Page doesnot scroll when nesting ListView in flutter

Question

I have a ListView(2) nested inside another ListView(1).

Whenever I replace 2 with a container, the whole page scrolls fine but as soon as I enable both list views inside each other, both stop scrolling.

This is the main ListView implementation

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: EdgeInsets.all(20.0),
      child: ListView(
        primary: true, //does not have any effect
        physics: const AlwaysScrollableScrollPhysics(),
        children: [
          Container( ...etc.

And this is the second listview implementation inside the first listview:

Expanded(
    child: ListView(
      primary: false,
      padding: const EdgeInsets.only(top: 20.0),
      children: snapshot.map((data) => _buildListItem(context, data)).toList(),
    ),
  );

Expanded cannot be used in a ListView

Try this using SizedBox and setting the height to a desire number

If you want the ListView(2) to take the entire screen (and more) try this:

  Widget build(BuildContext context) {
    return Scaffold(
      body: ListView(
        children: [
          Container(
            color: Colors.pink,
            width: 400,
            height: 800
          ),
          SizedBox(
            height: MediaQuery.of(context).size.height,
            child: ListView(
              children: List.generate(300, (i) => Text(i.toString()))
            ),
          )
        ]
      )
    );
  }

Thank you. Worked Perfectly. Expanded was the problem.

Hey @Josteve how do I make it so that the SizedBox takes as much height as required by the ListView? I am fetching 100 posts from db and users can scroll till the very end. I can't provide that in an static way.

Actually nesting listView inside another is not a good design. Use Slivers instead
