acs_flutter_sdk

• Feature — dynamic audio-output API: the calling client can now switch the in-call audio output at runtime via setAudioRoute(AudioOutput target), read the current output with getAudioRoute(), and list selectable outputs with getAvailableAudioOutputs(). The new AudioOutput enum covers auto, speaker, earpiece, bluetooth, and wiredHeadset. auto (the default) keeps the existing behaviour — built-in loudspeaker, switching to a connected external device — while an explicit value is honoured until changed or reset to auto; if a selected external device disconnects, routing reverts to automatic. Implemented natively on Android (AudioManager) and iOS (AVAudioSession) with unit-tested routing logic.

• Fix — release renderers before detaching the call channel: when a call screen closes, the SDK now asks the native side to tear down every video renderer and release the render manager before the method-call handler is detached, dispatched while the channel is still live. This prevents leaked renderers / a teardown crash when leaving a multi-participant call.
• Feature — in-call audio output routing: in-call audio is now routed to the device's built-in loudspeaker by default, and automatically to an external output device (Bluetooth, wired headset/headphones, USB, or hearing aid) whenever one is connected. Implemented natively on both Android and iOS with unit-tested routing logic.

• iOS — fix video-call freeze on iOS 26: Remote video renderer teardown no longer blocks the platform/UI thread. The view is detached synchronously while the underlying renderer's decoder-session disposal is deferred to the next main-runloop turn, so it no longer re-enters the in-flight platform-view dispose handshake. This removes a main-thread stall that froze the app on any action during a multi-participant call on iOS 26 (reproduced on both simulator and device) and stopped the associated memory growth from undisposed decoder sessions. iOS 18 was unaffected by the original behaviour. The renderer teardown stays on the main thread, preserving the SDK's main-thread renderer affinity.

• Screen sharing: Render incoming screen-share streams in the participant grid, with dedicated handling so a shared screen and camera feeds display together.
• Multi-participant video stability: Reworked remote video rendering to track each participant's renderer independently, preventing frozen or blank tiles when participants join, leave, or toggle their camera.
• iOS: Added a native exception guard around local video stream creation so the app fails gracefully instead of crashing when camera hardware is briefly unavailable.
• Android: Hardened the screen-share capture lifecycle handling.
• Calling API: Consolidated call state and event models for clearer, type-safe call handling.
• Cleanup: Removed the deprecated chat module and its tests (chat was retired in 0.2.3); package description and topics updated accordingly.
• Tooling: Upgraded to flutter_lints 6.0.0; static analysis passes with no issues.

• Critical Bug Fix: Prevent crash when ACS SDK throws NSException during LocalVideoStream initialization
• iOS: Add Objective-C exception catcher to safely handle ACSLocalVideoStream init: failures
• Android: Add try-catch around LocalVideoStream constructor for defensive error handling
• Gracefully returns error to Flutter instead of crashing the app
• Addresses crash on iOS 18.6+ when camera hardware is temporarily unavailable

• Critical Bug Fix: Fixed NullPointerException crash in media statistics serialization on both platforms
• Android: Fixed null-safety in serializeOutgoingStatistics() and serializeIncomingStatistics() methods
• iOS: Fixed null-safety in serialize(outgoingStatistics:) and serialize(incomingStatistics:) methods
• Impact: Prevents app crashes when joining calls with video/mic disabled or during initial connection phase
• Details: Added null checks to gracefully handle race condition when media statistics collection starts before streams are established
• README: Updated to document chat module removal (removed in v0.2.3 for app size optimization)

• Bug Fix: Prevent crash when camera permission is denied during video call initialization
• iOS: Add AVCaptureDevice.authorizationStatus check before creating LocalVideoStream
• Android: Add ContextCompat.checkSelfPermission check before creating LocalVideoStream
• Gracefully handle denied camera permissions instead of crashing the app
