Create a widget to load and edit an image:

  ImgCrop(...),  //  ImageProvider
  ImgCrop.file(...) // Image file
  ImgCrop.asset(...) // Image assets your local

final imgCropKey = GlobalKey<ImgCropState>();

Widget _buildCropImage() {
  return Container(
      color: Colors.black,
      child: ImgCrop(
        key: cropKey,
        chipRadius: 150,  // crop area radius
        chipShape: ChipShape.rect,
        chipRatio: 2 / 1,
        image: FileImage(imageFile), // you selected image file
      ),
