[Bug]: PackageInfo does not overwrite Hashcode and equals

Platform

testing

Plugin

package_info_plus

Version

3.0.1

Flutter SDK

3.3.6

Steps to reproduce

I stumbled across this issue when I wanted to use PackageInfo in a test and could not properly compare two instances as hashcode and equals is not overwritten.

https://github.com/fluttercommunity/plus_plugins/blob/main/packages/package_info_plus/package_info_plus/lib/package_info_plus.dart

Code Sample

mockValue = PackageInfo(
            appName: 'test',
            packageName: 'test',
            version: 'test',
            buildNumber: 'test',
          );

... execute test

expect(result, equals(PackageInfo(
          appName: 'test',
          packageName: 'test',
          version: 'test',
          buildNumber: 'test',
        )));

Logs

Expected: [Instance of 'PackageInfo']
    Actual: [Instance of 'PackageInfo']
     Which: at location [0] is <Instance of 'PackageInfo'> instead of <Instance of 'PackageInfo'>
  
  WARNING: Please ensure state instances extend Equatable, override == and hashCode, or implement Comparable.

It is always a good idea to use your own data objects instead of using the ones provided by 3rd parties in situations like this. But a PR with the overrides for equals and toString would be welcome if anyone wants to submit it.
