Download, cached then display image

## 🚀 Feature Requests
I would like to see the implementation of the functionality when the image is presented in binary form. That is, before the image is displayed, you need to download it, cached and then display it

We have to work with the api, where the images are presented in this form

Example url:
https://images.pexels.com/photos/18013308/pexels-photo-18013308.jpeg?cs=srgb&dl=pexels-gabriel-senna-18013308.jpg

### Platforms affected (mark all that apply)
- [+] :iphone: iOS
- [+] :robot: Android

The issue names no file, test, or entry point. First review the existing Flutter image-loading and caching APIs for the iOS and Android paths, then clarify the expected binary-image behavior and verify that the image is downloaded, cached, and displayed from the supplied API form.
