BREAKING CHANGES

• Architectural Refactor & State Management:
  • Removed flutter_bloc: The dependency on flutter_bloc has been completely removed. State management is now handled by a simpler controller pattern using ValueNotifier and Listenable. Code using BlocProvider or BlocBuilder must be migrated.
  • Renamed Main Widget: The primary widget CameraPreviewView has been renamed to NativeCameraView for better clarity and consistency. All implementations must be updated.
• Simplified Package Structure:
  • Removed plugin_platform_interface: This dependency has been removed to streamline the package architecture.

0.0.4

• iOS:
  • Critical Stability Fix (Lifecycle & Deinit): Resolved persistent EXC_BREAKPOINT / EXC_BAD_ACCESS crashes during deinit by implementing a more robust and synchronized AVFoundation resource cleanup on the sessionQueue. This includes corrected order for removing outputs and nilling delegates (delegate is nilled after removal from session, all within the same synchronized block).
  • Preview Fit Enhancement (contain mode): Implemented top-alignment for the "contain" preview mode. When this mode is active, if the camera video's aspect ratio (when scaled to fill the view's width) results in a height shorter than the view, the preview will now fill the width and align to the top, rather than being vertically centered.
  • Feature: WYSIWYG Photo Cropping for "cover" mode (iOS): Captured photos in "cover" mode are now automatically cropped using Core Graphics to precisely match the visible area of the AVCaptureVideoPreviewLayer. This calculation uses metadataOutputRectConverted(fromLayerRect:) and the cropping process is performed asynchronously.
  • Swift Code Correctness: Fixed a 'guard' body must not fall through compiler warning in setupCamera by using throw for early exit within a do-catch block, improving the reliability of camera configuration.
  • Enhanced internal logging for easier debugging of camera lifecycle and preview adjustments.
• Android:
  • Feature: WYSIWYG Photo Cropping for "cover" mode.
    • Implemented photo cropping for the "cover" preview fit mode (which uses PreviewView.ScaleType.FILL_CENTER on Android). Photos captured using ImageCapture are now automatically cropped to match the visible area displayed in the PreviewView.
    • This provides a "What You See Is What You Get" (WYSIWYG) experience, ensuring the final saved image corresponds to what the user saw.
    • The cropping logic involves Bitmap manipulation and correctly handles EXIF orientation of the original image to ensure accurate cropping results.

0.0.3

• iOS: Enhanced camera stability, fixed critical lifecycle bugs, and improved feature reliability.
  • Resolved EXC_BAD_ACCESS crashes encountered during camera switching by overhauling the resource deallocation process (deinit) and ensuring thread-safe operations for AVFoundation objects.
  • Corrected switchCamera behavior: The iOS native side now allows Flutter to manage view recreation, preventing conflicting camera setups and teardowns between old and new platform view instances.
  • Fixed an NSGenericException caused by improper AVCaptureSession startRunning() calls relative to beginConfiguration/commitConfiguration.
  • Addressed Swift-specific issues: resolved a force-unwrap error on non-optional AVCaptureDevice and a guard statement fall-through warning during camera setup, improving code correctness.
  • Significantly improved the "capture last frame on pause" feature by utilizing AVCaptureVideoDataOutput for more reliable frame grabbing, fixing previous issues that resulted in blank images.
  • Strengthened isDeinitializing checks in delegate callbacks and various functions to improve safety during instance deallocation.
  • Ensured each CameraPlatformView instance uses unique DispatchQueue instances for its sessionQueue and videoDataOutputQueue to prevent potential cross-instance conflicts.
