[REQ] lstat functionality

[efstathiosntonas]

Hi @alpha0010,

I'm the maintainer of georstat/react-native-image-cache, we want to implement lstat for directories so I can get the file info.

Right now I just ls and then iterate over files to get the stat from each file and this has performance impact since the cached images could be thousands.

rn-fetch-blob has lstat , we want exactly this.

Can you implement the lstat feature? Thanks!

Named api statDir() to avoid confusion with system lstat (check status of symlink).

Thanks @alpha0010! Will try it tomorrow, I want to see how this will perform in big directories.

@alpha0010 i think we got an extra / (on iOS, haven't tested Adnroid yet):

"size": 5710544,
"type": "file"
}]

BaseDir has this format: baseDir: ${Dirs.CacheDir}/images_cache/ otherwise the images are thrown in Caches/image.png instead of Caches/images_cache/image.png if I remove the trailing /.

edit: On Android the file path is fine:

[{"filename": "fa9b55edf623d5de305fb269167a1eda44cb1daf.jpg", "lastModified": 1648803976000, "path": "/data/user/0/com.reactnativeimagecacheexample/cache/images_cache/fa9b55edf623d5de305fb269167a1eda44cb1daf.jpg", "size": 4396619, "type": "file"}]

^^ this has been fixed on 2.4.1, just for the record. Thanks @alpha0010 !
