$server_key = "####";

$topic = "/topics/reminder";
$type = "reminder";



//create http request to firease server
//request need 2 section : 1.header section 2. payload section
//add push notification in payload section

//header section for http request : that content authorization key and content_type of this application

//below are the header section of the http request
$headers = array(
            'Authorization:key='.$server_key,
            'Content-Type:application/json'
        );



/*

Please check this reference about when onMessageReceived() method is fired.

onMessageReceived() is fired only if app is in foreground for notification messages but for data messages, it will always get handled.
