setItem method

@override Future<void> setItem(String key, Object value)

Set item to storage

Value can be either String, bool, int or double. For any other type, it will throw DirectusError.

Implementation

@override
Future<void> setItem(String key, Object value) async {
  final instance = _instance ?? await SharedPreferences.getInstance();

  if (value is String) {
    await instance.setString(key, value);
  } else if (value is bool) {
    await instance.setBool(key, value);
  } else if (value is int) {
    await instance.setInt(key, value);
  } else if (value is double) {
    await instance.setDouble(key, value);
  } else {
    throw DirectusError(
      message: 'You can only store strings, numbers and booleans.',
    );
  }
}
