Flutter: remove all saved shared preferences

I want to delete all saved shared preferences when the user taps on logout. Are there any ways to do this in a single shot without deleting one by one?

Solution

  • I use shared_preferences plugin:

    In pubspec.yaml

    dependencies:
  flutter:
    sdk: flutter

  shared_preferences: ^0.4.3

    And in dart file:

    import 'dart:async';
import 'package:shared_preferences/shared_preferences.dart';
...
SharedPreferences preferences = await SharedPreferences.getInstance();
await preferences.clear();

    I think this is what you need
