SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a unified, reactive data layer abstraction for Dart and Flutter applications, simplifying data management across various storage backends and enabling real-time data synchronization.

Core Features & Use Cases

  • Unified Backend Interface: Use a single API for multiple storage solutions like PowerSync, Drift, and others.
  • Reactive Streams: Leverage RxDart for immediate data and real-time updates.
  • Policy-Based Operations: Implement fetching strategies like cache-first or network-first.
  • Offline Sync Management: Handles CRUD operations and queue cleanup for offline capabilities.
  • Use Case: Manage user profiles, bookings, and financial transactions with consistent data access, whether online or offline, ensuring data integrity and real-time updates across the application.

Quick Start

Initialize a NexusStore with an InMemoryBackend and perform a save operation on a User object.

FAQPage Schema
How do I manage offline sync and CRUD operations in Flutter with multiple database backends?

A unified reactive data store abstraction manages offline sync and CRUD operations across multiple backends like PowerSync and Drift in Flutter. It provides a single API for consistent data access whether online or offline.

What is a reactive data store in Dart and how does it handle real-time streams?

A reactive data store in Dart uses RxDart to provide immediate data and real-time updates via streams. It manages data consistency by pushing changes to the UI automatically as the underlying storage updates.

Does this unified data store abstraction support PowerSync and Drift simultaneously?

Yes, the unified backend interface supports multiple storage solutions including PowerSync and Drift simultaneously. You can use a single API to interact with these diverse storage solutions without changing your data access logic.

How do I implement cache-first or network-first fetching strategies in Flutter?

You implement cache-first or network-first fetching strategies using policy-based operations within the data store. This allows you to define how data is retrieved from the backend based on your application's connectivity requirements.

What is the best way to handle data consistency for offline Flutter applications?

The best way to handle data consistency offline is using a data store that manages queue cleanup and CRUD operations during disconnections. It ensures data integrity and synchronizes transactions automatically when connectivity is restored.

Can I use an in-memory backend for quick Flutter data store initialization and testing?

Yes, you can initialize the data store with an InMemoryBackend to perform quick save and read operations. This is useful for local testing and development before connecting to persistent storage solutions.
