Well to be honest, I did this project a long time ago. After that I once reinstalled my laptop and I didnt have the SDK installed anymore. But now I do, so I'll probably look into it some time soon I guess

You don't need Package for GradientAppBar. Just use this: AppBar( ... //backgroundColor: Colors.blue, flexibleSpace: Container( decoration: BoxDecoration( gradient: LinearGradient( begin: Alignment.topCenter, end: Alignment.bottomCenter, colors: [ Colors.amber[700], Colors.grey[800], ... ] ) ) ),
