refresh method

void refresh()

Triggers a notification without changing the value.

This also triggers middleware hooks to ensure mutations are tracked.

Implementation

void refresh() {
  // Fast Path
  if (LevitReactiveMiddleware.bypassMiddleware ||
      !LevitReactiveMiddleware.hasSetMiddlewares) {
    _controller?.add(_value);
    super.notify();
    return;
  }

  // Slow Path
  final change = LevitReactiveChange<T>(
    timestamp: DateTime.now(),
    valueType: T,
    oldValue: _value,
    newValue: _value,
    stackTrace:
        _LevitReactiveCore.captureStackTrace ? StackTrace.current : null,
    restore: (v) {
      _value = v;
      _controller?.add(_value);
      super.notify();
    },
  );

  void performRefresh(T v) {
    _controller?.add(
        v); // Uses v in case middleware modified it (unlikely for refresh but consistent)
    super.notify();
    if (_LevitReactiveCore.isBatching) {
      _LevitReactiveCore._recordBatchEntry(this, change);
    }
  }

  final wrapped =
      LevitStateMiddlewareChain.applyOnSet<T>(performRefresh, this, change);
  wrapped(_value);
}
