Inheritance
Implemented types
Mixed-in types
Implementers
Properties
hashCode → int
The hash code for this object.
no setter inherited
isClosed → bool
Whether the bloc is closed.
no setter inherited
set put log type
no setter override
runtimeType → Type
A representation of the runtime type of the object.
no setter inherited
state → M
The current state .
no setter inherited
stream → Stream <M >
The current stream of states.
no setter inherited
value → M
Current state value using FlowR's legacy name.
no setter inherited
Methods
addError (Object error , [StackTrace ?stackTrace → void
Reports an error which triggers onError with an optional StackTrace .
inherited
autoDispose <T extends StreamSubscription ? > (T subs , {String ?tag → T
inherited
autoDisposeNotifier <N extends ChangeNotifier ? > (N ntf , {String ?tag → N
inherited
close ()
→ Future <void >
Close the bloc and dispose FlowR helper resources.
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
debugDescribeChildren ()
→ List <DiagnosticsNode
Returns a list of DiagnosticsNode objects describing this node's
children.
override
debugFillProperties (DiagnosticPropertiesBuilder properties → void
Add additional properties associated with the node.
override
dispose ()
→ void
inherited
emit (M state → void
Updates the state to the provided state.
emit does nothing if the state being emitted
is equal to the current state.
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
logE (String message , {Object ?error , StackTrace ?stackTrace , DateTime ?time , int ?sequenceNumber , String ?name , Zone ?zone → void
for 'error'
inherited
logF (String message , {Object ?error , StackTrace ?stackTrace , DateTime ?time , int ?sequenceNumber , String ?name , Zone ?zone → void
inherited
logger (String message , {DateTime ?time , int ?sequenceNumber , int level = 800 , String ?name , Zone ?zone , Object ?error , StackTrace ?stackTrace , bool uriFrame = true → dynamic
logExtra print stack frame info
name logger.name
null: will use 'runtimeType'
stackTrace will print with red color by dev.log
but if error == null: will ignore stackTrace
inherited
logI (String message , {Object ?error , StackTrace ?stackTrace , DateTime ?time , int ?sequenceNumber , String ?name , Zone ?zone → void
inherited
logS (String message , {Object ?error , StackTrace ?stackTrace , DateTime ?time , int ?sequenceNumber , String ?name , Zone ?zone → void
for debug 'shout'
inherited
logW (String message , {Object ?error , StackTrace ?stackTrace , DateTime ?time , int ?sequenceNumber , String ?name , Zone ?zone → void
for 'warning'
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
ntfBy <T extends ChangeNotifier > (String tag → T
inherited
onChange (Change<M > change → void
Called whenever a change occurs with the given change.
A change occurs when a new state is emitted.
onChange is called before the state of the cubit is updated.
onChange is a great spot to add logging/analytics for a specific cubit.
inherited
onError (Object error , StackTrace stackTrace → void
Called whenever an error occurs and notifies BlocObserver.onError.
inherited
put (M value → M
Put value to this cubit.
inherited
putError (Object error , [StackTrace ?stackTrace → void
Put error value to this cubit.
inherited
putWithLogging (M value , {OnLogging <M > ?logging → M
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? >
run and catch error, then putError
inherited
skpIf (bool condition , String reason , {Level level = Level.FINE → 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 , {Level level = Level.FINE → 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
toDiagnosticsNode ({String ?name , DiagnosticsTreeStyle ?style → DiagnosticsNode
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep .
override
toString ({DiagnosticLevel minLevel = DiagnosticLevel.info → String
A string representation of this object.
inherited
toStringDeep ({String prefixLineOne = '' , String ?prefixOtherLines , DiagnosticLevel minLevel = DiagnosticLevel.debug , int wrapWidth = 65 → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow ({String joiner = ', ' , DiagnosticLevel minLevel = DiagnosticLevel.debug → String
Returns a one-line detailed description of the object.
inherited
toStringShort ()
→ String
A brief description of this object, usually just the runtimeType and the
hashCode .
inherited
