Background audio (Spotify) stops after speech_to_text stops ONLY when using bluetooth headphones

[masonjeffreys]

I am trying to get speech_to_text to work while Spotify is playing in the background.

Current Behavior

1. Spotify playing over bluetooth headphones
2. Start speech_to_text listening
3. Spotify is ducked (decreases in quality) while speech_to_text listens (this is acceptable)
4. After speech_to_text is done listening, Spotify stops entirely.

Expected Behavior
4. After speech_to_text is done listening, Spotify continues playing at the original quality.

I'm using the audio_session plugin to try different settings, but none has given me the desired result. Interestingly, if I am not using bluetooth headphones, the expected behavior is realized.

Current audio_session settings:
await session.configure(AudioSessionConfiguration( avAudioSessionCategory: AVAudioSessionCategory.playAndRecord, avAudioSessionCategoryOptions: AVAudioSessionCategoryOptions.mixWithOthers | AVAudioSessionCategoryOptions.allowBluetooth | AVAudioSessionCategoryOptions.allowBluetoothA2dp, avAudioSessionMode: AVAudioSessionMode.spokenAudio, avAudioSessionRouteSharingPolicy: AVAudioSessionRouteSharingPolicy.defaultPolicy, avAudioSessionSetActiveOptions: AVAudioSessionSetActiveOptions.none, androidAudioAttributes: const AndroidAudioAttributes( contentType: AndroidAudioContentType.speech, flags: AndroidAudioFlags.none, usage: AndroidAudioUsage.voiceCommunication, ), androidAudioFocusGainType: AndroidAudioFocusGainType.gain, androidWillPauseWhenDucked: true, ));

Looks like this is only on Android? Have you tried it on iOS?
