref<T>: Creates a customized ref with explicit control over dependency tracking.
effectScope({bool detached = false}) → EffectScope: Creates an effect scope for grouping reactive effects.
get<T extends Object>({Symbol? key}) → T: Get a registered instance or factory result.
getCurrentScope() → EffectScope?: Get the currently active effect scope.
isMarkedRaw(Object? value) → bool: Check if an object is marked as raw.
isProxy(Object? value) → bool: Check if a value is a reactive proxy (Ref, Computed, Readonly, ShallowRef).
isReactive(Object? value) → bool: Check if a value is reactive (Ref, Computed, or ShallowRef).
isReadonly(Object? value) → bool: Check if a value is readonly (Readonly or read-only Computed).
isRef(Object? value) → bool: Check if a value is a Ref.
isRegistered<T extends Object>({Symbol? key}) → bool: Check if a type (and optional key) is registered.
markRaw<T extends Object>(T value) → T: Marks an object so that it will never be converted to a reactive proxy.
onScopeDispose(void callback(), {bool failSilently = false}) → void: Register a dispose callback on the current active effect scope.
onWatcherCleanup(CleanupFn cleanup, {bool failSilently = false}) → void: Register a cleanup function for the current watcher.
readonly<T>(Object source) → Readonly<T>: Creates a readonly proxy of a reactive value.
ref<T>(T value) → Ref<T>: Creates a reactive reference to a value.
register<T extends Object>(T instance, {Symbol? key}) → void: Register a singleton instance.
registerFactory<T extends Object>(T factory(), {Symbol? key}) → void: Register a factory function.
resetLocator() → void: Reset all registrations.
shallowReadonly<T>(Object source) → ShallowReadonly<T>: Creates a shallow readonly wrapper.
shallowRef<T>(T value) → ShallowRef<T>: Creates a shallow ref - only .value access is reactive.
toRaw<T>(Object? value) → T: Returns the raw, original value from a reactive wrapper.
toRef<T>(Object source) → Ref<T>: Normalizes value/ref/getter to a Ref.
toRefs<T>(Map<String, T> source) → Map<String, Ref<T>>: Converts a Map to a Map of Refs.
toValue<T>(Object source) → T: Normalizes values/refs/getters to values.
triggerRef(ShallowRef ref) → void: Force trigger effects that depend on a shallow ref.
unref<T>(Object? maybeRef) → T: Unwrap a Ref to get its value, or return the value as-is if not a Ref.
unregister<T extends Object>({Symbol? key}) → void: Remove a registered instance or factory.
watch<T>(T source(), WatchCallback<T> callback, {WatchOptions options = WatchOptions.defaults}) → WatchHandle: Watches a reactive source and invokes a callback when it changes.
watchEffect(EffectFn effect, {WatchOptions options = WatchOptions.defaults}) → WatchHandle: Runs an effect immediately and re-runs it when dependencies change.
watchMultiple<T>(List<T Function()> sources, void callback(List<T> values, List<T?> oldValues, OnCleanup onCleanup), {WatchOptions options = WatchOptions.defaults}) → WatchHandle: Watches multiple sources and invokes callback when any of them change.
watchPostEffect(EffectFn effect) → WatchHandle: Alias for watchEffect with flush: FlushMode.post.
watchSyncEffect(EffectFn effect) → WatchHandle: Alias for watchEffect with flush: FlushMode.sync.
writableComputed<T>({required T get(), required void set(T value)}) → WritableComputed<T>: Creates a writable computed value.
