I read the document, both on github and Facebook developers docs.
There is only sample, nothing more. No API document.

The code to make a Graph API request is

Unfortunately the react-native-fbsdk documentation is not updated and the examples do not work well.

I got the same problem and I solved it by try and error.

To solve your problem you'll need to change your GraphRequest adding params and fields to it like this:

   {
        if (error) {
          alert("login has error: " + result.error);
        } else if (result.isCancelled) {
          alert("login is cancelled.");
        } else {

          AccessToken.getCurrentAccessToken().then(
            (data) => {
              let accessToken = data.accessToken
              alert(accessToken.toString())

              const responseInfoCallback = (error, result) => {
                if (error) {
                  console.log(error)
                  alert('Error fetching data: ' + error.toString());
                } else {
                  console.log(result)
                  alert('Success fetching data: ' + result.toString());
                }
              }

              const infoRequest = new GraphRequest(
                '/me',
                {
                  accessToken: accessToken,
                  parameters: {
                    fields: {
                      string: 'email,name,first_name,middle_name,last_name'
                    }
                  }
                },
                responseInfoCallback
              );

              // Start the graph request.
              new GraphRequestManager().addRequest(infoRequest).start()

            }
          )

        }
      }
    }
    onLogoutFinished={() => alert("logout.")}/>

You'll need to enable the Remote JS Debug to see the console.log() info. https://facebook.github.io/react-native/docs/debugging.html

And probably you need to get some permissions to get more info than names and email so it's a good idea to look the Facebook Graph API Documentation: https://developers.facebook.com/docs/graph-api/overview/
