Получение указанной выше ошибки при аутентификации Google после того, как я успешно смогу выполнить вход в Google signIn () во флаттере. Вот фрагмент кода 

final GoogleSignInAccount googleUser = await googleSignIn.signIn();
final GoogleSignInAuthentication googleAuth = await googleUser.authentication; // error in this line

final AuthCredential credential = GoogleAuthProvider.getCredential(
  accessToken: googleAuth.accessToken,
  idToken: googleAuth.idToken,
);

await auth.signInWithCredential(credential);

А далее - stacktrace
