put method

@override Future<bool> put(String key, dynamic value)

value为自定义对象时好想只会存在内存

Implementation

@override
Future<bool> put(String key, dynamic value) async {
  try {
    _localStorage[key] = value == null ? _undefine : value.toString();
    return true;
  } catch (e) {
    return false;
  }
}
