Building a Pull-Through Cache in Flutter with Drift, Firestore, and SharedPreferences

Hey fellow Flutter and Dart Devs!

I wanted to share a pull-through caching strategy we implemented in our app, MyApp, to manage data synchronization between a remote backend (Firestore) and a local database (Drift). This approach helps reduce backend reads, provides basic offline capabilities, and offers flexibility in data handling.

The Goal

Create a system where the app prioritizes fetching data from a local Drift database. If the data isn't present locally or is considered stale (based on a configurable duration), it fetches from Firestore, updates the local cache, and then returns the data.

loginr=s.post('https://www.mysubaru.com/login', data = {'username':username,'password':password})
#should return a response 200
