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!

In your pubspec.yaml
file within your Flutter Project:
dependencies:
chewie: <latest_version>
video_player: <latest_version>
import 'package:chewie/chewie.dart';
final videoPlayerController = VideoPlayerController.network(
'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();
}
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
:
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:
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:
optionsTranslation: OptionsTranslation(
playbackSpeedButtonText: 'Wiedergabegeschwindigkeit',
subtitlesButtonText: 'Untertitel',
cancelButtonText: 'Abbrechen',
),
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
:
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:
Subtitle(
index: 0,
start: Duration.zero,
end: const Duration(seconds: 10),
text: 'Hello from subtitles',
),
Please run the app in the example/
folder to start playing!
Instead of passing the VideoPlayerController
and your options to the Chewie
widget you now pass them to the ChewieController
and pass that latter 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,
);
The video_player plugin used by chewie will only work in iOS simulators if you are on flutter 1.26.0 or above. You may need to switch to the beta channel flutter channel beta
