How to use flutter firebase functions for free

Question

I am getting this error:

Error: Your project myproject must be on the Blaze (pay-as-you-go) plan to complete this command. Required API cloudbuild.googleapis.com can't be enabled until the upgrade is complete. To upgrade, visit the following URL:

https://console.firebase.google.com/project/fluttershare-d057e/usage/details

while using this command: firebase deploy --only functions which means I have to purchase flutter functions to proceed. Now I want to know is there any alternative way to deploy function like onCreate() free or can we build these functions manually for firebase? I am using flutter technology.

Based on @Brugui and @FrankvanPruffelen answers, you need the Blaze plan in order to use Cloud Functions, however, it doesn't necessarily mean you'll have to pay for Cloud Functions usage as there's a significant free tier.
