value property

T get value

Gets the current value and registers this Rx as a dependency

Implementation

T get value {
  // Check for computed tracker first
  final computedTracker = ComputedTrackerRegistry.current;
  if (computedTracker != null) {
    computedTracker.dependencies.add(this);
    // Zero overhead: only track if DevTools is enabled
    if (SwiftDevTools.isEnabled && SwiftDevTools.isTrackingDependencies) {
      // Note: ComputedTracker doesn't have ID, skip for now
      // DevTools extension can infer from stack
    }
  }

  // Then check for mark widget
  final mark = MarkRegistry.current;
  if (mark != null) {
    mark.register(this);
    // Zero overhead: only track if DevTools is enabled
    if (SwiftDevTools.isEnabled && SwiftDevTools.isTrackingDependencies) {
      SwiftDevTools.trackDependency(
        SwiftDevTools.getMarkId(mark),
        SwiftDevTools.getRxId(this),
      );
    }
  }
  return _value;
}

@override set value (T newValue)

Sets a new value and notifies listeners if changed

Implementation

@override
set value(T newValue) {
  final oldValue = value;

  // Run middlewares
  for (final middleware in _middlewares) {
    middleware(oldValue, newValue);
  }

  super.value = newValue;

  // Run side effects
  for (final sideEffect in _sideEffects) {
    sideEffect(newValue);
  }
}
