The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- isDisposed → bool
-
Whether this Pod has been disposed of or not.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- updateValue → T
-
Returns the current value of the Pod and calls refresh

Methods
-
addListener(
VoidCallback listener) → void -
❌ Do not use this method directly. Use addStrongRefListener instead.
inherited
-
addSingleExecutionListener(
VoidCallback listener) → void -
Registers a listener that will be called only once when the object
notifies its listeners. After the listener is called, it is automatically
removed.
inherited
-
addStrongRefListener(
{required VoidCallback strongRefListener}) → void -
Register a closure to be called when the object notifies its listeners.

GenericPod to a new ChildPod using the specifiedreducer
.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited

reduce<
C extends Object, O extends Object> (GenericPod< O> other, TReducerFn2<C, T, O> reducer) → ChildPod<Object, C> -
Reduces the current Pod and
other
into a single ChildPod.inherited -
refresh(
) → void - Triggers notifyListeners after a zero-duration delay.
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
set(
T newValue, {bool notifyImmediately = true}) → void -
Sets the value of the Pod to
newValue
and calls notifyListeners if the value is different from the current value. -
toString(
) → String -
A string representation of this object.
inherited
-
update(
T updateValue(T oldValue), {bool notifyImmediately = true}) → void -
Updates the current value of the Pod via
updateValue
and calls notifyListeners if the returned value is different from the current value.
Operators
