Menu
In my Flutter project, in one page I have some rows including card align vertically. Now, I want this screen to make scroll-able.
I have tried replacing the column to Listview but it didn't work. I also tried to wrap it with SingleChildScrollview but didn't work. It shows like below image-
Here's the code -
HomeFragment.dart
class HomeFragment extends StatefulWidget {
@override
_HomeFragmentState createState() => new _HomeFragmentState();
}
String jwt;
class _HomeFragmentState extends State<HomeFragment> {
List<LastEngagement> _lastEngagements = List<LastEngagement>();
@override
void initState() {
super.initState();
_getLastEngagement;
_getLastEngagement2();
}
void _getLastEngagement() {
Webservice().load(LastEngagement.allLastEngagement).then((newsArticles) => {
setState(() => {
_lastEngagements = newsArticles
})
});
}
void _getLastEngagement2() {
Webservice().load(LastEngagement.allLastEngagement).then((newsArticles) => {
setState(() => {
_lastEngagements = newsArticles
})
});
}
Card showCard(int index) {
return new Card(

],

Replacing the Column by Listview causes following error-
So, I need a permanent solution to make my screen scroll-able, doesn't matter whatever widgets I use.

Method 2: ListView(): You can make a scrolling page using ListView() widget as well. Furthermore, you can change the scroll direction to Horizontal.
You can use SingleChildScrollView or change the column widget to ListView
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('News'),
),
body: SingleChildScrollView(
child: Column(
children: <Widget>[
],
),
));
}
Or
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('News'),
),
body: ListView(
children: <Widget>[],
));
}

Well the previous answers do contain the solution .. at least that's what I think .. but they are buggy answers and that's why it's not working .. try this
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("News"),
),
body: Column(
children: <Widget>[
Expanded(
child: SingleChildScrollView(),
)
],
),
);
}
The expanded gives SingleChildScrollView() full height of the screen allowing it to work :) I think it should work . Good luck
