CoderComputed<T> class
CoderComputed<T> is a reactive computed value based on one or more CoderStates.
Whenever any of the dependent states change, the compute function is re-evaluated.
If the result is different from the previous value, listeners are notified.

Constructors
-
CoderComputed({required T compute(), required List<
CoderState> dependencies}) - Creates a computed state based on given dependencies.
Properties
- compute → T Function()
-
Function that computes the derived value.
final
-
dependencies
→ List<
CoderState> -
List of dependent states that this computed value listens to.
final
- hashCode → int
-
The hash code for this object.

- hasListeners → bool
-
Whether any listeners are currently registered.

- 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
-
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).
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
toString(
) → String -
A string representation of this object.

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