How to add a ListView to a Column in Flutter?

Question

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),
          ),
        ),
      );

Answer 1

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 Container with height:

Container(
  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"),
      )
    ],
  ),
)

Answer 2

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

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

Answer 3

Reason for the 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(
         child: ListView(...),
       )
     ],
   )
   

---

2. If you want to limit your ListView to certain height, you can use SizedBox.

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

---

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

   Column(
     children: <Widget>[
       ListView(
         shrinkWrap: true, // use it
       )
     ],
   )
   

Answer 4

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.

Answer 5

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,

Answer 6

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
         ],
       ),

     ],
   ), 
  );

Answer 7

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),
    )
  ],
));

}

Answer 8

Here is a very simple method. There are a different ways to do it, like you can get it by Expanded, Sizedbox or Container and it should be used according to needs.

1. Use Expanded : A widget that expands a child of a Row, Column, or Flex so that the child fills the available space.

   Expanded(
       child: ListView(scrollDirection: Axis.horizontal,
           children: <Widget>[
             OutlineButton(onPressed: null,
                 child: Text("Facebook")),
             Padding(padding: EdgeInsets.all(5.00)),
             OutlineButton(onPressed: null,
                 child: Text("Google")),
             Padding(padding: EdgeInsets.all(5.00)),
             OutlineButton(onPressed: null,
                 child: Text("Twitter"))
           ]),
     ),
   

Using an Expanded widget makes a child of a Row, Column, or Flex expand to fill the available space along the main axis (e.g., horizontally for a Row or vertically for a Column).

2. Use SizedBox : A box with a specified size.

   SizedBox(
       height: 100,
       child: ListView(scrollDirection: Axis.horizontal,
           children: <Widget>[
             OutlineButton(
                 color: Colors.white,
                 onPressed: null,
                 child: Text("Amazon")
             ),
             Padding(padding: EdgeInsets.all(5.00)),
             OutlineButton(onPressed: null,
                 child: Text("Instagram")),
             Padding(padding: EdgeInsets.all(5.00)),
             OutlineButton(onPressed: null,
                 child: Text("SoundCloud"))
           ]),
    ),
   

If given a child, this widget forces its child to have a specific width and/or height (assuming values are permitted by this widget's parent).

3. Use Container : A convenience widget that combines common painting, positioning, and sizing widgets.

    Container(
       height: 80.0,
       child: ListView(scrollDirection: Axis.horizontal,
           children: <Widget>[
             OutlineButton(onPressed: null,
                 child: Text("Shopify")),
             Padding(padding: EdgeInsets.all(5.00)),
             OutlineButton(onPressed: null,
                 child: Text("Yahoo")),
             Padding(padding: EdgeInsets.all(5.00)),
             OutlineButton(onPressed: null,
                 child: Text("LinkedIn"))
           ]),
     ),
   

The output to all three would be something like this

Answer 9

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) {
            ...
        },
        ),
    ),
],

);

Answer 10

  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

Answer 11

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

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 :)

Answer 12

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),
            ],
          ),
        ),
      ],
    ),
  ),
)

Answer 14

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

Answer 15

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
        }
      ),
