一直卡在压缩这，代码如下

`final newCompressedPicpath = join((await getTemporaryDirectory()).path, '${DateTime.now().millisecondsSinceEpoch}.png');

    CompressObject compressObject = CompressObject(
      imageFile: File(picturePath),
      path: newCompressedPicpath,
      quality: 80,
      step: 9,
      mode: CompressMode.AUTO
    );
    var path =await (Luban.compressImage(compressObject));`
