I can't thank you enough for this video! I am "learning" Flutter in school but have had to rely on the internet and your video is one of the most helpful I have found to date. Cloud functions are so useful and I appreciate you creating this video!

Hi Trey Mumba from South Africa here, great video just a quick question can I use this to update potentially millions of records in a database

[@TreyHope]

Hey Mumba. Yes, you absolutely can use cloud scheduler functions to update millions of records in a database.

[@b4sti3n77]

thank you for that tuto but i'm really struggling doing that in flutterflow :( Do you know how to integrate that into flutterflow ? when a button is clicked for exemple

[@TreyHope]

Hello, I’m not sure how to do this in FlutterFlow. I’m not that experienced with that software.

[@tibejeanmarc]

Are we charged by firebase when we use it or it’s totally free ?

[@TreyHope]

Great question. You're only charged based on your usage. As long as you make under 2 million invocations/month with Cloud Functions, you won't be charged.

Hey man, I'm trying to use this method to update data in my firestore db, and the function is succeeding and getting executed every minute but the data in firesore isn't updating. Do you know what could be the reason? This is my function: const functions = require('firebase-functions'); const admin = require('firebase-admin'); admin.initializeApp(functions.config().firebase); exports.myScheduledCloudFunction = functions.pubsub.schedule('* * * * *').timeZone('Asia/Kuala_Lumpur').onRun(async (context) => { admin.firestore().collection('users').get().then(function(querySnapshot) { querySnapshot.forEach(function(doc) { admin.firestore().collection('users').doc(doc.id).collection('habits').get().then(function(querySnapshot) { querySnapshot.forEach(function(habitDoc) { admin.firestore().collection('users').doc(doc.uid).collection('habits').doc(habitDoc.id).ref.update({ 'iscompleted' : false, 'completedcount': 0 }) }) }) }) }) return null; });

It’s a bit hard to read what’s going on here. If you want, you can follow me on Twitter and we can discuss it more there. @trey.codes
