The audio player for Flutter with a heart of gold.

The [`video_player`](https://pub.dartlang.org/packages/video_player) plugin provides low-level access to video/audio playback. Chewie Audio uses the `video_player` under the hood and wraps it in a friendly Material or Cupertino UI!

## Preview

### MaterialControls

### CupertinoControls

![](https://github.com/Sub6Resources/chewie_audio/raw/master/assets/CupertinoControls.png)

## Installation

In your `pubspec.yaml` file within your Flutter Project:

```yaml
dependencies:
  chewie_audio: <latest_version>
  video_player: <latest_version>
```

## Use it

```dart
import 'package:chewie_audio/chewie_audio.dart';
final videoPlayerController = VideoPlayerController.network(
    'https://flutter.github.io/assets-for-api-docs/assets/videos/butterfly.mp4');

await videoPlayerController.initialize();

final chewieAudioController = ChewieAudioController(
  videoPlayerController: videoPlayerController,
  autoPlay: true,
  looping: true,
);

final playerWidget = ChewieAudio(
  controller: chewieAudioController,
);
```

Please make sure to dispose both controller widgets after use. For example by overriding the dispose method of the a `StatefulWidget`:
```dart
@override
void dispose() {
  videoPlayerController.dispose();
  chewieAudioController.dispose();
  super.dispose();
}
```

## Options

Chewie got some options which controls the video you provide. These options appear on default on a `showModalBottomSheet` (like you already know from YT maybe). Chewie is passing on default `Playback speed` and `Subtitles` options as an `OptionItem`.

To add additional options just add these lines to your `ChewieController`:

```dart
additionalOptions: (context) {
  return <OptionItem>[
    OptionItem(
      onTap: () => debugPrint('My option works!'),
      iconData: Icons.chat,
      title: 'My localized title',
    ),
    OptionItem(
      onTap: () =>
          debugPrint('Another option working!'),
      iconData: Icons.chat,
      title: 'Another localized title',
    ),
  ];
},
```

If you don't like to show your options with the default `showModalBottomSheet` just override the View with the `optionsBuilder` method:

```dart
optionsBuilder: (context, defaultOptions) async {
  await showDialog<void>(
    context: context,
    builder: (ctx) {
      return AlertDialog(
        content: ListView.builder(
          itemCount: defaultOptions.length,
          itemBuilder: (_, i) => ActionChip(
            label: Text(defaultOptions[i].title),
            onPressed: () =>
                defaultOptions[i].onTap!(),
          ),
        ),
      );
    },
  );
},
```

Your `additionalOptions` are already included here (if you provided `additionalOptions`)!

Last but not least: What is an option without proper translation. To add your strings to them just add:

```dart
optionsTranslation: OptionsTranslation(
  playbackSpeedButtonText: 'Wiedergabegeschwindigkeit',
  subtitlesButtonText: 'Untertitel',
  cancelButtonText: 'Abbrechen',
),
```

## Subtitles

> Since version 1.1.0 chewie supports subtitles. Here you can see how to use them

You can provide an `List<Subtitle>` and customize your subtitles with the `subtitleBuilder` function.

Just add subtitles as following code is showing into your `ChewieController`:

```dart
ChewieController(
  videoPlayerController: _videoPlayerController,
  autoPlay: true,
  looping: true,
  subtitle: Subtitles([
    Subtitle(
      index: 0,
      start: Duration.zero,
      end: const Duration(seconds: 10),
      text: 'Hello from subtitles',
    ),
    Subtitle(
      index: 1,
      start: const Duration(seconds: 10),
      end: const Duration(seconds: 20),
      text: 'Whats up? :)',
    ),
  ]),
  subtitleBuilder: (context, subtitle) => Container(
    padding: const EdgeInsets.all(10.0),
    child: Text(
      subtitle,
      style: const TextStyle(color: Colors.white),
    ),
  ),
);
```

The `index` attribute is just for purpases if you want to structure your subtitles in your database and provide your indexes here. `start`, `end` and `text` are here the key attributes.

The Duration defines on which part of your video your subtitles should start and end. For example: Your video is 10 minutes long and you want to add a subtitle between: `00:00` and `00:10`'th second you've to provide:

```dart
Subtitle(
  index: 0,
  start: Duration.zero,
  end: const Duration(seconds: 10),
  text: 'Hello from subtitles',
),
```

## Example

Please run the app in the [`example/`](https://github.com/Sub6Resources/chewie_audio/tree/master/example) folder to start playing!
