Flutter sharedpreferences get all keys

Using SharedPreferences to Get All Keys in Flutter

SharedPreferences is a key-value storage plugin that allows you to persist data in a Flutter application. To get all keys stored in SharedPreferences, you can follow these steps:

1. Import the required packages:

      
        import 'package:shared_preferences/shared_preferences.dart';
      
    

2. Get an instance of SharedPreferences:

      
        SharedPreferences prefs = await SharedPreferences.getInstance();
      
    

3. Retrieve all keys:

      
        Set keys = prefs.getKeys();
      
    

4. Use the keys as desired:

      
        keys.forEach((key) {
          var value = prefs.get(key);
          print('Key: $key, Value: $value');
        });
      
    

In the example above, we first import the necessary package ‘shared_preferences’. Then, we get an instance of SharedPreferences using the ‘getInstance()’ method. After that, we retrieve all keys using the ‘getKeys()’ method, which returns a Set of strings representing the keys. Finally, we loop through the keys and fetch the corresponding values using the ‘get(key)’ method.

Feel free to replace the ‘print’ statement with any other code to use the keys and values as per your requirements.
