I'm trying to construct a simple login page for my Flutter app. I've successfully built the TextFields and log in/Sign in buttons. I want to add a horizontal ListView. When I run the code my elements disappear, if I do it without the ListView, it's fine again. How can I do this correctly?

return new MaterialApp(
        home: new Scaffold(
          appBar: new AppBar(
            title: new Text("Login / Signup"),
          ),
          body: new Container(
            child: new Center(
              child: new Column(
              mainAxisAlignment: MainAxisAlignment.center,
                children: <Widget>[
                  new TextField(
                    decoration: new InputDecoration(
                      hintText: "E M A I L    A D D R E S S"
                    ),
                  ),
                  new Padding(padding: new EdgeInsets.all(15.00)),
                  new TextField(obscureText: true,
                    decoration: new InputDecoration(
                      hintText: "P A S S W O R D"
                    ),
                    ),
                  new Padding(padding: new EdgeInsets.all(15.00)),
                  new TextField(decoration: new InputDecoration(
                    hintText: "U S E R N A M E"
                  ),),
                  new RaisedButton(onPressed: null,
                  child:  new Text("SIGNUP"),),
                  new Padding(padding: new EdgeInsets.all(15.00)),
                  new RaisedButton(onPressed: null,
                  child: new Text("LOGIN"),),
                  new Padding(padding: new EdgeInsets.all(15.00)),
                  new ListView(scrollDirection: Axis.horizontal,
                  children: <Widget>[
                    new RaisedButton(onPressed: null,
                    child: new Text("Facebook"),),
                    new Padding(padding: new EdgeInsets.all(5.00)),
                    new RaisedButton(onPressed: null,
                    child: new Text("Google"),)
                  ],)

                ],
              ),
            ),
            margin: new EdgeInsets.all(15.00),
          ),
        ),
      );

I've got this problem too. My solution is use Expanded widget to expand remain space.

Column(
  children: <Widget>[
    Expanded(
      child: horizontalList,
    )
  ],
);

    This is a great solution because it allows for variable sized heights/widths of the ListView, like when you want it to just take up the remaining space. It allows you to account for varying screen sizes when it's too difficult to know the exact height/width. – Daniel Allen Jul 26 '19 at 12:26

    This should be the accepted answer. This solution allows the ListView to take the rest of the screen without having to deal with media query. – Terence Ponce Jul 31 '19 at 02:46

    I'm too new to Flutter to know why this works, but I'm glad it does. Thank you. Flutter's error messages weren't very helpful to explain the root cause of this problem for a non-expert. – devdanke Jun 21 '20 at 17:27

    Can someone explain what causes this problem and why `Expanded` fixes it? – Dallin Davis Oct 12 '21 at 19:40

Reason for error:

Column expands to the maximum size in main axis direction (vertical axis), and so does the ListView.

Solutions:

So, you need to constrain the height of the ListView. There are many ways of doing it, you can choose that best suits your need.


  1. If you want to allow ListView to take up all remaining space inside Column, use Expanded.

    Column(
      children: <Widget>[
        Expanded( //        <-- Use Expanded 
          child: ListView(...),
        )
      ],
    )
    

  1. If you want to limit your ListView to a certain height, use SizedBox.

    Column(
      children: <Widget>[
        SizedBox(
          height: 200, // Constrain height.
          child: ListView(...),
        )
      ],
    )
    

  1. If your ListView is small, you may try shrinkWrap property on it.

    Column(
      children: <Widget>[
        ListView(
          shrinkWrap: true, // Set this
        )
      ],
    )
    

  1. If you want to make ListView to as small as it can be, use Flexible with ListView.shrinkWrap:

    Column(
      children: <Widget>[
        Flexible( //        <-- Use Flexible 
          child: ListView(
            shrinkWrap: true, // and set this
          ),
        )
      ],
    )

You can check console output. It prints error:

The following assertion was thrown during performResize(): The horizontal viewport was given unbounded height. Viewports expand in the cross axis to fill their container and constrain their children to match their extent in the cross axis. In this case, a horizontal viewport was given an unlimited amount of vertical space in which to expand.

