Unhandled Promise Rejection - listeners is not defined

[funkysoul]

I'm getting this "Warning" after successfully uploading an Image to Firebase.
I'm using the sample code provided in the example (small modifications nothing fancy, only filename and firebase location logic).

After dismissing this message I also get a further warning only in the console:
"Failed to execute 'readAsText' on 'FileReader': parameter 1 is not of type 'Blob'."

I'm not sure if I'm doing anything wrong or forgot a step in-between.. Many thanks for your help

RN: 0.37.0
Lib: 0.10.0

@funkysoul , thanks for reporting the issue, I think the problem is here :

https://github.com/wkh237/react-native-fetch-blob/blob/master/src/polyfill/EventTarget.js#L74

the missing this before listeners[i]
