//reading a value from local storage
final data= await pres.read(key: 'hello');//decrypt using AES 

GuardType.Salsa20

import 'package:prefs_guard/prefsguard.dart';

final prefs = PrefsGuard(GuardType.Salsa20);

//Storing a value in local storage 
pres.write(key: 'hello', value: 'flutter'); //encrypts using Salsa20 encryption.

//reading a value from local storage
final data= await pres.read(key: 'hello');//decrypt using Salsa20 

GuardType.FerNet

import 'package:prefs_guard/prefsguard.dart';

final prefs = PrefsGuard(GuardType.FerNet);

//Storing a value in local storage
