circle_wheel_scroll Detect Pressed Item

Greetings, I have tried to wrap the children of CircleListScrollView widget with GestureDetector and FlatButton to execute onTap or onPressed callbacks but none of them is getting called. Also I tried to do the same in ListWheelScrollView and got the same result. Is there a way to detect the pressed item in the list or just by using onSelectedItemChanged ?

I'm afraid that issue with gesture detection are connected with ListWheelScrollView (on which my widget is based on). I've changed my example to use ListWheelScrollView, and didn't get anything from GestureDetector. Here is code

import 'package:flutter/material.dart';

class WheelExample extends StatelessWidget {
  Widget _buildItem(BuildContext context, int i) {
    return GestureDetector(
      onTap: () { print('TAP ON ITEM'); },
          child: Center(
        child: ClipRRect(
          borderRadius: BorderRadius.circular(40),
          child: Container(
            width: 80,
            padding: EdgeInsets.all(20),
            color: Colors.blue[100 * ((i % 8) + 1)],
            child: Center(
              child: Text(
                i.toString(),
              ),
            ),
          ),
        ),
      ),
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Wheel example'),
      ),
      body: SafeArea(
        child: Center(
          child: Container(
            child: ListWheelScrollView.useDelegate(
              itemExtent: 80,
              childDelegate: ListWheelChildBuilderDelegate(
                childCount: 10,
                builder: _buildItem,
              ),
            ),
          ),
        ),
      ),
    );
  }
}


class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: WheelExample(),
    );
  }
}

void main() => runApp(MyApp());

Feel free to open issue on flutter repo.
