Flutter statecontroller.update(MaterialState.disabled,false)无效

因为中间会调用

 void initStatesController() {
    if (widget.statesController == null) {
      internalStatesController = MaterialStatesController();
    }
    statesController.update(MaterialState.disabled, !widget.enabled);
    statesController.addListener(handleStatesControllerChange);
  }

　　也就是说，传的值其实被覆盖了
