我正在尝试预加载我的图像并在初始化状态下声明一次

范例：

late List<String> _assetBg;
  late List<Image> _imagesBg;

  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    _assetBg = ['assets/images/1.jpg',
      'assets/images/2.jpg',
      'assets/images/3.jpg',
      'assets/images/4.jpg'];

    _imagesBg = _initializeListImage(context, _assetBg);
          
    WidgetsBinding.instance!.addPostFrameCallback((timeStamp) {
      _tombolRenderBox =
          _tombolKey.currentContext!.findRenderObject() as RenderBox;
    });
  }

问题是：

List<Image> _initializeListImage (BuildContext context,List<String> assets){
    List<Image> result = [];
    for (var asset in assets) {
      result.add(
          Image(
            image: AssetImage(asset),
            ///Problem is here :
            height: MediaQuery.of(context).size.height,
            width: MediaQuery.of(context).size.width * 2,
            fit: BoxFit.cover,

          )
      );
    }
    return result;
  }

并在此处预加载：

@override
  void didChangeDependencies() {
    super.didChangeDependencies();
    _prechaceImage(context, _imagesBg);
  }

void _prechaceImage(BuildContext context, List<Image> images){
    for(var image in images){
      precacheImage(image.image, context);
    }
  }

但这给了我一个错误

错误：

dependOnInheritedWidgetOfExactType<MediaQuery>() or dependOnInheritedElement() was called before _IntroScreenState.initState() completed.
有办法解决这个问题吗？我真的需要计算屏幕宽度来动画旋转我的小部件，谢谢帮助。
