RxnDouble class - rx_types library

Constructors

RxnDouble([double? initial])

Properties

canUpdate → bool: no setterinherited
firstRebuild ↔ bool: getter/setter pairinherited
hashCode → int: The hash code for this object.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sentToStream ↔ bool: getter/setter pairinherited
stream → Stream<double?>: no setterinherited
string → String: Same as toString() but using a getter.
no setterinherited
subject ↔ GetStream<double?>: getter/setter pairinherited
value ↔ double?: Returns the current value
getter/setter pairinherited

Methods

addError(Object error, [StackTrace? stackTrace]) → void: inherited
addListener(GetStream<double?> rxGetx) → void: This is an internal method. Subscribe to changes on the inner stream.
inherited
bindStream(Stream<double?> stream) → void: Binds an existing Stream<T> to this Rx
inherited
call([double? v]) → double?: updates the value to null and adds it to the Stream. Even with null-safety coming, is still an important feature to support, as call() doesn't accept null values. For instance, InputDecoration.errorText has to be null to not show the "error state".
inherited
close() → void: Closes the subscriptions for this Rx, releasing the resources.
inherited
listen(void onData(double?), {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<double?>: 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: Makes a direct update of value adding it to the Stream useful when you make use of Rx for custom Types to referesh your UI.
inherited
toJson() → dynamic: Returns the json representation of value.
inherited
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
update(void 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).

Operators

operator ==(Object o) → bool: This equality override works for _RxImpl instances and the internal values.
