CacheX for Flutter #

A feasible caching library for Flutter. Save any encrypted string.

Inspired by CacheX for Android

How does it work ? #

Caching is just a simple key-value pair data saving procedure. CacheX follows the same approach. CacheX uses SharedPreference as storage for caching data. Since we really can't just save the original data because of security issues. CacheX uses AES encryption & decryption behind the scene when you are caching data or fetching data from the cache.

Getting Started #

First you have to add the package dependency in pubspec.yml

cache_x: ^latest

Get the version from pub.flutter-io.cn

In the main Function of your Flutter app #

void main() async {
    WidgetsFlutterBinding.ensureInitialized();

    // Initialize 128byte password (16 character)
    String password = 'CBoaDQIQAgceGg8d';

    // Initialize CacheX with the password
    await CacheXCore().init(password);

    // Do your apps essential works

    // Then anywhere in your app use it to save string
    print(await CacheXCore.instance.saveData('ft1', 'Tanvir'));
    // Get String
    print(await CacheXCore.instance.getData('ft1'));
}

CacheXCore.instance.saveData(String key, String value) will return Future<bool> so you have to use await to get the result of it or there any exception will throw exception.

CacheXCore.instance.getData(String key) will return Future<String> so to get the string you have to use await and it will throw exception if there any.
