(WORK IN PROGRESS)

A simple state management solution inspired by Unity Atoms and built on riverpod and flutter_hooks

This is bascially a thin wrapper on top of riverpod providers that exposes some preset factory functions to generate simple providers. Is it worth it?! I dunno. Feel free to let me know if you think it's worth continuing to develop.

FYI: You can do everything this package can do directly with riverpod providers.

Features

• Void Events
• Value Events
• Pair Events (Value events with history)
• Variables (StateNotifiers with optional events)
• Constants (immutable variables)
• Void Conditions (pointless?)
• Value Conditions (reusable conditions)

Example Usage

import 'package:flutter/material.dart';
import 'package:flutter_hooks/flutter_hooks.dart';
import 'package:hooks_riverpod/hooks_riverpod.dart';
import 'package:flutter_atoms/flutter_atoms.dart';

final changedEvent = createAtomEvent<String>();
final changedHistoryEvent = createAtomPairEvent<String, String>();
final textVariable = createAtomVariable(
  'hello world',
  changedEvent: changedEvent,
  changedWithHistoryEvent: changedHistoryEvent,
);

class AtomsExample extends HookWidget {
  @override
  Widget build(BuildContext context) {
    useAtomEvent(changedEvent, (String value) {
      print('Text Updated: $value');
    });

    return Center(
      child: ElevatedButton(
        onPressed: () => context.read(changedEvent).raise('foo bar'),
        child: const Text('Update Text'),
      ),
    );
  }
}

class SomeOtherClass extends HookWidget {
  @override
  Widget build(BuildContext context) {
    final myText = useAtomVariable(textVariable);

    useAtomPairEvent(changedHistoryEvent, (String previous, String current) {
      print('Text Updated from "$previous" to "$current"');
    });

    return Center(child: Text(myText));
  }
}

Getting Started

This project is a starting point for a Dart package, a library module containing code that can be shared easily across multiple Flutter or Dart projects.
