动态列表视图生成器导航

Question

你好，我想知道如何在列表视图构建器中实现导航，这是我尝试过的。

 Widget build(BuildContext context) {
return Scaffold(
body:Container(
    padding: EdgeInsets.all(10.0),
    color: AppColors.whiteColor,
    child: Column(
      children: <Widget>[

        Flexible(
          child: AnimationLimiter(
            child: ListView.builder(
              shrinkWrap: false,
              padding: const EdgeInsets.all(8.0),
              itemCount: menuList.length,
              itemBuilder: (BuildContext context, int index) {
                return AnimationConfiguration.staggeredList(
                    position: index,
                    duration: const Duration(milliseconds: 375),
                    child: SlideAnimation(
                      verticalOffset: 44.0,
                      child: FadeInAnimation(
                        child: GestureDetector(
                          onTap: (){
                                Navigator.push(
                                  context,
                                  MaterialPageRoute(builder: (context) => menuList[index].name(menuList[index].children,widget.name,widget.code)),
                                );


                          },
                          child: Card(
                            margin: EdgeInsets.only(bottom: SizeConfig.blockSizeVertical*2),
                            child: ListTile(
                              leading: Image.network(menuList[index].icon),
                              title: Text(menuList[index].name),
                            ),
                          ),
                        ),
                      ),
                    ));
              },
            ),
          ),
        )
      ],
    ),
  ),

我对你的问题的理解是，你想根据每个索引上不同的API值打开不同的活动。为什么不在你的onTap()中加入一个IF条件来检查每个元素上的某个值，以指示导航的位置。比如说，你的onTap()中的IF条件是

if (widget.studentTestInfo.content[index].canSeeResultTr == true) {
      Navigator.push(
        context,
        MaterialPageRoute(
          builder: (context) => ResultPageLook(
            studentProfile: widget.studentProfile,
            studentTestInfo: widget.studentTestInfo,
            ), 
          )
       );
    } else {
        Navigator.push(
          context,
          MaterialPageRoute(
            builder: (context) => TestSyllabus(
              studentProfile: widget.studentProfile,
              studentTestInfo: widget.studentTestInfo,
            ),
          ),
        );
    }
