Live streaming has become an integral part of modern applications, enabling real-time communication and engagement. Flutter, Google's UI toolkit for building natively compiled applications for mobile, web, and desktop from a single codebase, provides a seamless environment for creating cross-platform applications. In this article, we will explore how to integrate the Agora SDK into a Flutter application for live streaming.
Agora SDK is a powerful and flexible platform that enables developers to integrate real-time communication features into their applications. It supports audio, video, and interactive broadcasting, making it an excellent choice for building live-streaming applications.
Prerequisites: Before we dive into the integration process, make sure you have the following:
Setting up Agora Project:
Integrating Agora SDK in Flutter
Open your Flutter project, and add the Agora Flutter SDK to your `pubspec.yaml` file:
|
dependencies: agora_rtc_engine: ^3.1.3 |
Run `flutter packages get` to install the dependency.
Now, let's initialize Agora in your Flutter app. Add the following code to your Dart file (e.g., `main.dart`):
|
import 'package:flutter/material.dart'; import 'package:agora_rtc_engine/rtc_engine.dart'; import 'package:agora_rtc_engine/rtc_local_view.dart' as RtcLocalView; import 'package:agora_rtc_engine/rtc_remote_view.dart' as RtcRemoteView; void main() => runApp(MyApp()); class MyApp extends StatefulWidget { @override _MyAppState createState() => _MyAppState(); } class _MyAppState extends State<MyApp> { final _channelController = TextEditingController(); bool _joined = false; int _remoteUid = 0; @override void dispose() { // Dispose of the controller when the widget is disposed. _channelController.dispose(); super.dispose(); } @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( appBar: AppBar( title: Text('Agora Flutter SDK'), ), body: Center( child: Column( children: <Widget>[ TextField( controller: _channelController, decoration: InputDecoration(labelText: 'Channel Name'), ), ElevatedButton( onPressed: _joinChannel, child: Text('Join Channel'), ), _joined ? _videoView() : Container(), ], ), ), ), ); } Widget _videoView() { return Expanded( child: Container( child: Stack( children: <Widget>[ RtcLocalView.SurfaceView(), _remoteVideoView(), ], ), ), ); } Widget _remoteVideoView() { if (_remoteUid != 0) { return Container( child: RtcRemoteView.SurfaceView(uid: _remoteUid), ); } else { return Container(); } } void _joinChannel() async { // Add your Agora App ID here const appId = 'YOUR_APP_ID'; if (_channelController.text.isEmpty) { return; } try { await RtcEngine.create(appId); await RtcEngine.joinChannel(null, _channelController.text, null, 0); RtcEngine.onUserJoined = (int uid, int elapsed) { setState(() { _remoteUid = uid; }); }; setState(() { _joined = true; }); } catch (e) { print(e); } } } |
Make sure to replace `'YOUR_APP_ID'` with your actual Agora App ID.
Integrating the Agora SDK into your Flutter application for live streaming is a straightforward process. With just a few steps, you can enable real-time communication features, allowing you to build engaging and interactive applications. Experiment with the code, explore additional Agora SDK functionalities, and create compelling live-streaming experiences for your users. Happy coding!
