# ValueSelectable

![image](https://github.com/Flutterando/value_selectable/blob/main/assets/image.png?raw=true)

A Flutter package that provides computed values for `ValueNotifier`, inspired by the Selectors from Recoil.

## Overview

This package includes two main classes:

- `ValueSelector`: Computes a synchronous value based on a given scope.

These classes allow you to create computed values that automatically update when their dependencies change, providing a reactive programming model similar to Recoil selectors.

## Features

- Reactive computation of values based on dependencies.

- Synchronous and asynchronous selectors.

- Automatic updates when dependencies change.

- Easy integration with Flutter's ValueNotifier.

## Installation

Add the following to your `pubspec.yaml`:

```

flutter pub add value_selectable

```

## Usage

### ValueSelector

Computes a synchronous value based on a given scope:

```dart

import 'package:flutter/widgets.dart';

import 'package:value_selectable/value_selectable.dart';

void main() {

  final valueNotifier = ValueNotifier(1);

  final selector = ValueSelector((get) => get(valueNotifier) + 1);

  print(selector.value); // Outputs: 2

  valueNotifier.value = 2;

  print(selector.value); // Outputs: 3

}

```
