Real time database plugins in Flutter
1 ) Firebase Realtime Database with FlutterFire UI
Firebase Realtime Database is a cloud hosted NoSQL database storing JSON data synchronized in real time across all clients.
FlutterFire UI provides convenient widgets such as `FirebaseDatabaseListView` that enable infinite scrolling lists directly linked to Realtime Database queries.
To start, developers install the `firebase_database` and `flutterfire_ui` plugins, initialize Firebase in their `main.dart`, and then use FirebaseDatabase queries with Flutter widgets.
This integration makes it simple to build real time applications that automatically update the UI as the database changes, supporting rich interactions and offline capabilities.
2 ) Backendless Real Time Database for Flutter
Backendless offers a real time database solution compatible with Flutter (including Flutter Web), enabling apps to receive live updates on data table changes.
This service allows subscribing to database events such as new records, updates, and deletions, which reflect immediately in the app UI without manual refresh.
A quickstart involves creating data tables, importing CSV files or using REST API calls to populate sample data, and building Flutter apps that listen for updates dynamically.
Backendless real time syncing helps developers create responsive apps like dynamic movie lists or chat applications with minimal backend coding.
3 ) RxDB Reactive Local Database for Flutter
RxDB is a NoSQL local first database designed for reactive programming paradigms, compatible with Flutter through JavaScript interoperability.
It supports real time data synchronization, encryption, compression, and works well for offline first applications requiring local storage with sync capabilities.
RxDB empowers Flutter apps with responsiveness and scalability by enabling local data queries with automatic UI updates on data changes.
Developers benefit from RxDB’s capabilities for building high performance mobile apps that handle complex real time data flows and seamless syncing with backend systems.
Summary:
Flutter developers have several robust options for integrating real time databases into their applications. Firebase Realtime Database with FlutterFire UI is widely used for cloud hosted real time data sync with native Flutter widgets. Backendless provides a real time database service with easy setup and live data updates including Flutter Web support. RxDB offers a reactive local database optimized for offline first and real time syncing scenarios, expanding developers’ choices beyond cloud only solutions. Selecting the appropriate plugin depends on app requirements like local vs. cloud persistence, offline capability, and integration complexity.
