ListTile OnTap is working when I use ListView. But when i use ListWheelScrollView it doesn't work. I mean it doesn't get tapped. The view changes. But i can't seem to tap it. I looked for the solution in a lot of places and links but still couldn't find the solutions.
These are the code I did.
@override
Widget build(BuildContext context) {
return new ListWheelScrollView(
physics:FixedExtentScrollPhysics(),
children: getPostList(),
itemExtent: 100.0,
);
}
List<PostListItem> getPostList() {
return _postModal
.map((contact) => new PostListItem(contact))
.toList();
}
And this is where I have built the ListTile
@override
Widget build(BuildContext context) {
return new ListTile(
onTap: () {
var route = new MaterialPageRoute(
builder: (BuildContext context) =>
new OnTapPost(value: _postModal.fullName),
);
Navigator.of(context).push(route);
},
leading: new Image.asset('assets/images/logo.png'),
title: new Text(_postModal.fullName),
subtitle: new Text(_postModal.email)
);
}
In the above code the list items doesn't get tapped. But if i replace the ListWheelScrollView with ListView as shown below, it works perfectly.
@override
Widget build(BuildContext context) {
return new ListView(
children: getPostList(),
);
}
List<PostListItem> getPostList() {
return _postModal
.map((contact) => new PostListItem(contact))
.toList();
}
Update: Another look no update yet from the flutter team but another hack solution. By wrapping the whole listscrollwheel widget with a Gesturedetector. Every scroll sets the state using the "onSelectedItemChanged" for listscrollview. But the gesture detector widget does something with it only on tap.
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
class ServicesList extends StatefulWidget {
final type;
ServicesList({this.type});
@override
_ServicesListState createState() => _ServicesListState();
}
class _ServicesListState extends State<ServicesList> {
double _height ,_width;
int serviceIndex;
final FixedExtentScrollController _controller = FixedExtentScrollController();
List<Service> serviceList = [
Service(name: 'service 1'),
Service(name: 'service 4'),
Service(name: 'service 3'),
];
@override
void initState() {
serviceIndex = 0;
// TODO: implement initState
super.initState();
}
detectService(index) {
print('clicked container : $index'); //do whatever you want with the clicked index
}
@override
Widget build(BuildContext context) {
_height = MediaQuery.of(context).size.height;
_width = MediaQuery.of(context).size.width;
return scrollWheel();
}
Widget scrollWheel() {
return GestureDetector(
onTap: (){
detectService(serviceIndex);
},
child: ListWheelScrollView(
controller: _controller,
diameterRatio: 1.5,
itemExtent: 80,
onSelectedItemChanged: (e)=>{
setState(() {
serviceIndex = e;
})
},
magnification: 0.2,
physics: FixedExtentScrollPhysics(),
children: serviceList.map((e) {
return Container(
padding: const EdgeInsets.all(6.0),
alignment: Alignment.center,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10.0),
color: Colors.blue,
),
child:Text('item $e.name');
);
}).toList(), //List of widgets
),
);
}
}
class Service {
String name;
Service( {this.name} );
}
