# 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:

```dart
// Annotate a Dart class to create a Box
@Entity()
class Person {
  @Id()
  int id;
  String firstName;
  String lastName;

  Person({this.id = 0, required this.firstName, required this.lastName});
}

final Store store = await openStore(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);      // Delete

final query = box           // Query
    .query(Person_.firstName.equals('Joe') & Person_.lastName.startsWith('B'))
    .build();
final List<Person> people = query.find();
query.close();
```
