Push notifications setup

This plugin works in combination with the firebase_messaging plugin to receive Push Notifications. To set this up:

• First, implement firebase_messaging
• Then, add the Firebase server key to Intercom, as described here (you can skip 1 and 2)
• Follow the steps as described here to enable push notification in iOS.
• Ask FirebaseMessaging for the token that we need to send to Intercom, and give it to Intercom (so Intercom can send push messages to the correct device), please note that in order to receive push notifications in your iOS app, you have to send the APNS token to Intercom. Below example uses firebase_messaging to get either the FCM or APNS token based on the platform:

final firebaseMessaging = FirebaseMessaging.instance;
final intercomToken = Platform.isIOS ? await firebaseMessaging.getAPNSToken() : await firebaseMessaging.getToken();

Intercom.sendTokenToIntercom(intercomToken);

Now, if either Firebase direct (e.g. by your own backend server) or Intercom sends you a message, it will be delivered to your app.

Web

Add the below script inside body tag in the index.html file located under web folder

<script>
    window.intercomSettings = {
        hide_default_launcher: true, // set this to false, if you want to show the default launcher
    };
    (function(){var w=window;var ic=w.Intercom;if(typeof ic==="function"){ic('reattach_activator');ic('update',w.intercomSettings);}else{var d=document;var i=function(){i.c(arguments);};i.q=[];i.c=function(args){i.q.push(args);};w.Intercom=i;var l=function(){var s=d.createElement('script');s.type='text/javascript';s.async=true;s.src='https://widget.intercom.io/widget/';var x=d.getElementsByTagName('script')[0];x.parentNode.insertBefore(s, x);};if(document.readyState==='complete'){l();}else if(w.attachEvent){w.attachEvent('onload',l);}else{w.addEventListener('load',l,false);}}})();
