Inspired by Bitcask. Documentation & Samples 📖 If you need queries, multi-isolate support or links between objects check out Isar Database. Features 🚀 Cross platform: mobile, desktop, browser ⚡ Great performance (see benchmark) ❤️ Simple, powerful, & intuitive API 🔒 Strong encryption built in 🎈 NO native dependencies 🔋 Batteries included Getting Started Check out the Quick Start documentation to get started. Usage You can use Hive just like a map. It is not necessary to await Futures. var box = Hive.box('myBox'); box.put('name', 'David'); var name = box.get('name'); print('Name: $name'); Store objects Hive not only supports primitives, lists and maps but also any Dart object you like. You need to generate a type adapter before you can store objects. @HiveType(typeId: 0) class Person extends HiveObject { @HiveField(0) String name; @HiveField(1) int age; } Extending HiveObject is optional but it provides handy methods like save() and delete(). var box = await Hive.openBox('myBox'); var person = Person() ..name = 'Dave' ..age = 22; box.add(person); print(box.getAt(0)); // Dave - 22 person.age = 30; person.save(); print(box.getAt(0)) // Dave - 30 Hive ❤️ Flutter Hive was written with Flutter in mind. It is a perfect fit if you need a lightweight datastore for your app. After adding the required dependencies and initializing Hive, you can use Hive in your project: import 'package:hive/hive.dart'; import 'package:hive_flutter/hive_flutter.dart'; class SettingsPage extends StatelessWidget { @override Widget build(BuildContext context) { return ValueListenableBuilder( valueListenable: Hive.box('settings').listenable(), builder: (context, box, widget) { return Switch( value: box.get('darkMode'), onChanged: (val) { box.put('darkMode', val); } ); }, ); } } Boxes are cached and therefore fast enough to be used directly in the build() method of Flutter widgets. Benchmark 1000 read iterations 1000 write iterations SharedPreferences is on par with Hive when it comes to read performance. SQLite performs much worse. Hive greatly outperforms SQLite and SharedPreferences when it comes to writing or deleting. The benchmark was performed on a Oneplus 6T with Android Q. You can run the benchmark yourself. *Take this benchmark with a grain of salt. It is very hard to compare databases objectively since they were made for different purposes.
