I've tried to run your project but I'm still making mistakes.
I'm on version Flutter 3.10
here is my console debug:

Hello,
I'm also trying to compile/run this project.
After a lot of tests to port the project to Flutter 3.16 - SDK 34 I obtained the same error.
Finally I added some Log.x("AUTO", ..) in the java side and I maybe found the problem looking in the Logcat window:

...

So the main problem in my understanding is:

...
Caused by: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/car/Car;
at com.example.flutterandroidautoos.flutter_android_auto_os.FlutterAndroidAutoOsPlugin.setupChannels(FlutterAndroidAutoOsPlugin.java:77)
at com.example.flutterandroidautoos.flutter_android_auto_os.FlutterAndroidAutoOsPlugin.onAttachedToActivity(FlutterAndroidAutoOsPlugin.java:119)
...

Where the Car class comes from?
Is there any additional library to install / insert in the project or in the mobile??

Hope this help ..

If I remove all the Car class references, the call to getPlatformVersion method returns the correct value without errors.

The app MUST run on the device on the car!
Only there class Car is present (or better in Android Auto OS)!
