should update the example of DownloadTaskStatus from initState

[crystalleung926]

From example, DownloadTaskStatus status = DownloadTaskStatus.(data[1]);

  IsolateNameServer.registerPortWithName(_port.sendPort, 'downloader_send_port');
  _port.listen((dynamic data) {
    String id = data[0];
    DownloadTaskStatus status = DownloadTaskStatus(data[1]);
    int progress = data[2];
    setState((){ });
  });

  FlutterDownloader.registerCallback(downloadCallback);
}

should be
DownloadTaskStatus status = DownloadTaskStatus.fromInt(data[1]);

  IsolateNameServer.registerPortWithName(_port.sendPort, 'downloader_send_port');
  _port.listen((dynamic data) {
    String id = data[0];
    DownloadTaskStatus status = DownloadTaskStatus.fromInt(data[1]);
    int progress = data[2];
    setState((){ });
  });

  FlutterDownloader.registerCallback(downloadCallback);
}

DownloadTaskStatus status = DownloadTaskStatus.fromInt(data[1]); I got Error: Enums can't be instantiated from this line

Since DownloadTaskStatus has become enum, I use this solution to fix it. DownloadTaskStatus status = DownloadTaskStatus.values[data[1] as int];

do you fit it?
