Ionic3 Angularfire listen to firestore changes
how do I listen to event after firebase cloud function had successfully updated a document? Because there is a few seconds lag while the function is running. I want to implement a loading screen and dismiss it when the function successfully updated the record.

You can use the update or set method of Angularfire to change the value of a document. those methods return a Promise, when fulfilled you can remove hte loader.
update
set
Promise
updateItem()
this.loading = true;
const item = id: 1, name: "My Item ;
this.db.doc('item/1').update(item)
.then(() => this.loading = false;;
For more exmaples look at the angularfire documents documentation
