Usage

Basic Usage

import 'package:shared_pref_pro/shared_pref_pro.dart';

final sharedPref = SharedPrefPro.instance;

// Save a value
await sharedPref.save('username', 'john_doe');

// Get a value
String? username = await sharedPref.get<String>('username');

Smart Expiring Cache (New! 🚀)

You can save values that automatically "expire" after a certain duration. This is perfect for tokens, OTPs, or temporary session data.

// Save a token that expires in 2 hours
await sharedPref.save(
  'auth_token', 
  'secret_token_123', 
  expireIn: Duration(hours: 2),
);

// After 2 hours, this will return null and automatically delete the key from storage
String? token = await sharedPref.get<String>('auth_token');

Complex Objects (JSON)

Map<String, dynamic> user = {'id': 1, 'name': 'John'};

// Save Map
await sharedPref.save('user_data', user);

// Get Map
Map<String, dynamic>? storedUser = await sharedPref.get<Map<String, dynamic>>('user_data');
