📦 Install

Add to pubspec.yaml:

dependencies:
  tha_player: ^0.5.1

Then:

flutter pub get

🚀 Quick Start

import 'package:tha_player/tha_player.dart';

final ctrl = ThaNativePlayerController.single(
  ThaMediaSource(
    'https://storage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4',
    // Optional VTT thumbnails
    // thumbnailVttUrl: 'https://example.com/thumbs.vtt',
  ),
  autoPlay: true,
  playbackOptions: ThaPlaybackOptions(
    maxRetryCount: 5,
    initialRetryDelay: Duration(milliseconds: 800),
  ),
  initialPreferences: const ThaPlayerPreferences(
    playbackSpeed: 1.0,
    dataSaver: false,
  ),
);

// In build:
AspectRatio(
  aspectRatio: 16 / 9,
  child: ThaModernPlayer(
    controller: ctrl,
    doubleTapSeek: Duration(seconds: 10),
    longPressSeek: Duration(seconds: 3),
    autoHideAfter: Duration(seconds: 3),
    initialBoxFit: BoxFit.contain,
    onErrorDetails: (err) {
      if (err != null) {
        debugPrint('Playback error: ${err.code} • ${err.message}');
      }
    },
  ),
)

Migration to 0.5.0

1. Preferences now live on the controller (ctrl.preferences) and persist across fullscreen.
2. Use ctrl.playbackState instead of listening directly to platform events.
3. Prefer onErrorDetails / ctrl.errorDetails for structured failures (string onError still works).

Fullscreen

Tap the fullscreen icon in the control bar. Playback state, BoxFit, and preferences are preserved when entering/exiting fullscreen.

BoxFit

Choose between contain, cover, fill, fitWidth, and fitHeight from the menu. BoxFit is shared via the controller by default.

Track Selection

Use the control bar to switch quality, audio, or subtitle tracks at runtime. You can also fetch tracks directly:

final qualities = await ctrl.getVideoTracks();
final audios = await ctrl.getAudioTracks();
final subtitles = await ctrl.getSubtitleTracks();
await ctrl.selectAudioTrack(audios.first.id);
await ctrl.selectSubtitleTrack(null); // disable captions

Playback State

Listen to the controller’s playback state without reaching into the event channel:

ValueListenableBuilder<ThaPlaybackState>(
  valueListenable: ctrl.playbackState,
  builder: (_, state, __) => Text(
    '${state.position.inSeconds}s / ${state.duration.inSeconds}s',
  ),
)

Preferences

Preferences live on the controller so fullscreen swaps preserve your choices:

await ctrl.setSpeed(1.5); // persists
await ctrl.setDataSaver(true);
await ctrl.selectAudioTrack(null); // reset to default

You can also inspect the current preference snapshot via ctrl.preferences.value, or reset to the initial defaults:

ctrl.resetPreferences();

Lock Controls

Use the lock icon to prevent controls/gestures; unlock with the floating button.

DRM (Android)

final ctrl = ThaNativePlayerController.single(
  ThaMediaSource(
    'https://my.cdn.com/drm/manifest.mpd',
    drm: ThaDrmConfig(
      type: ThaDrmType.widevine, // or ThaDrmType.clearKey
      licenseUrl: 'https://license.server/wv',
      headers: {'Authorization': 'Bearer <token>'},
      // clearKey: '{"keys":[{"kty":"oct","k":"...","kid":"..."}]}'
    ),
  ),
);

Thumbnails (WebVTT)

Provide a .vtt with sprites or images and optional #xywh regions:

ThaMediaSource(
  'https://example.com/video.m3u8',
  thumbnailVttUrl: 'https://example.com/thumbs.vtt',
)

🛠 Platform Notes

• Android: ExoPlayer backend with Media3; Widevine/ClearKey supported; per‑item HTTP headers.
• iOS: AVPlayer backend; fitWidth/fitHeight approximate via resizeAspect.
• Keep‑screen‑on is enabled during playback (Android/iOS).
• Playability depends on device codecs, stream, and network.

Thumbnails are cached in-memory. Call clearThumbnailCache() if you need to purge the cache.

Resilient playback

ThaPlaybackOptions lets you tweak retry/backoff behaviour and rebuffer handling. Failures are surfaced via ThaNativeEvents.error for legacy use, plus ThaPlayerError through ctrl.errorDetails or onErrorDetails on ThaModernPlayer.

Custom HTTP (Android)

Provide a bespoke OkHttpClient to inject interceptors or caching:

Register the factory inside your Android Application:

class App : FlutterApplication() {
  override fun onCreate() {
    super.onCreate()
    ThaPlayerPlugin.setHttpClientFactory {
      OkHttpClient.Builder()
        .addInterceptor(MyHeaderInterceptor())
        .cache(Cache(cacheDir.resolve("video"), 100L * 1024L * 1024L))
        .build()
    }
  }
}

Set the factory before creating any Flutter controllers so every instance shares the same client.

16 KB Page Size Support

This plugin does not ship custom native decoder binaries. If you add native libraries, link them with a max page size compatible with 16 KB systems (e.g., -Wl,-z,max-page-size=16384 on Android NDK).

🧪 Example

See example/ for a runnable app that demonstrates the modern controls, gestures, fullscreen, and thumbnails.
