Native plugin owning AVCaptureSession + AVAssetWriter, mirroring
telegram-iOS's Camera module decomposition. Photo + video capture with
the writer-track transform set from a per-call orientation snapshot
(the three-way preview/capture/device split that camera_avfoundation
can't give us).
Modules:
CameraPlugin channels + per-handle instance map
CameraInstance session + texture + outputs + recorder
CameraSession AVCaptureSession + runtime-error/interrupt obs
CaptureDevice front/back discovery, per-device config
PhotoOutput AVCapturePhotoOutput, per-shot orientation
VideoRecorder AVAssetWriter, lazy inputs, pending-audio queue,
stop()/cancel() pair (matches telegram)
PreviewSink CVPixelBuffer → FlutterTexture
AudioSession setCategory + setActive(true) (only-widen)
DeviceOrientationBridge
Recorder details:
- Lazy videoInput/audioInput on first sample, sourceFormatHint:.
- Audio settings derived from CMAudioFormatDescriptionGet*
+ recommendedAudioSettingsForAssetWriter, gated startWriting.
- Stop sets stopSampleTime; next sample crossing it triggers
maybeFinish → finishWriting. No watchdog — telegram pattern.
- cancel() drops pending audio + cancelWriting + deletes file,
used by CameraInstance.dispose when teardown finds in-flight
recording.
- Diagnostic stream → ux/camera/events {event: "diagnostic"}.
Dart surface extensions over Phase 1:
- UxCameraValue.audioPermissionGranted
- UxCameraController.refreshAudioPermission()
- Static UxCameraController.audioPermissionGranted() /
openSystemSettings()
- UxCameraDiagnostic event variant
- FakeUxCameraBackend.{emitDiagnostic, audioPermission,
openSettingsCalls}
Tests: 32/32 in test/camera (controller + channel) green.
