Enable use of `http` or `dio` library for making network requests

[ueman]

🚀 Feature Requests

I would like to use this package with either http or dio.

Contextualize the feature

This would enable me to

• make use of cupertino_http and cronet_http, and as a result it would allow me to enable the app being used with a VPN on iOS.
• Would allow me to trace image requests with Sentry, or similar APM tools.

Describe the feature

I would like to be able to pass my own http.Client or Dio instance, which is then used to make the network request.

Platforms affected (mark all that apply)

• [x] :iphone: iOS

@ueman would you be able to make a PR for this?

There is a package for that, just needed to create a cache manager which uses a custom http file service:
