Properties

logExtra → LogExtra?
set put log type
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
autoDispose<T extends StreamSubscription?>(T subs, {String? tag}) → T
inherited
autoDisposeNotifier<N extends ChangeNotifier?>(N ntf, {String? tag}) → N
inherited
debounceMs<R>(Object tag, R func, {int ms = 200}) → Future<R?>
inherited
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
frPrint(String message, {DateTime? time, int? sequenceNumber, int? level, String? name, Zone? zone, Object? error, StackTrace? stackTrace}) → dynamic
inherited
listen(void onChange(T ntf)?, {bool where(T ntf)?}) → T

Available on T, provided by the ChangeNotifierX extension

where filter the notification,
logger(String message, {LogExtra? logExtra = !kReleaseMode ? LogExtra.self : null, bool uriFrame = false, DateTime? time, int? sequenceNumber, int level = 0, String? name, Zone? zone, Object? error, StackTrace? stackTrace}) → 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
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners([FutureOr<M> update(M old)?]) → void
when invoke FrChangeNotifierMx.notifyListeners must invoke update (put)
inherited
ntfBy<T extends ChangeNotifier>(String tag) → T
inherited
put(M value) → M
when invoke update (put) will call ChangeNotifier.notifyListeners
inherited
putError(Object error, [StackTrace? stackTrace]) → void
put error value to _subject
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
runCatching<R>(FutureOr<R?> block(), {FutureOr<R?> onSuccess(R data)?, FutureOr<R?> onFailure(Object e, StackTrace s)?, dynamic ignoreSkipError = true}) → FutureOr<R?>
run and catch error, then putError
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
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
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
update(FutureOr<M> update(M old), {dynamic onError(Object e, StackTrace s)?, int slowlyMs = 100, Object? debounceTag, Object? throttleTag, dynamic ignoreSkipError = true}) → FutureOr<M?>
update if return value, will call put if return null, will not call put/putError onError if set null，will call putError if set function value, will not call putError, you can invoke putError manually slowlyMs if set <=0 value, will ignore debounce/throttleTag debounceTag enable debounce, require unique within the VM scope throttleTag enable throttle， require unique within the VM scope ignoreSkipError ref runCatching.ignoreSkipError
inherited
updateRaw(FutureOr<M> up(M old), {dynamic onError(Object e, StackTrace s)?, int slowlyMs = 100, Object? debounceTag, Object? throttleTag, dynamic ignoreSkipError = true}) → FutureOr<M?>
Deprecated use 'update'
inherited

Operators

operator ==(Object other) → bool
The equality operator.
