RxnDouble([double? initial])

Properties

firstRebuild ↔ bool: getter/setter pairinherited
hashCode → int: The hash code for this object.
no setterinherited
isDisposed → bool: no setterinherited
listenersLength → int: no setterinherited

no setterinherited
sentToStream ↔ bool: getter/setter pairinherited
sign → double: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the sign of the double's numerical value.
no setter
sign → double?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the sign of the double's numerical value.
no setter
stream → Stream<double?>: no setterinherited
string → String: Same as toString() but using a getter.
no setterinherited
subject → StreamController<double?>: no setterinherited
value ↔ double?: The current value of the object. When the value changes, the callbacks registered with addListener will be invoked.
getter/setter pairinherited

Methods

abs() → double: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the absolute value of this double.
abs() → double?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the absolute value of this double.
addError(Object error, [StackTrace? stackTrace]) → void: inherited
addListener(StateUpdateCallback listener) → Disposer: Register a closure to be called when the object notifies its listeners.
inherited
bindStream(Stream<double?> stream) → void: Binds an existing Stream<T> to this Rx
inherited
call([double? v]) → double?: Makes this Rx looks like a function so you can update a new value using rx(someOtherValue). Practical to assign the Rx directly to some Widget that has a signature ::onChange( value )
inherited
ceil() → int?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the least integer no smaller than this.
ceil() → int: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the least integer no smaller than this.
ceilToDouble() → double?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the least integer double value no smaller than this.
ceilToDouble() → double: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the least integer double value no smaller than this.
close() → void: Close the Rx Variable
inherited
containsListener(StateUpdateCallback listener) → bool: inherited
dispose() → void: inherited
floor() → int: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the greatest integer no greater than this.
floor() → int?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the greatest integer no greater than this.
floorToDouble() → double: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the greatest integer double value no greater than this.
floorToDouble() → double?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the greatest integer double value no greater than this.
listen(ValueChanged<double?>? onData, {Function? onError, VoidCallback? onDone, bool? cancelOnError}) → StreamSubscription<double?>: Calls callback with current value, when the value changes.
inherited
listenAndPump(void onData(double? event), {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<double?>: Returns a StreamSubscription similar to listen, but with the added benefit that it primes the stream with the current value, rather than waiting for the next value. This should not be called in onInit or anywhere else during the build process.
inherited
map<R>(R mapper(double? data)) → Stream<R>: inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
refresh() → void: inherited
removeListener(StateUpdateCallback listener) → void: Remove a previously registered closure from the list of closures that the object notifies.
inherited
reportAdd(StateUpdateCallback disposer) → void: inherited
reportRead() → void: inherited
round() → int: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the integer closest to this.
round() → int?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the integer closest to this.
roundToDouble() → double: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the integer double value closest to this.
roundToDouble() → double?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the integer double value closest to this.
toString() → String: A string representation of this object.
inherited
trigger(double? v) → void: Following certain practices on Rx data, we might want to react to certain listeners when a value has been provided, even if the value is the same. At the moment, we ignore part of the process if we .call(value) with the same value since it holds the value and there's no real need triggering the entire process for the same value inside, but there are other situations where we might be interested in triggering this.
inherited
truncate() → int: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the integer obtained by discarding any fractional digits from this.
truncate() → int?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the integer obtained by discarding any fractional digits from this.
truncateToDouble() → double?: Available on Rx<double?>, provided by the RxnDoubleExt extension
Returns the integer double value obtained by discarding any fractional digits from this.
truncateToDouble() → double: Available on Rx<double>, provided by the RxDoubleExt extension
Returns the integer double value obtained by discarding any fractional digits from this.
update(double? fn(double? val)) → void: Uses a callback to update value internally, similar to refresh, but provides the current value as the argument. Makes sense for custom Rx types (like Models).
