SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps Flutter developers design and implement a consistent, testable data layer that centralizes persistence, avoids direct UI access to storage, and provides offline-capable caching strategies so apps remain reliable and maintainable.

Core Features & Use Cases

  • Decision-driven storage selection: Guides whether to use shared_preferences, SQLite (sqflite/drift), or non-relational stores (Hive/Isar) based on data shape and access patterns.
  • Stateless service wrappers: Encapsulates direct DB and API access into stateless services to simplify testing and isolate side effects.
  • Repository as single source of truth: Implements repositories that guarantee the database is open before operations, transform raw data into domain models, and coordinate sync/merge logic.
  • Use Case: Build a todo app with local persistence, offline-first sync to a remote API, and a repository that presents domain models to the UI layer.

Quick Start

Configure dependencies, answer which entities need persistence, and let the skill scaffold domain models, a stateless database service, and a repository implementation.

Frequently Asked Questions about flutter-databases

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement an offline-first data layer in Flutter with MVVM?▼

An offline-first Flutter architecture uses stateless service wrappers to isolate database and API access, while a repository coordinates sync logic and transforms raw data into domain models before presenting them to the UI layer.

When should I use SQLite vs key-value stores for local persistence in Flutter?▼

You should choose between SQLite and key-value stores based on your data shape and access patterns. SQLite fits relational data, while key-value stores handle simpler non-relational local persistence needs efficiently.

How do I structure a Flutter repository pattern to avoid direct UI access to storage?▼

Structure the repository pattern by encapsulating direct database and API access into stateless services. The repository acts as the single source of truth, transforming raw data into domain models to prevent direct UI access to storage.

Does this Flutter data layer approach work with both sqflite and Hive?▼

Yes, the approach works with sqflite, drift, Hive, and Isar. It guides storage selection dynamically based on whether your app requires relational or non-relational local storage for caching.

Why does my Flutter database service need to be stateless for local caching?▼

Your Flutter database service needs to be stateless to simplify testing and isolate side effects. This encapsulation centralizes persistence logic and ensures the database connection is validated before operations.

Can I use shared_preferences for offline caching in a Flutter MVVM app?▼

Yes, you can use shared_preferences for offline caching when the data shape is simple. The architecture evaluates whether shared_preferences, SQLite, or non-relational stores best fit your specific access patterns.
