chewie

The video player for Flutter with a heart of gold.

The video_player plugin provides low-level access to video playback.

Chewie uses the video_player under the hood and wraps it in a friendly Material or Cupertino UI!

🚨 IMPORTANT!!! (READ THIS FIRST)

This library is NOT responsible for any issues caused by video_player, since it's merely a UI layer on top of it.

In other words, if you see any PlatformExceptions being thrown in your app due to video playback, they are exclusive to the video_player library.

Instead, please raise an issue related to it with the Flutter Team.

🔀 Flutter Version Compatibility

This library will at the very least make a solid effort to support the second most recent version of Flutter released. In other words, it will adopt N-1 version support at the bare minimum.

However, this cannot be guaranteed due to major changes between Flutter versions. Should that occur, future updates will be released as major or minor versions as needed.

⬇️ Installation

In your pubspec.yaml file within your Flutter Project add chewie and video_player under dependencies:

dependencies:
  chewie: <latest_version>
  video_player: <latest_version>

🕹️ Using it

import 'package:chewie/chewie.dart';
import 'package:video_player/video_player.dart';

final videoPlayerController = VideoPlayerController.networkUrl(Uri.parse(
    'https://flutter.github.io/assets-for-api-docs/assets/videos/butterfly.mp4'));

await videoPlayerController.initialize();

final chewieController = ChewieController(
  videoPlayerController: videoPlayerController,
  autoPlay: true,
  looping: true,
);

final playerWidget = Chewie(
  controller: chewieController,
);

Please make sure to dispose both controller widgets after use. For example, by overriding the dispose method of the a StatefulWidget:

@override
void dispose() {
  videoPlayerController.dispose();
  chewieController.dispose();
  super.dispose();
}

⚙️ Options

Chewie has some options which control the video. These options appear by default in a showModalBottomSheet (similar to YT). By default, Chewie passes Playback speed and Subtitles options as an OptionItem.

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

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

Customizing the modal sheet

If you don't like the default showModalBottomSheet for showing your options, you can override the View with the optionsBuilder method:

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)!

Translations

What is an option without proper translation?

To add your translation strings add:

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

🔡 Subtitles

Since version 1.1.0, Chewie supports subtitles.

Chewie allows you to enhance the video playback experience with text overlays. You can add a List<Subtitle> to your ChewieController and fully customize their appearance using the subtitleBuilder function.

Showing Subtitles by Default

Chewie provides the showSubtitles flag, allowing you to control whether subtitles are displayed automatically when the video starts. By default, this flag is set to false.

Adding Subtitles

Here’s an example of how to add subtitles to your ChewieController:

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: 'What’s up? :)',
    ),
  ]),
  showSubtitles: true, // Automatically display subtitles
  subtitleBuilder: (context, subtitle) => Container(
    padding: const EdgeInsets.all(10.0),
    child: Text(
      subtitle,
      style: const TextStyle(color: Colors.white),
    ),
  ),
);

Subtitle Structure

The Subtitle model contains the following key attributes:

• index: A unique identifier for the subtitle, useful for database integration.
• start: The starting point of the subtitle, defined as a Duration.
• end: The ending point of the subtitle, defined as a Duration.
• text: The subtitle text that will be displayed.

For example, if your video is 10 minutes long and you want to add a subtitle that appears between 00:00 and 00:10, you can define it like this:

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

Customizing Subtitles

Use the subtitleBuilder function to customize how subtitles are rendered, allowing you to modify text styles, add padding, or apply other customizations to your subtitles.

🧪 Example

Please run the app in the example/ folder to start playing!

⏪ Migrating from Chewie < 0.9.0

Instead of passing the VideoPlayerController and your options to the Chewie widget you now pass them to the ChewieController and pass that later to the Chewie widget.

final playerWidget = Chewie(
  videoPlayerController,
  autoPlay: true,
  looping: true,
);

becomes

final chewieController = ChewieController(
  videoPlayerController: videoPlayerController,
  autoPlay: true,
  looping: true,
);

final playerWidget = Chewie(
  controller: chewieController,
);
