为什么 GoogleSignInAccount 会出现此错误？

Question

I'm trying to use Google Sign In Account In but I have error this my code

class AuthViewModel extends GetxController{
  GoogleSignIn _googleSignIn = GoogleSignIn(scopes: ['email']);
  FirebaseAuth _auth = FirebaseAuth.instance;
  @override
  void onInit() {
    // TODO: implement onInit
    super.onInit();
  }
  @override
  void onReady() {
    // TODO: implement onReady
    super.onReady();
  }
  @override
  void onClose() {
    // TODO: implement onClose
    super.onClose();
  }
  void googleSignInMethod()async{
    final GoogleSignInAccount googleUser = await _googleSignIn.signIn();
}
}
