CameraCaptureScreen class

A ready-to-use camera screen that:

  • Streams live camera frames
  • Runs real-time blur detection via NativeOpencv
  • On manual capture, runs ID-card perspective crop via NativeOpencv
  • Optionally posts the cropped PNG to an OCR endpoint and displays results

Basic usage (no OCR)

final Uint8List? result = await Navigator.push(
  context,
  MaterialPageRoute(builder: (_) => const CameraCaptureScreen()),
);

With OCR

final Uint8List? result = await Navigator.push(
  context,
  MaterialPageRoute(
    builder: (_) => const CameraCaptureScreen(
      ocrBaseUrl: 'https://your-ocr-server.com',
    ),
  ),
);

The screen pops with the cropped RGBA Uint8List when the user taps "Use This", or null if they dismiss without capturing.

Properties

hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
ocrBaseUrl → String?
Base URL of the OCR server (e.g. 'http://192.168.1.10:8212'). When null, OCR is skipped and only the cropped image is shown.
final
ocrLanguage → String
OCR language parameter sent to the server. Defaults to 'eng+khm'.
final
ocrPath → String
OCR endpoint path appended to ocrBaseUrl. Defaults to '/api/ocr/id-card/'.
