ObjectBox Sync Flutter 라이브러리는 Flutter 앱을 위한 고성능 실시간 데이터베이스 솔루션을 제공하여 장치 및 플랫폼 간에 Dart 객체를 원활하게 동기화할 수 있게 합니다. ObjectBox 커널 기반으로 구축되어 오프라인 우선 데이터 관리, 자동 충돌 해결 및 네트워크를 통한 효율적인 동기화를 지원합니다. 빠른 로컬 저장소와 여러 클라이언트 간의 동기화된 데이터가 필요한 앱에 적합하며, 최소한의 설정으로 Flutter 프로젝트에 직접 통합됩니다. Android, iOS, macOS, Windows, Linux에서 작동하므로 신뢰할 수 있고 낮은 지연 시간의 데이터 지속성과 동기화가 필요한 크로스플랫폼 앱에 적합합니다.
Flutter database with vector support - easy to use & fast Dart object persistence, plus on-device vector search 💙
Very first on-device vector database for Flutter / Dart AI apps. Intuitive APIs, simply fast.
Persist local Dart objects with ease & speed, efficiently manage vectors.
ObjectBox provides a store with boxes to put objects into:
// Annotate a Dart class to create a Box@Entity()
classPerson{
@Id()
int id;
String firstName;
String lastName;
Person({this.id = 0, requiredthis.firstName, requiredthis.lastName});
}
finalStore store = awaitopenStore(directory: 'person-db');
final box = store.box<Person>();
var person = Person(firstName: 'Joe', lastName: 'Green');
final id = box.put(person); // Create
person = box.get(id)!; // Read
person.lastName = 'Black';
box.put(person); // Update
box.remove(person.id); // Deletefinal query = box // Query
.query(Person_.firstName.equals('Joe') & Person_.lastName.startsWith('B'))
.build();
finalList<Person> people = query.find();
query.close();
ObjectBox Flutter database is an excellent choice for storing Dart objects in cross-platform
applications and the only on-device database that offers you vector support for your on-device AI apps.
Designed for high performance, the ObjectBox Flutter database is excellent for mobile
and IoT devices. ObjectBox consumes minimal CPU, memory, and battery, ensuring that your software is
not only efficient but also sustainable. By storing data locally on the device, ObjectBox allows you
to cut cloud costs and create an app that does not require a connection. Get started with our
intuitive native Dart API in minutes, without the hassle of SQL.
Plus: We built a data synchronization solution that allows you to keep data in sync across devices
and servers, both online and offline.
🏁 High performance - superfast response rates enabling real-time applications.
🪂 ACID compliant - Atomic, Consistent, Isolated, Durable.
💻 Multiplatform - Android, iOS, macOS, Linux, Windows, any POSIX-system.
🌱 Scalable - grows with your app, handling millions of objects with ease.
💚 Sustainable - frugal on CPU, Memory and battery / power use, reducing CO2 emissions.
🔗 Relations - object links / relationships are built-in.
💐 Queries - filter data as needed, even across relations.
🦮 Statically typed - compile time checks & optimizations.
📃 Schema migration - change your model with confidence.
Oh, and there is one more thing...
😮 Data Sync - keeps data in sync offline or online, between devices and servers.
Getting Started
Continue with our ➡️ Getting Started guide. It has resources and video tutorials on how to use ObjectBox in your Flutter or Dart app.
How does ObjectBox compare to other solutions?
ObjectBox is fast. Have a look at our benchmarks below, or test it for yourself
It's a full NoSQL SQLite alternative with intuitive Dart APIs you'll love 💙
It comes with an out-of-the-box Data Sync, making it an effective self-hosted Firebase alternative
Flutter Database Performance Benchmarks
We tested across the four main database operations, CRUD (create, read, update, delete).
Each test was run multiple times and executed manually.
Data preparation and evaluation were done outside the measured time.
Here are the benchmarks for ObjectBox vs sqflite vs Hive (last updated 2021-09-11) 👇
Do you want to check out the ObjectBox code itself? E.g. see it in action, run tests, or even contribute code?
Great! Clone/check out this repository and run this to generate code and get you started quickly:
