Usage

Save :

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

await pref.getString("StringEncrypted", isEncrypted: true);
await pref.getInt("key", isEncrypted: true);
await pref.getMap("mapKey", isEncrypted: true);
await pref.getDouble("doubleKey", isEncrypted: true);
await pref.getBool("boolKey",isEncrypted: true);
await pref.getStringList("listKey", isEncrypted: true);
