Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

autoDispose<T extends StreamSubscription?>(T subs, {String? tag}) → T

inherited

debounce<R>(Object tag, Duration duration, FutureOr<R> action(), {Duration? maxDuration}) → FutureOr<R?>

debounce 防抖: 停止操作后等待 duration 执行最后一次。 maxDuration: 可选，解决“无限重置”问题。如果持续触发超过此时间，强制执行一次。

inherited

dispose() → void

inherited

frPrint(String message, {DateTime? time, int? sequenceNumber, int? level, String? name, Zone? zone, Object? error, StackTrace? stackTrace}) → dynamic

inherited

isDebounceLocked(Object tag) → bool

检查是否正在防抖等待中

inherited

isMutexLocked(Object tag) → bool

检查是否正在执行 mutex 任务

inherited

isThrottleLocked(Object tag) → bool

检查是否处于节流冷却期

inherited

logger(String message, {LogExtra? logExtra, DateTime? time, int? sequenceNumber, int level = 0, String? name, Zone? zone, Object? error, StackTrace? stackTrace, bool uriFrame = true}) → dynamic

logExtra print stack frame info name logger.name null: and if logExtra ==null: will use 'runtimeType' else: will use stack frame info stackTrace will print with red color by dev.log but if error == null: will ignore stackTrace

inherited

mutex<R>(Object tag, FutureOr<R> action()) → FutureOr<R?>

mutex 互斥锁 (Exhaust): 立即执行，执行期间的触发直接丢弃。

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

runCatching<R>(FutureOr<R?> block(), {FutureOr<R?> onSuccess(R data)?, FutureOr<R?> onFailure(Object e, StackTrace s)?, bool ignoreSkipError = true, int slowlyMs = 0, Object? debounceTag, Object? throttleTag, Object? mutexTag}) → FutureOr<R?>

ignoreSkipError same as update((o)=>null) true: SkipError will not trigger onFailure when true ref skpIf/skpNull slowlyMs if set <=0 value, will ignore debounce/throttleTag debounceTag enable debounce throttleTag enable throttle mutexTag enable concurrency lock (Exhaustive behavior)

inherited

skpIf(bool condition, String reason) → void

if you want interrupt the normal flow, but not trigger runCatching.onFailure

inherited

skpIfNull(Object? obj, String reason) → void

if obj ==null, throw SkipError ref skpIf

inherited

skpNull<T>(T? obj, String reason) → T

if obj == null: throw SkipError else: return obj!

inherited

subBy<T extends StreamSubscription>(String tag) → T

inherited

throttle<R>(Object tag, Duration duration, FutureOr<R> action(), {bool ensureLast = false}) → FutureOr<R?>

throttle 节流: 固定频率执行。 配合 mutex 解决异步任务重叠问题：如果周期到了但上次任务还没跑完，直接跳过。 ensureLast: 如果为 true，则在节流期间的最后一次触发将被防抖补发。

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
