ListWheelScrollView children do not respond on gesture (onTap) events #38803
Description
Steps to Reproduce
Hi! Here is my widget that uses ListWheelScrollView with FixedExtentScrollController:
import 'package:flutter/material.dart';
class LetterWheel extends StatefulWidget {
const LetterWheel({Key key}) : super(key: key);
@override
_LetterWheelState createState() => _LetterWheelState();
}
class _LetterWheelState extends State<LetterWheel> {
FixedExtentScrollController scrollController;
@override
void initState() {
scrollController = FixedExtentScrollController();
super.initState();
}
@override
void dispose() {
scrollController.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
return ListWheelScrollView(
controller: scrollController,
physics: const FixedExtentScrollPhysics(),
itemExtent: 110,
children: ['A', 'B', 'C', 'D', 'E', 'F', 'G']
.map(
(letter) => Container(
margin: const EdgeInsets.all(10),
height: 90,
color: Colors.yellow,
child: GestureDetector(
onTap: () => print('Letter "$letter" is pressed.'),
child: Center(
child: Text(
letter,
style: const TextStyle(fontSize: 20, fontWeight: FontWeight.bold),
),
),
),
),
)
.toList(),
);
}
}Expected result: When the list item is tapped the message is printed to the console.
Actual result: When the list item is tapped nothing happens.
Here is my flutter doctor -v output:
