My Flutter Package

A Flutter package for image processing that detects and crops faces from images. This package provides a simple and efficient API for face detection and cropping using advanced computer vision algorithms.

Features

  • Face Detection: Detects faces in images and returns their bounding boxes.
  • Face Cropping: Crops detected faces and returns them as separate image segments.

Installation

To use this package, add it to your pubspec.yaml file:

Future<void> detectFace() async {
  try {
    final ByteData data = await rootBundle.load('assets/male.jpg');
    final Uint8List imageData = data.buffer.asUint8List();
    final result = await FaceAnalyzer.instance.detectFaces(image: imageData);
    setState(() {
      bytesList = result.cast<Uint8List>();
    });
  } on PlatformException catch (e) {
    debugPrint(e.toString());
  }
}

        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $iOSVersion
      end
    end
  end
end
