Overview
Realm Dart is the official database SDK for Dart, designed for mobile and desktop applications. It provides a fast, flexible, and scalable NoSQL solution that replaces traditional options like SQLite or key-value stores. Realm enables real-time data synchronization, seamless object-oriented data modeling, and efficient querying with minimal boilerplate. Built specifically for Flutter and other Dart-based platforms, it supports offline-first development and automatic data persistence across Android, iOS, macOS, Windows, and Linux. Its reactive nature ensures UIs stay in sync with data changes.
