You need to first use a document picker - use
react-native-document-picker https://github.com/Elyx0/react-native-document-picker Then create a form data object in callback of document picker

data = new FormData();

                data.append('resource', {
                    name: res.fileName,
                    uri: res.uri, type: res.type
                });

var req = {
  method: "POST",
  headers: {

    'Auth-Identifier': access_token,

  },
  body:file
}

use above request in your fetch call. It will work for you.
