This week in Flutter #79: Black Friday deals?

There is a big black Friday sale on Kodeco. I am biased because I occasionally do some tech editing work at Kodeco. Books and courses are created by passionate developers, and you should have a look at what is available for Flutter. Kodeco is the new raywenderlich.com.

Related to resources to learn Flutter I will have an announcement in the next issue of this newsletter. Stay tuned!

Backend 🗄

Flutter Authentication and Authorization with RLS

by Tyler Shukert

Supabase is an open-source backend that you can self-host. You can see it as an alternative to Firebase and Appwrite, in particular if you want to use a relational database. This article is a tutorial on using Flutter as a frontend for a Supabase backend. You might want to read the first part of the tutorial before diving into this article.

I like the separation of the two articles, you learn about updating the database schema, about deeplinks, needed to open the app after the user confirms their email address, and about adding authentication, which is the main subject of this article.