You need to add a height constraint to your horizontal list. E.g. wrap in SizedBox with height:

SizedBox(
  height: 44.0,
  child: ListView(
    scrollDirection: Axis.horizontal,
    children: <Widget>[
      RaisedButton(
        onPressed: null,
        child: Text("Facebook"),
      ),
      Padding(padding: EdgeInsets.all(5.00)),
      RaisedButton(
        onPressed: null,
        child: Text("Google"),
      )
    ],
  ),
)

Expanded Widget increases its size as much as it can with the space available Since ListView essentially has an infinite height it will cause an error.

 Column(
  children: <Widget>[
    Flexible(
      child: ListView(...),
    )
  ],
)

Here we should use the Flexible widget as it will only take the space it required as Expanded take full screen even if there are not enough widgets to render on full screen.

I have SingleChildScrollView as a parent, and one Column Widget and then List View Widget as last child.

Adding these properties in List View Worked for me.

  physics: NeverScrollableScrollPhysics(),
  shrinkWrap: true,
  scrollDirection: Axis.vertical,

    `scrollDirection: Axis.vertical` is the default, so that's not part of the solution. Also, this disables scrolling on the list. – Loolooii May 30 '21 at 17:19
  • That has to be an accepted answer! Problem with Expanded and Flexible is `flex`, which takes up all the space which you planned for a different flexible widget. `shrinkWrap` solves that while `physics` disables overflow scrolling effect. – Krin-San Nov 16 '21 at 23:14

As have been mentioned by others above,Wrap listview with Expanded is the solution.

But when you deal with nested Columns you will also need to limit your ListView to a certain height (faced this problem a lot).

If anyone have another solution please, mention in comment or add answer.

Example

  SingleChildScrollView(
   child: Column(
     children: <Widget>[
       Image(image: ),//<< any widgets added
       SizedBox(),
       Column(
         children: <Widget>[
           Text('header'),  //<< any widgets added
            Expanded(child: 
            ListView.builder(
              //here your code
               scrollDirection: Axis.horizontal,
        itemCount: items.length,
        itemBuilder: (BuildContext context, int index) {
            return Container();
                   } 
         )
        ),
        Divider(),//<< any widgets added
         ],
       ),

     ],
   ), 
  );

    in nested columns don't use expanded just use shrikWrap: true, physics: NeverScrolPhysics() properties in listView – Mohamed Kamel Aug 05 '20 at 23:22
  • Wrapping the overflowing Column Widget(Check the error message in your terminal you should see the file and line causing the error) with a SingleChildScrollView widget worked for me. – F KIng Nov 19 '20 at 15:17
  • Thanks for reply, Now You could use shrink , sizedbx or flexiable with fit as mention by @CopsOnRoad aboce – UN..D Apr 02 '22 at 09:37

Actually, when you read docs the ListView should be inside Expanded Widget so it can work.

  Widget build(BuildContext context) {
return Scaffold(
    body: Column(
  children: <Widget>[
    Align(
      child: PayableWidget(),
    ),
    Expanded(
      child: _myListView(context),
    )
  ],
));

}

You can use Flex and Flexible widgets. for example:

Flex(
direction: Axis.vertical,
children: <Widget>[
    ... other widgets ...
    Flexible(
        flex: 1,
        child: ListView.builder(
        itemCount: ...,
        itemBuilder: (context, index) {
            ...
        },
        ),
    ),
],

);

    why Flex? can you explain? I think the OP is asking how toadd ListView in a `Column` specifically. – Gel Dec 03 '20 at 16:59

[Solution Preview] - [List Items are scrollable but heading is fixed]

enter image description here

I have very small & straight forward answer, see putting listview inside column will force column to expand infinitely, which is basically an error thing.

Now if you put physics: NeverScrollableScrollPhysics(), like others suggested, in listview then whats the point of having listview if you disable scrolling inside it..

There is an easy fix, frankly I landed on this by hit and trial. Let me give you small explanation after code.

Column(
      children: [
        Text(
          "All Bookings",
          style: TextStyle(fontSize: 20, fontWeight: FontWeight.w600, color: Colors.brown[700]),
        ),
        Expanded(
          child: Container(
            margin: EdgeInsets.only(top: 24),
            child: ListView.builder(
              itemCount: 30,
              itemBuilder: (BuildContext context, int index) => ListTile(
                title: Text("List Item ${index + 1}"),
              ),
            ),
          ),
        ),
      ],
    )

I had requirement to have title inside Column as first element & then put a Listview so that user can have scrolling list. This is a generic kind of requirement. You can put this in Bottom Sheet or Modal too.

