flutter-caching

What problem does it solve?

This Skill reduces startup latency, minimizes network usage, and provides robust offline-first persistence for Flutter applications by selecting and implementing the appropriate local caching strategies and performance optimizations.

Core Features & Use Cases

• Adaptive Caching Strategies: Choose between in-memory, shared_preferences, file-system caching, and on-device databases (sqflite) based on data size and access patterns.
• Offline-First Repositories: Stream-based flows that yield cached data immediately and refresh from network, with cache updates and graceful error handling.
• Android FlutterEngine Caching & Performance Tuning: Pre-warm and manage cached FlutterEngine instances to reduce UI warm-up time, plus image cache and scroll cache optimizations to prevent GPU and layout bloat.
• Use Case: Provide instant access to a user's profile and image feed offline while syncing updates in the background and ensuring fast navigation to Flutter screens embedded in an Android host app.

Quick Start

Implement file system caching for large JSON blobs using path_provider and dart:io and provide a reusable Dart FileCacheService implementation.
