RNFetchBlob.fs.stat size of directory is incorrect

[HermitCarb]

Hi ! I met an error When in use RNFetchBlob.fs.stat couldn't get correct size of directory. I want to get whole directory RNFetchBlob.fs.dirs.CacheDir's size, which contain cached images by react-native-img-cache. But get wrong data, directory size smaller than file or sub-directory.

Versions

"react": "^16.0.0",
"react-native": "^0.50.0",
"react-native-fetch-blob": "^0.10.8",

Code

    RNFetchBlob.fs.stat(RNFetchBlob.fs.dirs.CacheDir)
      .then((stats) => {
        console.log(stats);
        if (stats && stats.size) {
          this.setState({ cacheSize: stats.size });
        }
      })
      .catch(() => { });
    RNFetchBlob.fs.stat(`${RNFetchBlob.fs.dirs.CacheDir}/react-native-img-cache`)
      .then((stats) => {
        console.log(stats);
      })
      .catch(() => { });
    RNFetchBlob.fs.stat(`${RNFetchBlob.fs.dirs.CacheDir}/react-native-img-cache/7393ba9b6f2f1b0e379e2c7ebf219b515d85f666.jpg`)
      .then((stats) => {
        console.log(stats);
      })
      .catch(() => { });

But Print Result

Anything wrong in my code? Or I need traverse all cache sub-directory and calculate directory and files' size?

I use another method. But I think it is not the best way. Here is the snippet

  componentDidMount() {
        this.cacheSize = 0
        this._statisticsCacheSize(RNFetchBlob.fs.dirs.CacheDir)
    }

    _statisticsCacheSize(path) {
        RNFetchBlob.fs.lstat(path).then((lstat => {
            for (let stat of lstat) {
                if (stat.type === "directory") {
                    this._statisticsCacheSize(stat.path)
                } else {
                    this.cacheSize += parseInt(stat.size)
                    this.setState({
                        size: this.cacheSize
                    })
                }
            }
        })).catch(err => {
            console.warn(err)
        })
    }

Yeah I'm doing the same as @echokk11 however its obviously not the best way.

My guess is that by reporting 320 bytes as the size of the directory is that our stat method is literally getting the size of just the folder with various folder metaData. I don't think that information would ever be of value to anyone so I think we should consider this a bug and report the size of a directory as the true size with the aggregation of all the children within that directory.
