Notice: You're viewing an old version of the Nylo documentation.
Consider upgrading your project to Nylo 3.x.



In Nylo you can save data to the users device using the NyStorage class.

This uses the flutter_secure_storage package to save and retrieve data.

Store values

To store values, you can use the below helper.

import 'package:nylo_support/helpers/helper.dart';
..."", "10");

Retrieve values

To retrieve values, you can use the below helper.

import 'package:nylo_support/helpers/helper.dart';

// Default
String coins = await""); // 10

// String
String coins = await<String>(""); // 10

// Integer
int coins = await<int>(""); // 10

// double
double coins = await<double>(""); // 10.00

Introduction to storable models

Storable models are useful for storing small sized data to the users devices. It can be helpful way to store the users progress in a game, coins or even their api token.

Here's a model that extends the Storable class.

class User extends Storable {
  String token;
  String username;
  String favouriteCity; 

  User({this.token, this.username, this.favouriteCity});

  toStorage() => {
      "token": this.token, 
      "username": this.username, 
      "favourite_city": this.favouriteCity

  fromStorage(dynamic data) {
    this.token = data['token'];
    this.username = data['username'];
    this.favouriteCity = data['favourite_city'];

After extending the Storable class, you then need to override the toStorage() and fromStorage methods.

  • toStorage() - Creates the payload to be stored.

  • fromStorage(dynamic data) - This will create the model from the data payload, the keys should match the toStorage() method.

Saving a Storable model

To save a Storable model, you can use the below helper.

import 'package:nylo_support/helpers/helper.dart';

User user = new User();
user.username = "Anthony";

String key = "";

// saves to storage;

// or, user);

Retrieve a Storable model

To retrieve a Storable model, you can use the below helper.

import 'package:nylo_support/helpers/helper.dart';
String key = "";

User user = await, model: new User());
print(user.username); // Anthony
