  DetailPage({this.post});

  @override

class _DetailPageState extends State<DetailPage> {
  bool pressed = false;
  String taskname,tasksector,taskpocket,tasklandmark;
  int _myTaskType = 0;
  String taskVal;
  StateModel appState;
  bool _loadingVisible = false;


  @override

//    final CounterBloc _counterBloc = BlocProvider.of<CounterBloc>(context);

    DateTime now = DateTime.now();
    String formattedDate = DateFormat('EEE d MMM y').format(now);

    // firebase location to be set
    confirm() { // for driver

      appState = StateWidget.of(context).state;
      //final userId = appState?.firebaseUserAuth?.uid ?? '';
      final w_fl = appState?.user?.w_fl ?? '';

Я хочу создать данные в базе данных только при успешной оплате , В вышеприведенных кодах ... я только что соединил два разных кода: создание данных (для базы данных) и оплата.

1) Подтверждение () и подтверждение2 () отвечают за создание данных для базы данных. 2) _handlePaymentSuccess () отвечает за успешную оплату. Пожалуйста, помогите !!!

Answer 1

Используйте shared_preferences, добавить в list.dart:

  void saveName() {
    savedNamePreferences(taskVal).then((_) {});}

Future<bool> savedNamePreferences(String name) async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  prefs.setString("name", name);
  return prefs.commit();
}

Future<String> getNamePreferences() async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  String name = prefs.getString("name");
  return name;
}

И вызвать getNamePreferences () в другом классе, т.е. check.dart
