Finally got it with https://pub.dev/packages/image_gallery_saver. Here is my working code:
void _saveNetworkImage() async {
final bytes = await rootBundle.load(widget.imagePath); // imagePath like "assets/images/my_image.jpg"
Uint8List clockBytes = bytes.buffer.asUint8List();
final result = ImageGallerySaver.saveImage(clockBytes);
print(result);
}
}
