nitro_camera 0.0.2

High-performance vision-camera-style plugin built on the Nitro FFI bridge — photo/video capture, code scanning, frame processing, and GPU filters with zero method-channel overhead.

0.0.2

Added

• High-speed (slow-motion) recording — startHighSpeedRecording(path, fps) / stopHighSpeedRecording(): 120/240 fps → 8× slow-mo.
• Native detector plugin registry — NitraDetectors.register(name, factory); select custom detectors from Dart by name. barcode / face built-in.
• Manual focus & exposure — setFocusDistance, setManualExposure, setAutoExposure (clamped natively).
• Keep-screen-on — setKeepScreenOn(bool) (FFI, no extra plugin).
• Frame helpers — FrameData.resized / cropped / rotated.
• Scanner ROI — CodeScanner(windowFraction: …).
• Multi-cam discovery — typed ConcurrentCameraSet + getConcurrentCameraSets.

Fixed

• Android: recorded video no longer squished — encoder size matches session aspect.
• Android: fixed a persistent-surface teardown race that could crash the camera.
• iOS: back↔front switch with manual white balance no longer crashes.
• RAW/DNG on HALs that gate it now fails fast + falls back to JPEG (no freeze).
• Android: RecordingResult.durationMs was inflated by the encoder's finalize latency (a 2 s clip could report 4.7 s). It now reads the finalized container's own duration, with a stop-requested wall clock as fallback.
• Videos no longer save sideways — recordings ignored the requested orientation and were stored in sensor orientation.
• isRecording no longer gets stuck on when a recording ends by itself (duration/file-size limit or encoder failure) — Dart is now notified.
• Encoder crashes are no longer silent — a dying recorder stops the recording, deletes the unusable file and emits an error event.
• Photos no longer save 90° off in landscape, on both platforms; PhotoResult.orientation / isMirrored now describe the saved file accurately.
• A failed stop no longer returns a truncated, unplayable file as success — it throws RecorderException('recorder/finalize-failed'). Adds RecordingFinishedReason.failed and RecordingResult.isFinalized.
• initialize() without a size/format now targets 1080p instead of the platform's first format (4K on Android, smallest on iOS).
• iOS: an unsupported setFrameFormat value no longer crashes the app.
• iOS: external and Continuity Cameras (iOS 17+) now appear in getAvailableCameraDevices().
• Android: opening external/UVC cameras that report no preview sizes no longer crashes; they're also labelled as external instead of phone lenses.
• Android: session state no longer reports bgra when frames are delivered as yuv420.

Changed

• Upgraded to nitro 0.7.5.

0.0.1 - 2026-07-12

Initial release.

• Curated exports: nitro_camera.dart exposes the high-level API only. The raw FFI layer moved to package:nitro_camera/native.dart and the FPS HUD to package:nitro_camera/debug.dart.
• Typed device model: positions, lens types, hardware level, extensions, auto-focus system and stabilization modes are enums rather than ints.
• Typed errors: failures throw CameraException subtypes (PermissionException, DeviceException, SessionException, CaptureException, RecorderException) with stable domain/code strings.

Fixed

• frameStream delivered frames from other open sessions; it is now scoped to its own session.
• PreviewMode.platformView rendered nothing off-Android; it now falls back to the texture path.
• Pinch-to-zoom clamped to a hardcoded 1–8× instead of the device's real range.
• Unknown values from a newer native layer are skipped instead of throwing a RangeError.
