Thank you @Samuel.

I finally succeed to get user information from Facebook login because of your help!

But I struggled to figure out how can I get username and email literally from the result object cause I am a newbie in React & Javascript.

P.S. result["name"] is the point because it is object!!

So I added some code to yours for other people like me.

If you don't like using your code, just tell me that.

 {
      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)

                // Here's my code
                alert('Success fetching data: ' + result["name"].toString() + 
                ", " + result["email"].toString()); 
                /*  
                if(your DB already got this email or something unique) {
                  // SignIn()
                } 
                // when your DB doesn't have this email
                else {
                  // Do signUp() with this infomation and SignIn()
                }
                */
              }
            }

            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.")}/>
