flutter-caching-data

Implements caching strategies for Flutter apps, covering offline-first data sync, local persistence with SQLite and Hive, image and scroll caching, and FlutterEngine pre-warming on Android. It walks through repository patterns that serve local data first, then sync with remote APIs in the background. Gives you concrete patterns for each caching layer in Flutter instead of piecing together scattered docs for sqflite, cached_network_image, state restoration, and engine pre-warming separately.
