notify method

@override void notify(ReactiveNode effect)

Queues an effect for execution.

Adds the effect and any watching parent effects to the execution queue. Effects are executed together when flush is called or when a batch completes.

This batching mechanism prevents redundant computations and ensures effects run in a consistent order.

Implementation

@override
@pragma('vm:align-loops')
void notify(ReactiveNode effect) {
  LinkedEffect? head;
  final LinkedEffect tail = effect as LinkedEffect;

  do {
    (effect as LinkedEffect).nextEffect = head;
    head = effect;
    effect.flags &= -3 /*~ReactiveFlags.watching*/;

    final next = effect.subs?.sub;
    // dart format off
    if (
      next == null
      || ((effect = next).flags & ReactiveFlags.watching) == ReactiveFlags.none
    ) { // dart format on
      break;
    }
  } while (true);

  if (queuedEffectsTail == null) {
    queuedEffects = queuedEffectsTail = head;
  } else {
    queuedEffectsTail!.nextEffect = head;
    queuedEffectsTail = tail;
  }
}
