getFacesEntity method

Future<FacesEntity> getFacesEntity(String imageId)

Returns FacesEntity which contains original image size and rectangles of faces

Example:

FacesEntity entity = /* FacesEntity */
RenderBox renderBox = context.findRenderObject();

return FractionallySizedBox(
  widthFactor: 1,
  heightFactor: 1,
  child: Stack(
    children: <Widget>[
      Positioned.fill(
        child: Image(
          image: UploadcareImageProvider(widget.imageId),
          fit: BoxFit.contain,
          alignment: Alignment.topCenter,
        ),
      ),
      ...entity
          .getRelativeFaces(
        Size(
          renderBox.size.width,
          renderBox.size.width /
              entity.originalSize.aspectRatio,
        ),
      )
          .map((face) {
        return Positioned(
          top: face.top,
          left: face.left,
          child: Container(
            width: face.size.width,
            height: face.size.height,
            decoration: BoxDecoration(
              color: Colors.black12,
              border: Border.all(color: Colors.white54, width: 1.0),
            ),
          ),
        );
      }).toList(),
    ],
  ),
);

Implementation

Future<FacesEntity> getFacesEntity(String imageId) async {
  final response = await _detectFaces(imageId);

  return FacesEntity.fromJson(response);
}
