Fixes [Compact Visual Density is wrongfully applied to Checkboxes with `MaterialTapTargetSize.padded` on desktop platforms according to Material 3 Guidelines](https://github.com/flutter/flutter/issues/156408) ### Description This PR updates default `Checkbox` visual density to not depend on `ThemeData.visualDenSity` as it will return `VisualDensity.compact` on desktop and break Material 3 guidelines for `Checkbox`. > [!NOTE] > This makes a similar fix as https://github.com/flutter/flutter/pull/110722. ### Code sample <details> <summary>expand to view the code sample</summary> ```dart import 'package:flutter/material.dart'; void main() => runApp(const MyApp()); class MyApp extends StatelessWidget { const MyApp({super.key}); @override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false, home: Scaffold( body: Center( child: Row( mainAxisAlignment: MainAxisAlignment.center, children: [ ColoredBox( color: Colors.amber, child: Checkbox( materialTapTargetSize: MaterialTapTargetSize.padded, value: true, onChanged: (bool? value) {}, ), ), Container( width: 48, height: 48, color: Colors.red, alignment: Alignment.center, child: const Text( '48x48px', style: TextStyle(fontSize: 10, color: Colors.white), ), ) ], ), ), ), ); } } ``` </details> <img width="577" alt="Screenshot 2024-11-18 at 18 02 01" src="https://github.com/user-attachments/assets/d390c92f-dd62-4c42-b6b7-d4f101078618"> <img width="577" alt="Screenshot 2024-11-18 at 18 01 49" src="https://github.com/user-attachments/assets/632e8d19-11bf-45c7-9be9-5c4fc308f3ea"> ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [ ] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
