react-native-signature-capture Android – Unable to send image to api as formdata

  android, react-native, webapi

I’ve a react app that use react-native-signature-capture component ( to acquire user signature.
After many attempts I was able to save the file with the signature in the camera roll of my android device.
Now I should send the file to a webapi that requires formdata as input but I can’t find the way to do it.

Can someone help me?
