title: How to get FB Access Token with Expo
body: <p>I'm building app where i need to make Facebook Graph API requests in many places. But i dont know how to retrieve access token and then make Graph API request.</p>
  
  <p>I'm using Expo, React Native and Firebase. I would like to do it without installing Xcode and/or Android Studio.</p>
  
  <p>Login is working fine. My code is below:</p>
  
  <pre><code>async loginWithFacebook() {
  try {
    const {
      type,
      token,
      expires,
      permissions,
      declinedPermissions,
    } = await Expo.Facebook.logInWithReadPermissionsAsync('&lt;APP_ID', {
      permissions: ['email', 'public_profile'],
    });
    if (type === 'success') {
      const credential = f.auth.FacebookAuthProvider.credential(token)
      f.auth().signInAndRetrieveDataWithCredential(credential).catch((error) =&gt; {
        console.log(error)
      })
      var that = this;
      const response = await fetch(`https://graph.facebook.com/me/?fields=id,name&amp;access_token=${token}`);
      const userInfo = await response.json();
      this.setState({userInfo});
      this.setState({
      dataSource: userInfo.data,
      isLoading: false,
      });
    } else {
      // type === 'cancel'
    }
  } catch ({ message }) {
    alert(`Facebook Login Error: ${message}`);
  }
  }
  </code></pre>
  
  <p>Can someone help me and give me some tips how i can use access token everywhere in my app?
  Thank you in advance</p>
