  if (!isSameType) {
    var parentLookup = Data.maybeFind<FormFieldHandle>(context);
    assert(parentLookup != this, 'FormEntry cannot be its own parent');
    return parentLookup?.reportNewFormValue<T>(value);
  }
  var cachedValue = _cachedValue;
  if (cachedValue != null && cachedValue.value == value) {
    return _validity.value;
  }
  _cachedValue = _FormEntryCachedValue(value);
  return _controller?.attach(context, this, value, widget.validator);
