Create request caching service

[ethanwlee]

This request caching service will be used to:

1. make requests to url
2. return cached data for url
3. request new data from backend at url
4. update cache for url

callers of this will get two responses, like a stream of data where the first response is the cached response and the second response is the network response

perhaps using this as a custom hook similar to https://tanstack.com/query/latest

@ethan-tbd,

I have implemented a solution that closely matches your requirements. You can find the example code here:

Flutter Caching Hook GitHub Repository

Please review it and let me know if it meets your needs. Additionally, I've provided a recording of the implementation for your reference:

caching.screen.record.mp4

Approach:

1. Used SharedPreferences to store cache data persistently across sessions.
2. Utilized streams to send multiple responses from the function, ensuring that the first response is the cached data and the subsequent one is the fresh network data.
3. Updated the UI with StreamBuilder based on the data received from the stream, providing a seamless user experience.
