Alpha Bot Try this code:

@override
void initState() {
  WidgetsBinding.instance.addPostFrameCallback((_) => _afterLayout(context));
  super.initState();
}

Then create this method and navigate to your Home:

_afterLayout(BuildContext context) {
    // TODO
 Navigator.push(context, MaterialPageRoute(builder: (context)=>Home()));
}
