How to make a SingleChildScrollView with nested ListView? - flutter

Question

I have a list of days, and a list of opening hours for each day.
I need to make the list of days scrollable, and the list of opening hours expands as necessary (= I don't want the list of opening hours to be scrollable into a defined height container).
How to make the list scrollable ?
Here is what I have so far, a list of days that is not scrollable (and I can't see sunday) :
SingleChildScrollView(
child: ListView.builder(
itemCount: _days.length,
itemBuilder: (context, i) {
return Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Padding(
padding: EdgeInsets.all(18.0),
child: Text(_days[i],
style: TextStyle(
fontWeight: FontWeight.bold,
color: Colors.grey[700]))),
Container(
decoration: BoxDecoration(color: Colors.white),
child: ListView.builder(
shrinkWrap: true,
itemCount: _daysDispos[i].length,
itemBuilder: (context, j) {
final dispo = _daysDispos[i][j];
return ListTile(
title: Text(dispo.address.line));
}),
)
],
);
})),
EDIT
In the first listView builder, add :
physics: NeverScrollableScrollPhysics()
Solved my issue.

Answer 1

A good solution would be using Expandable package, and add multiple Expandables inside a single ListView.
Another Solution would be replacing the outer ScrollView with one single ListView, whose Childs will be 7 Columns, each column contains a group of opening hours.

Answer 2

You can try CustomScrollView with multiple SliverLists for your purposes instead of using SingleChildScrollView:
Widget build(BuildContext context) {
return CustomScrollView(
slivers: <Widget>[
SliverList(
delegate: SliverChildListDelegate([
Column(
children: <Widget>[
//Widgets you want to use
],
),
]),
),
SliverList(
delegate: SliverChildListDelegate([
Column(
children: <Widget>[
//Widgets you want to use
],
),
]),
),
],
);
}
