The simplest way to store data in Dart & Flutter. Start with just 3 lines of code, scale to millions of records.
🆕 Version 1.4.0: Introducing Simple API - Zero configuration, 3 lines to start! See changelog
// That's it! You're ready to go
final db = await ReaxDB.simple('myapp');
await db.put('user', {'name': 'John', 'age': 30});
final user = await db.get('user');✅ Dead Simple - Start with 3 lines, no configuration needed
✅ Blazing Fast - 21,000+ writes/second, instant cache reads
✅ Scale When Ready - From simple key-value to advanced queries
✅ Pure Dart - Works everywhere: iOS, Android, Web, Desktop, Server
✅ Production Ready - ACID transactions, encryption, real-time sync
dependencies:
reaxdb_dart: ^1.4.0import 'package:reaxdb_dart/reaxdb_dart.dart';
// Open database
final db = await ReaxDB.simple('myapp');
// Store any JSON data
await db.put('user:1', {
'name': 'Alice',
'email': '[email protected]',
'age': 25
});
// Get data
final user = await db.get('user:1');
print(user['name']); // Alice
// Query with patterns
final users = await db.getAll('user:*');
users.forEach((key, value) {
print('$key: ${value['name']}');
});
// Delete data
await db.delete('user:1');
// Close when done
await db.close();// Listen to changes
db.watch('user:*').listen((event) {
print('User ${event.key} changed');
});
// Make changes - listeners are notified automatically
await db.put('user:2', {'name': 'Bob'});// Store multiple items at once
await db.putAll({
'user:1': {'name': 'Alice'},
'user:2': {'name': 'Bob'},
'user:3': {'name': 'Charlie'},
});
// Delete multiple items
await db.deleteAll(['user:1', 'user:2']);- 📱 Mobile apps needing offline-first storage

ReaxDB grows with your app. When you need advanced features, they're one line away:
// Need transactions? ✅
await db.advanced.transaction((txn) async {
// Your atomic operations here
});
// Need indexes for complex queries? ✅
await db.advanced.createIndex('users', 'age');
final youngUsers = await db.advanced.collection('users')
.whereBetween('age', 18, 25)
.find();
// Need encryption? ✅
final secureDb = await ReaxDB.simple('myapp', encrypted: true);📚 See Advanced Documentation for transactions, indexes, aggregations, and more.
// Store todos
await db.put('todo:1', {
'title': 'Buy milk',
'done': false,
'created': DateTime.now().toIso8601String()
});
// Get all todos
final todos = await db.getAll('todo:*');
// Mark as done
final todo = await db.get('todo:1');
todo['done'] = true;
await db.put('todo:1', todo);// Save settings
await db.put('settings', {
'theme': 'dark',
'notifications': true,
'language': 'en'
});
// Read settings
final settings = await db.get('settings');
final isDark = settings['theme'] == 'dark';// Add to cart
await db.put('cart:product-123', {
'name': 'Flutter Book',
'price': 29.99,
'quantity': 2
});
// Get cart total
final items = await db.getAll('cart:*');
double total = 0;
items.forEach((_, item) {
total += item['price'] * item['quantity'];
