### Installing live_file_publisher Package

Source: https://github.com/sxudan/live_file_publisher/blob/main/README.md

This snippet demonstrates how to add the `live_file_publisher` package to a Flutter project using the `flutter pub add` command, which automatically updates the `pubspec.yaml` file with the package dependency.

```Shell
flutter pub add live_file_publisher
```

### Connecting and Publishing Stream with LiveFilePublisher in Dart

Source: https://github.com/sxudan/live_file_publisher/blob/main/README.md

This code demonstrates how to establish a connection to a streaming server using a specified URL and protocol, and then initiate the publishing of a video file with a given start time, file path, and stream name.

```Dart
filePublisher.connect(url: 'rtsp://localhost', mode: PublisherProtocol.RTSP_UDP);
filePublisher.publish(startTime: '00:00:00',filePath: <filepath>,name: 'mystream');
```

### Importing and Initializing LiveFilePublisher in Dart

Source: https://github.com/sxudan/live_file_publisher/blob/main/README.md

This code imports the `live_file_publisher` package and initializes an instance of `LiveFilePublisher`, which is the primary class for managing video file publishing operations within a Flutter application.

```Dart
import 'package:live_file_publisher/live_file_publisher.dart';

LiveFilePublisher filePublisher = LiveFilePublisher();
```

### Setting Up Event Listeners for LiveFilePublisher in Dart

Source: https://github.com/sxudan/live_file_publisher/blob/main/README.md

This snippet shows how to register state, error, and log listeners within a Flutter `initState` method. These callbacks allow the application to react to publishing events, errors, and receive diagnostic logs from the `LiveFilePublisher` instance.

```Dart
@override
void initState() {
  super.initState();
  filePublisher.addStateListener(onStateListener);
  filePublisher.addErrorListener(onErrorListener);
  filePublisher.addLogListener(onLogListener);
}
```

--------------------------------

### Implementing LiveFilePublisher Event Callbacks in Dart

Source: https://github.com/sxudan/live_file_publisher/blob/main/README.md

These functions define the callback logic for handling publishing state changes, errors, and log messages from the `LiveFilePublisher`. They demonstrate basic printing of the received data for debugging or monitoring purposes.

```Dart
void onStateListener(PublishingState state) {
  print(state);
}

void onErrorListener(Object error) {
  print(error);
}

void onLogListener(String log) {
  print(log)
}
```

### Defining PublisherProtocol Enum in Dart

Source: https://github.com/sxudan/live_file_publisher/blob/main/README.md

This enum defines the supported streaming protocols for the `live_file_publisher` package, including RTMP, RTSP over UDP, and RTSP over TCP, allowing users to specify the desired connection mode.

```Dart
enum PublisherProtocol {
  RTMP,
  RTSP_UDP,
  RTSP_TCP,
}
```

--------------------------------

### Defining PublishingState Enum in Dart

Source: https://github.com/sxudan/live_file_publisher/blob/main/README.md

This enum represents the various states of the publishing process within the `live_file_publisher` package, such as normal operation, request to publish, actively publishing, and request to stop publishing.

```Dart
enum PublishingState {
  Normal,
  RequestPublish,
  Publishing,
  RequestStopPublish,
}
```

--------------------------------

### Stopping LiveFilePublisher Stream in Dart

Source: https://github.com/sxudan/live_file_publisher/blob/main/README.md

This snippet shows the simple method call to stop the ongoing video publishing operation initiated by the `LiveFilePublisher` instance, terminating the stream to the server.

```Dart
filePublisher.stop();
```
