    var pref = await SecureSharedPref.getInstance();
    await pref.putString("StringEncrypted", "This is my first string test", true);
    await pref.putInt("key", 100, true);
    await pref.putMap("mapKey", {"Hello":true}, true);
    await pref.putDouble("doubleKey", 20.32, true);
    await pref.putBool("boolKey", true, true);
    await pref.putStringList("listKey", ["S","K"], true);

2. Fetch :
