  1. Add this to your pubspec.yaml file:
  better_player: ^0.0.44
  1. Install it
$ flutter packages get
  1. Import it
import 'package:better_player/better_player.dart';

General Usage

Check Example project which shows how to use Better Player in different scenarios.

Basic usage

There are 2 basic methods which you can use to setup Better Player:, configuration)
BetterPlayer.file(url, configuration)

There methods setup basic configuration for you and allows you to start using player in few seconds. Here is an example:

  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Example player"),
      body: AspectRatio(
        aspectRatio: 16 / 9,
          betterPlayerConfiguration: BetterPlayerConfiguration(
            aspectRatio: 16 / 9,

In this example, we’re just showing video from url with aspect ratio = 16/9. Better Player has many more configuration options which are presented below.

Normal usage

Create BetterPlayerDataSource and BetterPlayerController. You should do it in initState:

BetterPlayerController _betterPlayerController;

  void initState() {
    BetterPlayerDataSource betterPlayerDataSource = BetterPlayerDataSource(,
    _betterPlayerController = BetterPlayerController(
        betterPlayerDataSource: betterPlayerDataSource);

Create BetterPlayer widget wrapped in AspectRatio widget:

  Widget build(BuildContext context) {
    return AspectRatio(
      aspectRatio: 16 / 9,
      child: BetterPlayer(
        controller: _betterPlayerController,


To use playlist, you need to create dataset with multiple videos:

  List<BetterPlayerDataSource> createDataSet() {
    List dataSourceList = List<BetterPlayerDataSource>();
    return dataSourceList;

Then create BetterPlayerPlaylist:

  Widget build(BuildContext context) {
    return AspectRatio(
      aspectRatio: 16 / 9,
      child: BetterPlayerPlaylist(
          betterPlayerConfiguration: BetterPlayerConfiguration(),
          betterPlayerPlaylistConfiguration: const BetterPlayerPlaylistConfiguration(),
          betterPlayerDataSourceList: dataSourceList),


BetterPlayerListViewPlayer will auto play/pause video once video is visible on screen with playFraction. PlayFraction describes percent of video that must be visibile to play video. If playFraction is 0.8 then 80% of video height must be visible on screen to auto play video

  Widget build(BuildContext context) {
    return AspectRatio(
      aspectRatio: 16 / 9,
      child: BetterPlayerListVideoPlayer(
  , videoListData.videoUrl),
        key: Key(videoListData.hashCode.toString()),
        playFraction: 0.8,

You can control BetterPlayerListViewPlayer with BetterPlayerListViewPlayerController. You need to pass BetterPlayerListViewPlayerController to BetterPlayerListVideoPlayer. See more in example app.


Subtitles can be configured from 3 different sources: file, network and memory. Subtitles source is passed in BetterPlayerDataSource:

Network subtitles:

    var dataSource = BetterPlayerDataSource(,
      subtitles: BetterPlayerSubtitlesSource.single(

File subtitles:

 var dataSource = BetterPlayerDataSource(
      subtitles: BetterPlayerSubtitlesSource.single(
        type: BetterPlayerSubtitlesSourceType.file,
        url: "${directory.path}/",

You can pass multiple subtitles for one video:

var dataSource = BetterPlayerDataSource(,
      liveStream: false,
      useHlsSubtitles: true,
      hlsTrackNames: ["Low quality", "Not so low quality", "Medium quality"],
      subtitles: [
          name: "EN",
          urls: [

          name: "DE",
          urls: [


You can provide configuration to your player when creating BetterPlayerController.

    var betterPlayerConfiguration = BetterPlayerConfiguration(
      autoPlay: true,
      looping: true,
      fullScreenByDefault: true,

Possible configuration options:

    /// Play the video as soon as it's displayed
    final bool autoPlay;

    /// Start video at a certain position
    final Duration startAt;

    /// Whether or not the video should loop
    final bool looping;

    /// Weather or not to show the controls when initializing the widget.
    final bool showControlsOnInitialize;

