如何在中间垂直对齐ListView [英] How to vertical align ListView in the middle

问题描述

我希望我的列表项位于 ListView

I want my list item in the middle of the ListView

@override Widget build(BuildContext context)
{
    List<String> listName = ['Woody', 'Buzz', 'Rex'];

    return Container
    (
      decoration: BoxDecoration(border: Border.all(color: Colors.pinkAccent)),
      width: 400,
      height: 700,
      alignment: Alignment.centerLeft,
      child: ListView.builder
      (
        itemCount: listName.length,
        itemBuilder: (context, index)
        {
          return OurName(listName[index]);
        },
      ),
    );
}

这是当我使用 shrinkWrap 时，当我向上滚动时，它会被切断，而无法向下滚动 shrinkWrap

This is when I use shrinkWrap, when I scroll up it's cut off and it can't be scroll down shrinkWrap

这是我所期望的期望

推荐答案

问题的关键是 ListView 的 shrinkWrap 属性.因此，要解决此问题，您可以执行以下操作:

The key to your issue is the shrinkWrap property of ListView. So to fix this you can do something like this:

Container(
        alignment: Alignment.centerLeft,
        child: ListView.builder(
          itemBuilder: (context, index) {
            return Text("The index$index");
          },
          shrinkWrap: true,
          itemCount: 30,
        ),
      ),
