How to navigate inside initState() in Flutter

Question

@override
void initState() {
final Future<bool> is_initialized = IsInitialized();

if (is_initialized == false) {
  GenerateDefaultPreferences();
  Navigator.push(context, MaterialPageRoute(builder: (context) => LanguageSelection())); //?
} else {
  SynchronizeDLIfSet();
}
  }

This is in my stateless widget. How can I navigate inside an initState() in Flutter?

I am trying to make it navigate to LanguageSelection() if the app didn't initialize before.

@override
void initState() {
  super.initState();
  final Future<bool> is_initialized = IsInitialized();

  is_initialized.then((value) {
    if (!value) {
      GenerateDefaultPreferences();
      WidgetsBinding.instance.addPostFrameCallback((_) {
        Navigator.push(context, MaterialPageRoute(builder: (context) => LanguageSelection()));
      });
    } else {
      SynchronizeDLIfSet();
    }
  });
}
