audioplayers_watchos 0.0.1

watchOS implementation of the audioplayers plugin, playing audio through AVFoundation (AVPlayer) via dart:ffi.

audioplayers_watchos

The watchOS implementation of audioplayers.

Playback is driven by AVPlayer (AVFoundation) through dart:ffi — the supported plugin model on watchOS. One native player is kept per playerId; play/pause/seek/volume/rate/release-mode are applied natively, and the event stream (prepared, duration, seekComplete, complete, errors) is derived by polling a lock-guarded native state snapshot.

Usage

This is a federated plugin implementation. Apps that already depend on audioplayers and target watchOS only need to add this package alongside it:

dependencies:
  audioplayers: ^<latest>
  audioplayers_watchos: ^0.0.1

No other change — AudioPlayer and friends work as on the other platforms. Asset sources go through audioplayers' own AudioCache, which uses path_provider; add path_provider_watchos alongside it the same way.

watchOS notes

• Balance (setBalance) is not supported — AVPlayer has no per-channel balance. Calls emit a log event instead of throwing, matching the upstream iOS behaviour.
• Player mode (setPlayerMode) is a no-op; watchOS has no low-latency AVAudioPlayer pool.
• Audio context: the AudioContextIOS category and the mixWithOthers / duckOthers options map onto the watch AVAudioSession. iOS-only options with no watchOS equivalent (e.g. defaultToSpeaker) are ignored — the watch routes output itself (Bluetooth headphones or speaker).
• Bytes sources (setSourceBytes) are spooled to a temporary file and played from there; pass mimeType so the container format is known.
• On a real watch, background/long-form playback is subject to the system audio-session policy; short UI sounds and foreground playback behave as on iOS.

Example on the watch screen

The bundled example is the upstream audioplayers example, verbatim. It is a phone-designed multi-tab UI, so its runner sets FlutterWatchOSContentScale in Info.plist to render it scaled-to-fit on the watch. See the example README for details.
