onInit method

@override void onInit()

Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.

@override
void onInit() {
  final his = Application.preferences.getStringList(HISTORY);
  if (his != null) {
    historys = his.map((e) {
      return HistoryModel.fromMap(e);
    }).toList();
  }
  super.onInit();
}
