Project description #
This module is made for broadcasting RTMP live stream from smartphone camera.
Getting started #
Installation #
Run the following command at the root of your project:
flutter pub add apivideo_live_stream
copied to clipboard
In your dart file, import the package:
import 'package:apivideo_live_stream/apivideo_live_stream.dart';
copied to clipboard
Permissions #
To be able to broadcast, you must:

On Android: ask for internet, camera and microphone permissions:

<manifest>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAMERA" />
</manifest>
copied to clipboard
The library will require android.permission.CAMERA and android.permission.RECORD_AUDIO at runtime.
You don't need to request them.

On iOS: update the Info.plist with a usage description for camera and microphone

<key>NSCameraUsageDescription</key>
<string>Your own description of the purpose</string>
<key>NSMicrophoneUsageDescription</key>
<string>Your own description of the purpose</string>

Code sample #

Creates a live stream controller

final ApiVideoLiveStreamController _controller = ApiVideoLiveStreamController(
initialAudioConfig: AudioConfig(), initialVideoConfig: VideoConfig.withDefaultBitrate());

await _controller.initialize();
copied to clipboard

Adds a CameraPreview widget as a child of your view

@override
Widget build(BuildContext context) {
return SizedBox(
width: 300.0,
height: 300.0,
child: ApiVideoCameraPreview(controller: _controller));
}
copied to clipboard
ApiVideoCameraPreview parameters:

controller: the live stream controller
fit: the fit of the preview (default is BoxFit.contain,

_controller.startStreaming("YOUR_STREAM_KEY");
copied to clipboard

Stops streaming and preview

_controller.stop();
copied to clipboard
Manage application lifecycle
On the application side, you must manage application lifecycle:
@override
void didChangeAppLifecycleState(AppLifecycleState state) {
if (state == AppLifecycleState.inactive) {
_controller.stop();
} else if (state == AppLifecycleState.resumed) {
_controller.startPreview();
}
}