    /// When the video playback runs  into an error, you can build a custom
    /// error message.
    final Widget Function(BuildContext context, String errorMessage) errorBuilder;

    /// The Aspect Ratio of the Video. Important to get the correct size of the
    /// video!
    /// Will fallback to fitting within the space allowed.
    final double aspectRatio;

    /// The placeholder is displayed underneath the Video before it is initialized
    /// or played.
    final Widget placeholder;

    /// Should the placeholder be shown until play is pressed
    final bool showPlaceholderUntilPlay;

    /// Placeholder position of player stack. If false, then placeholder will be
    /// displayed on the bottom, so user need to hide it manually. Default is
    /// true.
    final bool placeholderOnTop;

    /// A widget which is placed between the video and the controls
    final Widget overlay;

    /// Defines if the player will start in fullscreen when play is pressed
    final bool fullScreenByDefault;

    /// Defines if the player will sleep in fullscreen or not
    final bool allowedScreenSleep;

    /// Defines aspect ratio which will be used in fullscreen
    final double fullScreenAspectRatio;

    /// Defines the set of allowed device orientations on entering fullscreen
    final List<DeviceOrientation> deviceOrientationsOnFullScreen;

    /// Defines the system overlays visible after exiting fullscreen
    final List<SystemUiOverlay> systemOverlaysAfterFullScreen;

    /// Defines the set of allowed device orientations after exiting fullscreen
    final List<DeviceOrientation> deviceOrientationsAfterFullScreen;

    /// Defines a custom RoutePageBuilder for the fullscreen
    final BetterPlayerRoutePageBuilder routePageBuilder;

    /// Defines a event listener where video player events will be send
    final Function(BetterPlayerEvent) eventListener;

    ///Defines subtitles configuration
    final BetterPlayerSubtitlesConfiguration subtitlesConfiguration;

    ///Defines controls configuration
    final BetterPlayerControlsConfiguration controlsConfiguration;

    ///Defines fit of the video, allows to fix video stretching, see possible
    ///values here:
    final BoxFit fit;

    ///Defines rotation of the video in degrees. Default value is 0\. Can be 0, 90, 180, 270.
    ///Angle will rotate only video box, controls will be in the same place.
    final double rotation;

    ///Defines function which will react on player visibility changed
    final Function(double visibilityFraction) playerVisibilityChangedBehavior;

    ///Defines translations used in player. If null, then default english translations
    ///will be used.
    final List<BetterPlayerTranslations> translations;

    ///Defines if player should auto detect full screen device orientation based
    ///on aspect ratio of the video. If aspect ratio of the video is < 1 then
    ///video will played in full screen in portrait mode. If aspect ratio is >= 1
    ///then video will be played horizontally. If this parameter is true, then
    ///[deviceOrientationsOnFullScreen] and [fullScreenAspectRatio] value will be
    /// ignored.
    final bool autoDetectFullscreenDeviceOrientation;

    ///Defines flag which enables/disables lifecycle handling (pause on app closed,
    ///play on app resumed). Default value is true.
    final bool handleLifecycle;

    ///Defines flag which enabled/disabled auto dispose on BetterPlayer dispose.
    ///Default value is true.
    final bool autoDispose;


You can provide subtitles configuration with this class. You should put BetterPlayerSubtitlesConfiguration in BetterPlayerConfiguration.

 var betterPlayerConfiguration = BetterPlayerConfiguration(
      subtitlesConfiguration: BetterPlayerSubtitlesConfiguration(
        fontSize: 20,

Possible configuration options:

 ///Subtitle font size
  final double fontSize;

  ///Subtitle font color
  final Color fontColor;

  ///Right padding of the subtitle
  final double rightPadding;

  ///Bottom padding of the subtitle
  final double bottomPadding;

  ///Alignment of the subtitle
  final Alignment alignment;

  ///Background color of the subtitle
  final Color backgroundColor;

  ///Subtitles selected by default, without user interaction
  final bool selectedByDefault;


