flutter的photoView插件有人用过吗，在预览多张图片时，如果地址只能future获取该如何操作

Question

PhotoViewGalleryPageOptions _buildItem(BuildContext context, int index) {
 final item = (widget.bloc.state as AssetPhotoInfo).images[index].thumbDataWithSize(width, height).;
 return PhotoViewGalleryPageOptions(
     imageProvider: MemoryImage(item),
     minScale: PhotoViewComputedScale.contained * 1,
     maxScale: PhotoViewComputedScale.covered * 2,
 ); }

代码中item是从相册获取的图片，这个图片是异步获取的，所以得到的值是future<Uint8List>，该类型如果放在memoryImage中会报错，试了多种方法依然无果，futureBuilder由于返回的是widget，也不适用
