Is there a way to load async data on InitState method?

I'm a looking for a way to load async data on InitState method, I need some data before build method runs. I'm using a GoogleAuth code, and I need to execute build method 'till a Stream runs.

My initState method is:

 @override
  void initState () {
    super.initState();
    _googleSignIn.onCurrentUserChanged.listen((GoogleSignInAccount account)     {
      setState(() {
        _currentUser = account;
      });
    });
    _googleSignIn.signInSilently();
  }

I will appreciate any feedback.

You can create an async method and call it inside your initState

@override
void initState () {
  super.initState();
  WidgetsBinding.instance.addPostFrameCallback((_){
    _asyncMethod();
  });
        
}

_asyncMethod() async {
  _googleSignIn.onCurrentUserChanged.listen((GoogleSignInAccount account)     {
    setState(() {
      _currentUser = account;
    });
  });
  _googleSignIn.signInSilently();
}