Configuration for player GUI. You should pass this configuration to BetterPlayerConfiguration.

var betterPlayerConfiguration = BetterPlayerConfiguration(
      controlsConfiguration: BetterPlayerControlsConfiguration(
   ///Color of the control bars
   final Color controlBarColor;

   ///Color of texts
   final Color textColor;

   final bool enableOverflowMenu;

   ///Flag used to show/hide playback speed
   final bool enablePlaybackSpeed;

   ///Flag used to show/hide subtitles
   final bool enableSubtitles;

   ///Flag used to show/hide qualities
   final bool enableQualities;

   ///Custom items of overflow menu
   final List<BetterPlayerOverflowMenuItem> overflowMenuCustomItems;

Configure your playlist. Pass this object to BetterPlayerPlaylist

 var betterPlayerPlaylistConfiguration = BetterPlayerPlaylistConfiguration(
      loopVideos: false,
      nextVideoDelay: Duration(milliseconds: 5000),

Possible configuration options:

  ///How long user should wait for next video
  final Duration nextVideoDelay;

  ///Should videos be looped
  final bool loopVideos;


Define source for one video in your app. There are 3 types of data sources:

  • Network - data source which uses url to play video from external resources
  • File - data source which uses url to play video from internal resources
  • Memory - data source which uses list of bytes to play video from memory
    var dataSource = BetterPlayerDataSource(,
      subtitles: BetterPlayerSubtitlesSource(
        type: BetterPlayerSubtitlesSourceType.file,
        url: "${directory.path}/",
      headers: {"header":"my_custom_header"}

You can use type specific factories to build your data source. Use to build network data source, BetterPlayerDataSource.file to build file data source and BetterPlayerDataSource.memory to build memory data source.

Possible configuration options:

  ///Type of source of video
  final BetterPlayerDataSourceType type;

  ///Url of the video
  final String url;

  ///Subtitles configuration
  ///You can pass here multiple subtitles
  final List<BetterPlayerSubtitlesSource> subtitles;

  ///Flag to determine if current data source is live stream
  final bool liveStream;

  /// Custom headers for player
  final Map<String, String> headers;

  ///Should player use hls subtitles. Default is true.
  final bool useHlsSubtitles;

  ///Should player use hls tracks
  final bool useHlsTracks;

  ///List of strings that represents tracks names.
  ///If empty, then better player will choose name based on track parameters
  final List<String> hlsTrackNames;

  ///Optional, alternative resolutions for non-hls video. Used to setup
  ///different qualities for video.
  ///Data should be in given format:
  ///{"360p": "url", "540p": "url2" }
  final Map<String, String> resolutions;

  ///Optional cache configuration, used only for network data sources
  final BetterPlayerCacheConfiguration cacheConfiguration;


Define cache configuration for given data source. Cache works only for network data sources.

  ///Enable cache for network data source
  final bool useCache;

  /// The maximum cache size to keep on disk in bytes.
  /// Android only option.
  final int maxCacheSize;

  /// The maximum size of each individual file in bytes.
  /// Android only option.
  final int maxCacheFileSize;


Define source of subtitles in your video:

 var subtitles = BetterPlayerSubtitlesSource(
        type: BetterPlayerSubtitlesSourceType.file,
        url: "${directory.path}/",

Possible configuration options:

  ///Source type
  final BetterPlayerSubtitlesSourceType type;

  ///Url of the subtitles, used with file or network subtitles
  final String url;

  ///Content of subtitles, used when type is memory
  final String content;


