Flutter database to store & sync objects across devices with sustainable offline-first approach
🏁 High performance on restricted devices, like IoT gateways, micro controllers, ECUs etc.
🪂 Resourceful with minimal CPU, power and Memory usage for maximum flexibility and sustainability
🔗 Relations: object links / relationships are built-in
💻 Multiplatform: Linux, Windows, Android, iOS, macOS
🌱 Scalable: handling millions of objects resource-efficiently with ease
💐 Queries: filter data as needed, even across relations
🦮 Statically typed: compile time checks & optimizations
📃 Automatic schema migrations: no update scripts needed
And much more than just data persistence
👥 ObjectBox Sync: keeps data in sync between devices and servers
🕒 ObjectBox TS: time series extension for time based data
To start using ObjectBox in your Flutter/Dart app, head over to
- the objectbox pub.dev page or
- check out our Getting Started guide.
If you'd like to contribute to the package as a developer, hack around, or just have a look at the code, you can
clone/check out this repository and run ./tool/init.sh to regenerate code and get you started. Make sure to have a
look at the contribution guidelines - all contributions are very welcome.
This repository holds all ObjectBox Dart/Flutter packages as separate directories:
- objectbox - main library code
- objectbox_generator - code generator
- objectbox_flutter_libs - core binary library dependency for Flutter (Android/iOS) - no dart/flutter code
- objectbox_sync_flutter_libs - core binary library dependency with ObjectBox Sync enabled
- benchmark - used internally to microbenchmark and compare various implementations during development of objectbox-dart
There's also a separate repository benchmarking objectbox (and other databases) in Flutter: objectbox-dart-performance. And another one testing and comparing the performance of our FlatBuffers fork vs the upstream version: flatbuffers-benchmark.
ObjectBox supports multiple platforms and languages:
- ObjectBox Java / Kotlin: runs on Android, desktop, and servers.
- ObjectBox Swift: build fast mobile apps for iOS (and macOS)
- ObjectBox Go: great for data-driven tools and embedded server applications
- ObjectBox C and C++: native speed with zero copy access to FlatBuffer objects
We strive to bring joy to Flutter developers and appreciate all kinds feedback, both positive and negative. What do you love? What's amiss? Where do you struggle in everyday app development?
