Hello,
Giving a try with Firebase cloud messaging.
In the sample code an API Key is needed, but could not figure out where to get it. I could not find Server Key in the console.
-- A Google API Key is needed to send push notifications. It is not needed to receive notifications.
-- This number can be obtained from the Firebase Console https://console.firebase.google.com/
-- Select your project -> (Gear Icon) -> Project Settings -> Cloud Messaging -> Server key
local serverKey = "Your API key goes here."
Thank for your help.
