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.
