[QUESTION] How to use RNFetchBlob.fs.df() ?

Using xcode and iPhone 6S emulator, iOS 10.2
Using react-native 0.42

I am working on a project using RNFS, but since they recommend to use RNFetchBlob, I'm going to refactor everything. Among other features, I'm using RNFS's getFSInfo() in order to retrieve free storage space left. So, as 0.10.0 introduced df(), I would like to know how it works (wiki section is empty).

I have those noticeable differences :

// RNFS
{
  totalSpace: 248828264448 (~ 248 GBytes)
  freeSpace: 216244088832 (~ 216 GBytes)
}

// RNFetchBlob
{
  free: 1495726032 (~ 1.5 GBytes)
  total: -279838720 (~ -279 MBytes)
}

Why those differences ? Is it a matter of emulator's storage/laptop storage ? Why is RNFetchBlob's total a negative number ?

@ValBerthe , we've fixed the issue #276 but not yet release to npm. You can try to install the package from branch issue-276 and see if it's working properly, thanks!

Updated to RNFetchBlob 0.10.4.

df() seems to still have a weird behavior.

// RNFetchBlob
{
  free: -796413952 (~ -796 MBytes)
  total: -279838720 (~ -279 MBytes)
}

@ValBerthe , I have committed a fix to branch issue-301, please try to install the package from the branch and see if that works.

@wkh237 Updated RNFetchBlob 0.10.4#issue-301 :

Output is

{
  free: 492335104 (~ 492 MBytes)
  total: -279838720 (~ -279 MBytes)
}

Free space seems better, even though it is not the same value as expected by RNFS. Total space is still the same.

@ValBerthe , thanks for quick response. I've just changed the implementation, you can install the package again from the same branch issue-302` now 👍

@wkh237 Updated RNFetchBlob 0.10.4#issue-302 :

The output is the same as previously. Have you managed to run a working version of the feature ? Are freeFileSystemSizeInBytes and fileSystemSizeInBytes accurate enough ?

I'll check this out myself when I have a minute.

@ValBerthe , I can only test it on the simulator but the result looks to make sense.

Not sure if I missed something ?
