attachToJoltAttachments static method

Disposer attachToJoltAttachments(Object target, Disposer disposer)

Attaches a disposer to a Jolt object for automatic cleanup.

Parameters:

• target: The object to attach the disposer to
• disposer: The cleanup function to execute when the object is disposed

Returns: A function that can be called to remove the disposer before disposal

The disposer will be automatically executed when the target object is garbage collected or when disposeObject is called.

Example:

final signal = Signal(0);
final cancel = JFinalizer.attachToJoltAttachments(
  signal,
  () => subscription.cancel(),
);
// Later, if needed:
cancel(); // Manually remove the disposer

Implementation

static Disposer attachToJoltAttachments(Object target, Disposer disposer) {
  assert(
      (target is JReadonlyValue || target is JEffect)
          ? !((target as dynamic).isDisposed)
          : true,
      'Jolt value is disposed');

  Set<Disposer>? disposers = joltAttachments[target];
  if (disposers == null) {
    joltAttachments[target] = disposers = {};
    joltFinalizer.attach(target, disposers);
  }

  disposers.add(disposer);
  return () {
    disposers!.remove(disposer);
  };
}
