Realm Flutter

Why use Realm Flutter?

Fast, lightweight, and scalable

Realm’s live objects are integrated with StatefulWidgets and Streams, so you can build data rich apps without creating lag or draining device resources. The rich, expressive, and powerful query engine makes creating production-grade apps a breeze.

Intuitive objects that save time

No need for SQL, nor an ORM – working with your data is just like working with Flutter’s declarative UI components to get you up and running, fast. Realm’s Flutter integration automatically updates your views so you don’t have to.

Built-in mobile to cloud sync and across devices

Real-time mobile to cloud data sync makes it easy to build interactive features that keep data up-to-date across multiple devices, users, and the backend. Platform independence for a simplified, single data layer that can be shared across all your apps.

What does storing and querying data in Realm look like?

Work with intuitive APIs

Idiomatic APIs and powerful queries help you get to market faster with less code.

@RealmModel() // Create your model `_Car` like a regular Dart class
class _Car {
  late String make;
  late String model;
  int? kilometers = 500;
}

Build reactive apps with live objects

Realm’s live objects mean data updated anywhere is automatically updated everywhere.

@RealmModel() // Create your model `_Car` like a regular Dart class
class _Car {
  late String make;
  late String model;
  int? kilometers = 500;
}

Enjoy automatic data updates through Flutter Streams

Realm’s direct integration with Flutter StatefulWidgets and Streams automatically handles updates.

//Open Realm and add a car to the Realm
var config = Configuration([Car.schema]);
var realm = Realm(config);

var car = Car("Tesla", "Model Y", kilometers: 5);
realm.write(() {
  realm.add(car);
});

//Query objects in Realm
var cars = realm.all<Car>();
Car myCar = cars[0];
print("My car is ${myCar.make} model ${myCar.model}");

cars = realm.all<Car>().query("make == 'Tesla'");
