What is the alternative to RecyclerView in Flutter?
What is the alternative to Recycle view in flutter I have tried using this code but how to do Animination with listview widget in flutter
Is this valid?
ListView(
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'),
),
],
);
Solution 1:
ListView
:
Usually this should be used with a small number of children as the List will also construct the invisible elements in the list and a large amount of elements may render this inefficient.
ListView.builder()
:
The list items are constructed lazily, meaning only a specific number of list items are constructed and when a user scrolls ahead, the earlier ones are destroyed.
More info is here.
Solution 2:
Following flutter-for/android-devs
The recommended, efficient, and effective way to build a list uses a ListView.Builder. This method is great when you have a dynamic List or a List with very large amounts of data. This is essentially the equivalent of RecyclerView on Android, which automatically recycles list elements for you:
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Sample App"),
),
body: ListView.builder(
itemCount: widgets.length,
itemBuilder: (BuildContext context, int position) {
return getRow(position);
}));
}
Widget getRow(int i) {
return GestureDetector(
child: Padding(
padding: EdgeInsets.all(10.0),
child: Text("Row $i")),
onTap: () {
setState(() {
widgets.add(getRow(widgets.length + 1));
print('row $i');
});
},
);
}
