Selecting a Caching Strategy

Apply the appropriate caching mechanism based on the data lifecycle and size requirements.

If storing small, non-critical UI states or preferences: Use shared_preferences.

If storing large, structured datasets: Use on-device databases (SQLite via sqflite, Drift, Hive CE, or Isar).

If storing binary data or large media: Use file system caching via path_provider.

If retaining user session state (navigation, scroll positions): Implement Flutter's built-in state restoration to sync the Element tree with the engine.

If optimizing Android initialization: Pre-warm and cache the FlutterEngine.
