Getting 'Horizontal viewport was given unbounded height.' with TabBarView in flutter

Question

I\'m trying to make a profile page, where the users info is at the top. And then have a tab view below that for different views.

This is the code I\'m using

Answer 1

I solved it by adding TabBar inside Container and TabBarView inside Expanded:

DefaultTabController(
    length: 3,
    child: Column(
      children: <Widget>[
        Container(child: TabBar(..)),
        Expanded(child: TabBarView(..)),
      ],
    ),
  );

Answer 2

based on @Yamin answer I used SizeBox Like below to get full page

    SizedBox.expand(
        child: TabBarView(),
      )

or any other size :

SizedBox(
        height: height:MediaQuery.of(context).size.height // or every other size ,
        child: TabBarView(),
      )

Answer 3

The error description is clear, the TabBarView doesn't have a bounded height. the parent widget also doesn't have a bounded height. So, the Expanded widget will not solve this issue.

EDIT: below solutions are for above question(with columns).In general cases, use a ListView with shrinkWrap: true.(Or any other widgets with shrinkWrap)

There are some options:

First Solution:

Wrap the parent widget(Column) with a limited height widget like SizedBox or AspectRatio. Then use the Expanded widget like this:

child: SizedBox(
          height: 300.0,
          child: Column(
            children: <Widget>[
       .
       .
       .
              Expanded(
                child: TabBarView(
                  children: <Widget>[
                    Container(
                      height: 200.0,
                      color: Colors.grey,
                    ),
                    Container(
                      height: 200.0,
                      color: Colors.green,
                    ),
                    Container(
                      height: 200.0,
                      color: Colors.purple,
                    ),
                  ],
                ),
              ),
            ],
          ),
        ),

Second Solution:

Use a bounded widget like SizedBox or AspectRatio on the TabBarView itself:

SizedBox(
            height: 300.0,
            child: TabBarView(
                children: <Widget>[
                  Container(
                    height: 200.0,
                    color: Colors.grey,
                  ),
                  Container(
                    height: 200.0,
                    color: Colors.green,
                  ),
                  Container(
                    height: 200.0,
                    color: Colors.purple,
                  ),
                ],
              ),
            ),

Note Your can also calcuate the height dynamicly if the height is not static.

Answer 4

try to use IndexedStack instead of TabBarView

i tried Expanded, shrinkWrap = true , ... but no one work's fine just try example.

Example:

class Product extends StatefulWidget {
  @override
  _ProductState createState() => _ProductState();
}

class _ProductState extends State<Product> with SingleTickerProviderStateMixin {
  TabController tabController;
  int selectedIndex = 0;

  @override
  void initState() {
    super.initState();
    tabController = TabController(length: 5, vsync: this, initialIndex: 0);
  }

  @override
  void dispose() {
    tabController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return DefaultTabController(
      length: 3,
      initialIndex: 0,
      child: Scaffold(
        body: ListView(
          shrinkWrap: true,
          children: [
            TabBar(
         
              tabs: <Widget>[
                Tab(
                  text: 'one',
                ),
                Tab(
                  text: 'two',
                ),
                Tab(
                  text: 'three',
                ),
              ],
              controller: tabController,
              onTap: (index) {
                setState(() {
                  selectedIndex = index;
                  tabController.animateTo(index);
                });
              },
            ),
            IndexedStack(
              children: <Widget>[
                Visibility(
                  child: Text('test1'),
                  maintainState: true,
                  visible: selectedIndex == 0,
                ),
                Visibility(
                  child: Text('test2'),
                  maintainState: true,
                  visible: selectedIndex == 1,
                ),
                Visibility(
                  child: Text('test3'),
                  maintainState: true,
                  visible: selectedIndex == 2,
                ),
              ],
              index: selectedIndex,
            ),
          ],
        ),
      ),
    );
  }
}