Code Explanation:

  1. I kept first child as heading inside Column ok (which i donot want to scroll away, i want it to be fixed)
  2. I have Expanded child inside column, which is like acquire all the "remaining space" in column.
  3. Inside that I kept container (Just to put some space between title & list view with margin) this is optional, you can remove container and it will still work.
  4. Now the Listview is well constrained and it won't try to stretch infinitely in column. As Expanded widget already constrained it.

Please correct me if I am wrong anywhere or if this code doesn't work (it works as of now without errors :)

  Column(
    children: <Widget>[
      Text('Leading text widget'),
      ListView(
        shrinkWrap: true,
        physics: NeverScrollableScrollPhysics(),
        children: <Widget>[
          ListTile(
            leading: Icon(Icons.map),
            title: Text('Map'),
          ),
          ListTile(
            leading: Icon(Icons.photo_album),
            title: Text('Album'),
          ),
          ListTile(
            leading: Icon(Icons.phone),
            title: Text('Phone'),
          ),
        ],
      ),
      Text('More widget'),
    ],
  );

just use

shrinkWrap: true,

physics: NeverScrollableScrollPhysics(),

properties in listView

You need to do 2 things:

  • wrap Column inside SingleChildScrollView
  • add shrinkWrap: true and physics: NeverScrollableScrollPhysics() in ListView

Why it works:

As I uderstand, NeverScrollableScrollPhysics disable scrolling of ListView. So, scroll works with SingleChildScrollView. If I am wrong, comment bellow.

SingleChildScrollView(
  child: Column(
    crossAxisAlignment: CrossAxisAlignment.start,
    children: [
      Text('Filter'),
      ListView.separated(
        shrinkWrap: true,
        physics: NeverScrollableScrollPhysics(),
        itemCount: rides.length,
        itemBuilder: (BuildContext context, int index) {
          # return some widget
        }
      ),

Also, you can try use CustomScrollView

CustomScrollView(
      controller: _scrollController,
      slivers: <Widget>[
        SliverList(
          delegate: SliverChildBuilderDelegate(
            (BuildContext context, int index) {
              final OrderModel order = _orders[index];

              return Container(
                margin: const EdgeInsets.symmetric(
                  vertical: 8,
                ),
                child: _buildOrderCard(order, size, context),
              );
            },
            childCount: _orders.length,
          ),
        ),
        SliverToBoxAdapter(
          child: _buildPreloader(context),
        ),
      ],
    );

Tip: _buildPreloader return CircularProgressIndicator or Text

In my case i want to show under ListView some widgets. Use Column does't work me, because widgets around ListView inside Column showing always "up" on the screen, like "position absolute"

Sorry for my bad english

In my case, I was using

  • singleChildScrollView
  • Column
  • Container
  • FutureBuilder - Listview

and I wanted to scroll last scroll view with the whole column for this add

physics: NeverScrollableScrollPhysics(),

this line in your listview.

You can wrap your list Flexible I hope this help you!

 Flexible(
      child: ListView(
          shrinkWrap: true,
          primary: true,
          scrollDirection: Axis.horizontal,
          children: <Widget> [
            Wrap(
              spacing: 12,
              runSpacing: 12,
              children: List<Widget>.generate(5, (index) {
                return MyChip(
                  onChange: (p0) {},
                );
              }),
            )
          ]),
      )

Try using Slivers:

Container(
    child: CustomScrollView(
      slivers: <Widget>[
        SliverList(
          delegate: SliverChildListDelegate(
            [
              HeaderWidget("Header 1"),
              HeaderWidget("Header 2"),
              HeaderWidget("Header 3"),
              HeaderWidget("Header 4"),
            ],
          ),
        ),
        SliverList(
          delegate: SliverChildListDelegate(
            [
              BodyWidget(Colors.blue),
              BodyWidget(Colors.red),
              BodyWidget(Colors.green),
              BodyWidget(Colors.orange),
              BodyWidget(Colors.blue),
              BodyWidget(Colors.red),
            ],
          ),
        ),
        SliverGrid(
          gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 2),
          delegate: SliverChildListDelegate(
            [
              BodyWidget(Colors.blue),
              BodyWidget(Colors.green),
              BodyWidget(Colors.yellow),
              BodyWidget(Colors.orange),
              BodyWidget(Colors.blue),
              BodyWidget(Colors.red),
            ],
          ),
        ),
      ],
    ),
