I've been trying to create a contact form for my flutter project. The contact form is composed of two steps. First, the user provides their email and then describes their issue. Once the user presses submit, I want to receive an email on my end. I've look at several packages like mailer and flutter_email_sender. However, they don't seem to offer good solutions; mailer requires that I provide the password to my email address in my code (opening up the possibility for vulnerabilities). Flutter_email_sender simply opens up an email app on the phone.

Recently I've come across the perfect solution, Firebase's new extension Trigger Email. Although the extension seems promising, I can't find any resources outlining proper implementation of Trigger Email in Flutter.

Can you please provide an example of how Trigger Email can be implemented in Flutter project?

    "Use this extension to render and send emails that contain the information from documents added to a specified Cloud Firestore collection." So to send an email you write a document to Cloud Firestore. For examples of writing to Cloud Firestore from Flutter, see https://firebase.flutter.dev/docs/firestore/usage – Frank van Puffelen Mar 30 '21 at 02:04
  • Oh.. this is much simpler than I thought, thank you! – Joe Mar 30 '21 at 03:48
  • @FrankvanPuffelen Is it also possible to attach files (e.g. from Firebase Storage)? – BugsOverBugs Oct 18 '22 at 19:59

From the documentation of the extension:

Use this extension to render and send emails that contain the information from documents added to a specified Cloud Firestore collection.

So to send an email you write a document to Cloud Firestore. For examples of writing to Cloud Firestore from Flutter, see the FlutterFire documentation for examples of this.
