我无法添加ontap功能。我非常想添加墨水池,但相同的结果卡不按下,我也试图在自定义小部件内打印,但相同的结果..此外,我还尝试了 Package 墨水池与材料和 Package 容器与IgnorePointer

Wrap(
                      children: [
                        Padding(
                          padding: const EdgeInsets.all(8.0),
                          child: InkWell(
                            onTap:onPressed,
                            child: Container(
                              width: 200,
                              child: Card(
                                  child: Column(
                                    children: [
                                  Padding(
                                    padding: const EdgeInsets.all(8.0),
                                    child: SizedBox(
                                      width: 200,
                                      height: MediaQuery.of(context).size.width < 600?150:250,
                                      child: ClipRRect(
                                       
                                        child: Image.memory(

                                          fit: BoxFit.cover,
                                        ),
                                      ),
                                    ),
                                  ),
                                
                                    ],
                                  ),
                                ),

                        ),
                          )
                        )],
                    ),
return Container(
  child:   detail_blog(
    title:title,
    Url: image_url,
  onPressed: (){
      print("preesed");
Navigator.push(context, MaterialPageRoute(builder: (builder)=>

你应该在Flutter的任何点击监听器中使用()=〉或(){}。虽然你可以直接使用函数回调,比如'onTap:functionCallback ',仍然建议将回调定义为'Function()functionCallback '。
