    cropType: CropType.rect, // currently for android
  ),
);

• save file to album

• save network file to album

because the HTTP request is uncontrollable in plugin(such as progress),you must download file ahead of time

void save() async {
    File file = await downloadFile('https://xxx.example.com/xx.png');
    bool res = await ImagesPicker.saveImageToAlbum(file, albumName: "");
    print(res);
}

Future<File> downloadFile(String url) async {
  Dio simple = Dio();
  String savePath = Directory.systemTemp.path + '/' + url.split('/').last;
  await simple.download(url, savePath,
      options: Options(responseType: ResponseType.bytes));
  print(savePath);
  File file = new File(savePath);
  return file;
}