You can provide translations for different languages. You need to pass list of BetterPlayerTranslations to the BetterPlayerConfiguration. Here is an example:

 translations: [
                languageCode: "language_code for example pl",
                generalDefaultError: "translated text",
                generalNone: "translated text",
                generalDefault: "translated text",
                playlistLoadingNextVideo: "translated text",
                controlsLive: "translated text",
                controlsNextVideoIn: "translated text",
                overflowMenuPlaybackSpeed: "translated text",
                overflowMenuSubtitles: "translated text",
                overflowMenuQuality: "translated text",
                languageCode: "other language for example cz",
                generalDefaultError: "translated text",
                generalNone: "translated text",
                generalDefault: "translated text",
                playlistLoadingNextVideo: "translated text",
                controlsLive: "translated text",
                controlsNextVideoIn: "translated text",
                overflowMenuPlaybackSpeed: "translated text",
                overflowMenuSubtitles: "translated text",
                overflowMenuQuality: "translated text",

There are 4 pre build in languages: EN, PL, ZH (chinese simplified), HI (hindi). If you didn’t provide any translation then EN translations will be used or any of the pre build in translations, only if it’s match current user locale.

You need to setup localizations in your app first to make it work. Here’s how you can do that:

Listen to video events

You can listen to video player events like:


After creating BetterPlayerController you can add event listener this way:

      print("Better player event: ${event.betterPlayerEventType}");

Your event listener will ne auto-disposed on dispose time :)

Change player behavior if player is not visible

You can change player behavior if player is not visible by using playerVisibilityChangedBehavior option in BetterPlayerConfiguration. Here is an example for player used in list:

 void onVisibilityChanged(double visibleFraction) async {
    bool isPlaying = await _betterPlayerController.isPlaying();
    bool initialized = _betterPlayerController.isVideoInitialized();
    if (visibleFraction >= widget.playFraction) {
      if (widget.autoPlay && initialized && !isPlaying && !_isDisposing) {;
    } else {
      if (widget.autoPause && initialized && isPlaying && !_isDisposing) {

Player behavior works in the basis of VisibilityDetector (it uses visibilityFraction, which is value from 0.0 to 1.0 that describes how much given widget is on the viewport). So if value 0.0, player is not visible, so we need to pause the video. If the visibilityFraction is 1.0, we need to play it again.

Pass multiple resolutions of the video

You can setup video with different resolutions. Use resolutions parameter in data source. This should be used only for normal videos (non-hls) to setup different qualities of the original video.

    var dataSource = BetterPlayerDataSource(,
        resolutions: {

Setup player notification

| | | |

To setup player notification use notificationConfiguration in BetterPlayerDataSource.

BetterPlayerDataSource dataSource = BetterPlayerDataSource(,
      notificationConfiguration: BetterPlayerNotificationConfiguration(
        showNotification: true,
        title: "Elephant dream",
        author: "Some author",

There are 3 majors parameters here: title - name of the resource, shown in first line author - author of the resource, shown in second line imageUrl - image of the resource (optional). Can be both link to external image or internal file.

If showNotification is set as true and no title and author is provided, then empty notification will be displayed.

User can control the player with notification buttons (i.e. play/pause, seek). When notification feature is used when there are more players at the same time, then last player will be used. Notification will be shown after play for the first time.

To play resource after leaving the app, set handleLifecycle as false in your BetterPlayerConfiguration.

Important note for android: You need to add special service in android native code. Service will simply destroy all remaining notifications. This service need to be used to handle situation when app is killed without proper player destroying. Check BetterPlayerService in example project to see how to add this service to your app.

Here is an example of player with notification:

Add custom element to overflow menu

You can use BetterPlayerControlsConfiguration to add custom element to the overflow menu:

  controlsConfiguration: BetterPlayerControlsConfiguration(
              overflowMenuCustomItems: [
                  "Custom element",
                  () => print("Click!"),

Enable/disable controls (always hidden if false)


Set overridden aspect ratio. If passed overriddenAspectRatio will be used instead of aspectRatio.

If null then aspectRatio from BetterPlayerConfiguration will be used.


Overridden duration

If overridden duration is set then video player will play video until this duration.

BetterPlayerDataSource dataSource = BetterPlayerDataSource(,
      ///Play only 10 seconds of this video.
      overriddenDuration: Duration(seconds: 10),

(iOS only) Add into info.plist (to support fullscreen rotation):
