bool hasFlex(Widget widget)

Implementation

bool hasFlex(Widget widget) {
  if (widget is DataScopeWidget) {
    widget = widget.child;
  }

  // legacy widgets
  if (widget is HasController && widget.controller is WidgetController) {
    return (widget.controller as WidgetController).flex != null ||
        (widget.controller as WidgetController).flexMode != null ||
        (widget.controller as WidgetController).expanded;
  }
  // new widgets
  else if (widget is EnsembleWidget &&
      widget.controller is EnsembleWidgetController) {
    return (widget.controller as EnsembleWidgetController).flex != null ||
        (widget.controller as EnsembleWidgetController).flexMode != null;
  }
  return false;
}
