listenable property

JoltValueListenable<T> get listenable

Converts this Jolt value to a Flutter ValueListenable.

Returns a cached instance synchronized with this value. Multiple calls return the same instance.

Example:

final signal = Signal(42);
final listenable = signal.listenable;

ValueListenableBuilder<int>(
  valueListenable: listenable,
  builder: (context, value, child) => Text('$value'),
)

Implementation

JoltValueListenable<T> get listenable {
  var listenable = _listenables[this] as JoltValueListenable<T>?;

  if (listenable == null) {
    _listenables[this] = listenable = JoltValueListenable(this);
  }

  return listenable;
}
