### Flutter Switch Theming Example with Shrine Theme

Source: https://github.com/material-components/material-components-flutter/blob/develop/docs/components/switches.md

Demonstrates how to apply a custom Material Theme, specifically the Shrine theme, to Flutter Switches. This example includes a `Switch` widget within a `ListTile` and shows how to manage the switch's state and disable it. It also defines custom `ColorScheme`, `IconThemeData`, and `TextTheme` for the theme.

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      debugShowCheckedModeBanner: false,
      home: MyHomePage(),
      theme: _buildShrineTheme(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  List<bool> _values = [true, false, true, false, false];

  Widget build(BuildContext context) {
    final int count = 4;

    return Scaffold(
      body: Column(
        children: <Widget>[
          for (int i = 0; i <= count; i++)
            ListTile(
              title: Text(
                'Switch ${i + 1}',
                style: Theme.of(context).textTheme.subtitle1.copyWith(
                    color: i == count ? Colors.black38 : Colors.black),
              ),
              leading: Switch(
                value: _values[i],
                onChanged: i == count
                    ? null
                    : (bool value) {
                        setState(() {
                          _values[i] = value;
                        });
                      },
