How to send emails using Flutter? Trigger automatically using Firebase Extension and SendGrid API.

In this video, I show how to configure SendGrid API and Firebase Extension called 'Trigger Email' to automatically send emails using Flutter.
The emails can be used in shopping apps to confirm orders when a user successfully makes a purchase or to generally send emails using onPressed of a button.

To configure extension, you need to fill in only 3 fields:
1) SMTP Connection URI
2) Email Documents collection, and
3) Default FROM address
For SMTP Connection URI, use API key details from SendGrid API:
smtps://apikey:@smtp.sendgrid.net:465
Your 'username' would be 'apikey'. Only replace the 'password' in hint text with your API Key and the above URI shall work!

Apparently Trigger email isn't free, is it?

[@AdityaThakurXD]

It isn't. Requires the Firebase - Blaze plan. I have mentioned it in the video too!
