How to stop the spin wheel manually while rotating in progress?
As example below we can start spin wheel by selected.add(1) onTap gesture detector,on while rotating how we stop it manually from code base?

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:flutter_fortune_wheel/flutter_fortune_wheel.dart';

import 'common/common.dart';
import 'router.gr.dart';
import 'util/configure_non_web.dart'
    if (dart.library.html) 'util/configure_web.dart';
import 'widgets/widgets.dart';

class ExampleApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Fortune Wheel Example',
      home: ExamplePage(),
    );
  }
}

class ExamplePage extends StatefulWidget {
  @override
  _ExamplePageState createState() => _ExamplePageState();
}

class _ExamplePageState extends State<ExamplePage> {
  StreamController<int> selected = StreamController<int>();

  @override
  void dispose() {
    selected.close();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    final items = <String>[
      'Grogu',
      'Mace Windu',
      'Obi-Wan Kenobi',
      'Han Solo',
      'Luke Skywalker',
      'Darth Vader',
      'Yoda',
      'Ahsoka Tano',
    ];

    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Fortune Wheel'),
      ),
      body: GestureDetector(
        onTap: () {
          setState(() {
            selected.add(
              Fortune.randomInt(0, items.length),
            );
          });
        },
        child: Column(
          children: [
            Expanded(
              child: FortuneWheel(
                selected: selected.stream,
                items: [
                  for (var it in items) FortuneItem(child: Text(it)),
                ],
              ),
            ),
          ],
        ),
      ),
    );
  }
}

void main() {
  configureApp();
  runApp(DemoApp());
}

class DemoApp extends StatefulWidget {
  @override
  _DemoAppState createState() => _DemoAppState();
}

class _DemoAppState extends State<DemoApp> {
  final _appRouter = AppRouter();

  @override
  Widget build(BuildContext context) {
    return ThemeModeScope(
      builder: (context, themeMode) {
        return MaterialApp.router(
          title: 'Fortune Wheel Demo',
          theme: lightTheme,
          darkTheme: darkTheme,
          themeMode: themeMode,
          routerDelegate: _appRouter.delegate(),
          routeInformationParser: _appRouter.defaultRouteParser(),
        );
      },
    );
  }
}
