React-native-fetch-blob: How to use cache?

[nielsswinkels]

• please provide the version of installed library and RN project.
  0.10.2

I have set fileCache : true, in RNFetchBlob.config. But if I try to fetch when I have no internet connection, it only goes to catch() because of the Unable to resolve host"example.com":No address associated with hostname. So how would I retrieve the path of the cached file in this case? or am I misunderstanding it, and should I save that path somewhere myself, and use it in case I get the error?

update:

It seems a key is required in the config as well (must be string). Please write this more clearly in the documentation.

.config({
        fileCache : true,
        key: ''+videoFile.id,
      })
