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!

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>
copied to clipboard
Using it #
import 'package:chewie/chewie.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,
);
copied to clipboard
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',
),
];
},
copied to clipboard
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!(),
),
),
);
},
);
},
copied to clipboard
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',
),
copied to clipboard
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.
Add subtitles to your ChewieController like the following example:
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),
),
),
);
copied to clipboard
The index attribute is for if you want to structure your subtitles in your database and provide your indexes here. end and text are the key attributes.
The Duration defines which part of your video your subtitles should start and end. For example, if your video is 10 minutes long and you want to add a subtitle between: 00:00 and 00:10'th of a second:
Subtitle(
index: 0,
start: Duration.zero,
end: const Duration(seconds: 10),
text: 'Hello from 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,
);
copied to clipboard
becomes
final chewieController = ChewieController(
videoPlayerController: videoPlayerController,
autoPlay: true,
looping: true,
);

final playerWidget = Chewie(
controller: chewieController,
);
