Issue Description

Got freezed on downloading large file (movie file eg. mp4,mkv). It's back when downloading done. User can't press any button on screen until downloading done.

My Code

await _dio.download(model.url, savePath,
          onReceiveProgress: (received, total) {
        if (total != -1) {
          model.progress =
              int.parse((received / total * 100).toStringAsFixed(0));
          _showNotification(model);
        }
      })
