flutter-caching-and-performance

1. Evaluate data retention requirements and select a caching strategy (in-memory, shared preferences, file system, or database).

2. Implement the chosen caching mechanism using appropriate Flutter packages (e.g., `sqflite`, `path_provider`).

3. Implement an offline-first repository pattern with stream-based data delivery.

4. Optimize image and scroll caching to prevent memory bloat and layout passes.

5. Validate and fix performance issues by reviewing code for common pitfalls.

6. Implement FlutterEngine caching for Android to reduce warm-up time (if applicable).
