Answer 1

You have to define static before variable, Like this

  class SharedPrefHelper {
  static SharedPreferences? sharedPref;

  static Future<void> initSharedPreferences() async {
    print("Running get instance");
    sharedPref = await SharedPreferences.getInstance();
  }
}

Future<void> initiateAuthBloc() async {
  await SharedPrefHelper.initSharedPreferences();
}
