Architecture

This package leverages:

  • AVFoundation: For configuring multi-output capture sessions (AVCaptureVideoDataOutput and AVCaptureMetadataOutput simultaneously).
  • Vision Framework Mapping: To dynamically map normalized barcode coordinates across varying UI rotations seamlessly.
  • Platform Views: To render the native AVCaptureVideoPreviewLayer flawlessly beneath your Flutter overlay UI.
