Publishing custom cache manager implementation best practices

## 💬 Questions and Help

**Background**: I extended `BaseCacheManager` to create a custom cache that uses [Firebase Performance](https://pub.dev/packages/firebase_performance) to trace HTTP network requests.

Implementation wise, it's very simple: Just like [DefaultCacheManager](https://github.com/Baseflow/flutter_cache_manager/blob/28b8d182d3de8e4e9ce6edaca8e85ad15d052d21/flutter_cache_manager/lib/src/cache_manager.dart#L30) with a custom [FileService](https://github.com/Baseflow/flutter_cache_manager/blob/28b8d182d3de8e4e9ce6edaca8e85ad15d052d21/flutter_cache_manager/lib/src/web/file_service.dart#L21) class that traces requests inside `get(...)`. It uses the `firebase_performance` sdk to create the traces, just a few lines of code.

I am considering publishing this as a pub package. This would help alleviate some common issues and feature requests for Firebase Performance related to automatic network tracing.

**Question**: Are there any best practices for publishing a custom cache manager implementation as a pub package? Are there examples of other published cache manager implementations?

Specifically, I'm looking for:
- Package naming convention to imply its builds off of this package
- How to show it works with `cached_network_image`, or any other package that uses `flutter_cache_manager` under the hood
- If there is some wiki page that contains all known custom cache implementations that I should add it to

参照されている cache_manager.dart と web/file_service.dart の例から始め、その後、リポジトリに既存のドキュメントと package に関するガイダンスを確認してください。完了条件は、package の命名、cached_network_image またはその他の利用側との互換性、カスタム実装をどこに一覧化すべきかを網羅した回答が文書化されていることです。
