Methods

call() → T

Available on Readable<T>, provided by the JoltUtilsReadableExtension extension

The current value using callable syntax.

derived<U>(U computed(T value)) → Computed<U>

Available on Readable<T>, provided by the JoltUtilsReadableExtension extension

A computed value derived from this readable.

dispose() → void

Disposes this computed value and removes it from future propagation.

override

get() → T

Available on Readable<T>, provided by the JoltUtilsReadableExtension extension

The current value using method syntax.

listen(void onData(T event)?, {Function? onError, void onDone()?, bool? cancelOnError, bool immediately = false}) → StreamSubscription<T>

Available on Readable<T>, provided by the JoltUtilsStreamExtension extension

Subscribes to later visible changes to this readable.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notify() → void

Notifies dependents that this computed value should be treated as changed.

override

notifySoft() → void

Recomputes this value and only notifies subscribers when the result changed.

override

readonly() → Readonly<T>

Available on Computed<T>, provided by the JoltComputedReadonlyExtension extension

Returns a cached read-only view of this computed value.

toString() → String

A string representation of this object.

override

until(bool predicate(T value), {bool? detach}) → Until<T>

Available on Readable<T>, provided by the JoltUtilsUntilExtension extension

Waits until the value satisfies a condition.

untilChanged({bool? detach}) → Until<T>

Available on Readable<T>, provided by the JoltUtilsUntilExtension extension

Waits until the value changes from its current value.

untilWhen<U>(U value, {bool? detach}) → Until<T>

Available on Readable<T>, provided by the JoltUtilsUntilExtension extension

Waits until the reactive value equals value.

Operators

operator ==(Object other) → bool

The equality operator.
