Flutter - 如何制作水平滚动的ListView？

Question

I want to make a design like this

For this, I'm using ListView with scrollDirection: Axis.horizontal . But when I doing that its throwing errors like

I/flutter (10948):   creator: Column ← _PointerListener ← Listener ← _GestureSemantics ← RawGestureDetector ←

Widget element() {
    return Container(

          element(),

  }

Please help here and if you have a better approach then please tell. Thanks in advance.

You can copy paste run full code below
You can provide width to Container and use Column
code snippet

return Container(
      width: 200,
...   
Column(
        children: [
          Container(
            height: 250,
            child: ListView(
              //shrinkWrap: true,
              scrollDirection: Axis.horizontal,
              children: [
                element(),
                element(),
                element(),
              ],
            ),
          ),
          Divider(
            height: 50,
          ),
          Container(
            height: 250,
            child: ListView(

Answer 2

The problem is occurring because there's no height mentioned.

The parent widget of listview should have a height.

You can wrap listview inside a container and give container a height

Container(
 height:150,
 child: ListView(
      .......
 )
)

Answer 3

ListView class has property, scrollDirection. Set it like:

scrollDirection: Axis.horizontal
