### Flutter Video Player Control Panel Example

Source: https://pub.dev/packages/video_player_control_panel/versions/1.0.4/example

This Flutter Dart code demonstrates how to integrate and use the video_player_control_panel package. It initializes a VideoPlayerController, sets up a playlist of video sources (local and network), configures closed captions, and displays the control panel with options for play/pause, seeking, volume, fullscreen, and playlist navigation. It also includes platform-specific setup for Windows using video_player_win.

    //controller = VideoPlayerController.file(File("E:\\test_youtube.mp4"));
    controller = VideoPlayerController.network("https://www.sample-videos.com/video123/mp4/720/big_buck_bunny_720p_30mb.mp4");

    var captionFile = Future.value(SubRipCaptionFile(generateCaptionFileContent()));
    controller.setClosedCaptionFile(captionFile);

    controller.initialize().then((value) {
      if (!kIsWeb) controller.play();
      setState(() {});
    });
  }

  @override

### Play Playlist Simply

Source: https://pub.dev/packages/video_player_control_panel/index

This example shows a simplified way to play a playlist of videos using JkVideoPlaylistPlayer without directly managing the VideoPlayerController. It allows setting the playlist, looping behavior, and autoplay.

```dart

### Non-standard Variable Naming in Video Player Control Panel

Source: https://pub.dev/packages/video_player_control_panel/score

This snippet points out a variable `m_lastSeekTimestamp` that does not follow the standard lowerCamelCase naming convention in Dart. This is a linting issue identified during static analysis, suggesting a refactoring for better code readability and adherence to Dart style guides.

```dart
int m_lastSeekTimestamp = 0;

```

### Initialize Video from File

Source: https://pub.dev/packages/video_player_control_panel/index

This snippet shows how to initialize a VideoPlayerController using a local file path. Ensure the file path is correct and the application has the necessary permissions to access the file.

```dart
var controller = VideoPlayerController.file(File("E:\\test.mp4"));
```

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

### Initialize and Play Video from Network

Source: https://pub.dev/packages/video_player_control_panel/index

This code demonstrates how to initialize a VideoPlayerController with a network URL and play the video. It includes error handling for initialization failures and checks if the video has successfully initialized before playing.

```dart
var controller = VideoPlayerController.network("https://www.your-web.com/sample.mp4");
controller.initialize().then((value) {
  if (controller.value.isInitialized) {
    controller.play();
  } else {
    log("video file load failed");
  }
}).catchError((e) {
  log("controller.initialize() error occurs: $e");
});
```

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

### Add device_info_plus Dependency

Source: https://pub.dev/packages/video_player_control_panel/index

To use the `DeviceInfoPlugin` for checking device features, add the `device_info_plus` package to your `pubspec.yaml` file under the `dependencies` section. This ensures the package is available for use in your project.

```yaml
dependencies:
  device_info_plus:

```
