To persist AppState locally in Flutter, you implement a custom Persistor class with AsyncRedux to handle readState(), deleteState(), and persistDifference() methods for saving and restoring app data across sessions. You initialize the Store with this persistor and a restored or default initial state.

Throttling in local state persistence controls the frequency of disk writes to optimize performance. By applying throttle control via a custom Persistor, you prevent excessive I/O operations during rapid state changes while ensuring app state is eventually saved.

Yes, this local persistence approach supports app lifecycle pause and resume. You can integrate an AppLifecycleManager to pause persistence operations during background states and resume or persist state actively when the app lifecycle changes.

To restore a default AppState when no saved state exists on disk, initialize the Store with a default initial state. The custom Persistor's readState() method returns null if no prior state is found, triggering the fallback to the default state.

The best way to save only changed state locally is to implement the persistDifference() method in your custom Persistor. This approach captures state deltas instead of serializing the entire AppState, reducing disk write overhead during updates.
