flutter-core:flutter-persistence

What problem does it solve?

This skill provides a structured blueprint for implementing multi-layer local data persistence in Flutter, enabling apps to operate reliably offline and cache data efficiently.

Core Features & Use Cases

• Supports key-value storage with SharedPreferences and Hive for fast, lightweight settings and state.
• Supports relational storage with SQLite (via sqflite) and Drift for complex data models and migrations.
• Supports file storage via path_provider for large or binary assets, enabling offline archives and document management.
• Includes offline-first patterns, data caching strategies, and migration guidance across platforms (mobile, desktop, web).

Quick Start

Create a Flutter project and add the persistence dependencies (SharedPreferences, Hive, path_provider, sqflite, drift). Initialize Hive in your app startup and open a box for settings. Implement a tiny repository to save a sample setting in SharedPreferences, then extend to Hive for caching and Drift for relational data, and persist a sample file with path_provider.
