createState method

@override BaseStatePage<BaseStatefulPage<PageArgument?>> createState()

由于此处需要用到当前State 所以暂时忽略"no_logic_in_create_state"规则

Implementation

@override
// ignore: no_logic_in_create_state
BaseStatePage<BaseStatefulPage> createState() {
  final state = createPageState();
  states.first = state;
  return state;
}
