Question 1

How do I set up ObjectBox in a Flutter project?

Accepted Answer

Start by adding the objectbox and objectbox_flutter_libs dependencies, annotate your Dart classes with @Entity, run the code generator, and initialize the store using openStore. The README provides a basic example and links to the Getting Started guide for detailed steps.

Question 2

ObjectBox vs SQLite for Flutter: which is better?

Accepted Answer

ObjectBox is faster and offers a NoSQL, Dart-native API, making it superior for performance-critical and AI applications. SQLite is better if you need full SQL support, a wider ecosystem, and simpler setup without code generation.

Question 3

Does ObjectBox support offline data sync?

Accepted Answer

Yes, ObjectBox Sync enables data synchronization across devices and servers both online and offline. However, this requires additional setup with the objectbox_sync_flutter_libs package and may involve licensing, as noted in the documentation.

Question 4

Accepted Answer

Use the on-device vector search capabilities by storing vectors as part of your objects and utilizing the vector query APIs. Refer to the official documentation on on-device ANN vector search for specific implementation examples and best practices.

Question 5

Is ObjectBox free to use in commercial applications?

Accepted Answer

The core code is under the Apache License 2.0, but components like ObjectBox Sync may have different licenses. Check the ObjectBox website for details on commercial use, as the README mentions varying licenses for different components.

Question 6

What are the main limitations of ObjectBox database?

Accepted Answer

Key limitations include the lack of advanced SQL features, dependency on code generation, and potential vendor lock-in. It's also primarily designed for Dart, so integration with other languages is limited compared to more universal databases.
