🔗 Using GraphQL with Flutter: A tutorial with examples

GraphQL is getting used more and more by API providers. There are some packages in Flutter/Dart that help you with using it in your app. I believe that _graphql_flutter _ is one of the best and in this article, [Chidume Nnamdi](https://blog.logrocket.com/author/chidumennamdi/) shows you how to use it with a tutorial.

Tools 🛠

🔗 Simplify test new features in Flutter app with debug_friend

Stanislav Ilin published a package to help you during the development of a Flutter app. The package is called _debug_friend _ and it adds some views to your app giving information like device info, the possibility to delete app data, and viewing detail UI values, like sizes and borders. A real debug friend, indeed.

Backend 🗄

Appwrite recently added Magic URL as a password-less authentication method. Learn how to implement it in your Flutter app with this tutorial by Damodar Lohani.

Others 🤷‍♂️

🔗 Add CarPlay to your Flutter App 🚗

My first Flutter app was a simple screen showing whether there was an available parking spot in the company parking lot. If you were too late and all spots were taken, you had to park in a public parking lot down the street and walk back. The app saved you the time to check at the company facilities whether there was room for your car or not: if the app told you there was no room, you just went directly to the public parking space. A colleague asked me if we could have the app on CarPlay, but that was not possible at the time. Now, with the _flutter_carplay _ package __ published by [Oguzhan Atalay](https://hashnode.com/@oguzhan), we can try it again, once we are all back to the office.

That’s it for this week.
