## 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:
```shell
flutter pub add apivideo_live_stream
```
In your dart file, import the package:
```dart
import 'package:apivideo_live_stream/apivideo_live_stream.dart';
```
### Permissions
To be able to broadcast, you must:
1. On Android: ask for internet, camera and microphone permissions:
```xml
```
The library will require android.permission.CAMERA and android.permission.RECORD_AUDIO at runtime.
You don't need to request them.
2. On iOS: update the Info.plist with a usage description for camera and microphone
```xml
NSCameraUsageDescription
Your own description of the purpose
NSMicrophoneUsageDescription
Your own description of the purpose
```
### Code sample
1. Creates a live stream controller
```dart
final ApiVideoLiveStreamController _controller = ApiVideoLiveStreamController(
initialAudioConfig: AudioConfig(), initialVideoConfig: VideoConfig.withDefaultBitrate());
```
2. Initializes the live stream controller
```dart
await _controller.initialize();
```
3. Adds a CameraPreview widget as a child of your view
```dart
@override
Widget build(BuildContext context) {
return SizedBox(
width: 300.0,
height: 300.0,
child: ApiVideoCameraPreview(controller: _controller));
}
```
`ApiVideoCameraPreview` parameters:
- `controller`: the live stream controller
- `fit`: the fit of the preview (default is BoxFit.contain,
see [BoxFit](https://api.flutter.dev/flutter/painting/BoxFit.html) for more information)
- `child`: a child widget to overlay on top of the preview (optional)
4. Starts a live stream
```dart
_controller.startStreaming("YOUR_STREAM_KEY");
```
5. Stops streaming and preview
```dart
_controller.stop();
```
#### Manage application lifecycle
On the application side, you must manage application lifecycle:
```dart
@override
void didChangeAppLifecycleState(AppLifecycleState state) {
if (state == AppLifecycleState.inactive) {
_controller.stop();
} else if (state == AppLifecycleState.resumed) {
_controller.startPreview();
}
}
```
