推荐答案

我认为最好的方法是使用 SingleChildScrollView:

I think the best way to do this is to use a SingleChildScrollView:

当您有一个通常会显示的框时，此小部件很有用完全可见，例如时间选择器中的钟面，但您如果容器太小，需要确保它可以滚动在一个轴上(滚动方向).

This widget is useful when you have a single box that will normally be entirely visible, for example a clock face in a time picker, but you need to make sure it can be scrolled if the container gets too small in one axis (the scroll direction).

而不是使用 ListView 只需使用 Column 并将其放在 SingleChildScrollView 内:

And instead of using a ListView just use a Column and place it inside of the SingleChildScrollView:

    SingleChildScrollView(
        child: Column(
            mainAxisSize: MainAxisSize.min,
            children: <Widget>[/**/],
        ),
    )

或者如果你出于某种原因需要使用ListView，你可以使用shr​​inkWrap和NeverScrollableScrollPhysics:

Or if you need to use ListView for some reason, you can use shrinkWrap with NeverScrollableScrollPhysics:

    SingleChildScrollView(
        child: ListView(
            shrinkWrap: true,
            physics: NeverScrollableScrollPhysics(),
            children: <Widget>[/**/],
        ),
    )
