eazy state

Eazy State Management #
A lightweight and straightforward state management solution for Flutter applications, designed to manage and update UI state efficiently without the overhead of more complex state management tools.
Features #

EazyState: A class to manage a single piece of state with a stream-based approach.
EazyBuilder: A widget that rebuilds itself when the state changes, using the power of StreamBuilder.
Minimal API: Easy to understand and integrate into any Flutter project.

Installation 💻 #
Add the following dependency to your pubspec.yaml file:
dependencies:
eazy_state: ^0.1.1

Then, run flutter pub get to install the package.
Usage #
EazyState #
EazyState is a class that holds a value and provides a stream for updates. It allows you to manage state and notify listeners about changes.
import 'package:eazy_state/eazy_state.dart';

final counterState = EazyState(0);

void incrementCounter() {
counterState.value += 1;
}

EazyBuilder #
EazyBuilder is a widget that rebuilds when the EazyState value changes. It listens to the EazyState stream and rebuilds the UI based on the current state value.
import 'package:flutter/widgets.dart';
import 'package:eazy_state/eazy_state.dart';

class CounterWidget extends StatelessWidget {
final EazyState<int> counterState;

const CounterWidget({required this.counterState});

@override
Widget build(BuildContext context) {
return EazyBuilder<int>(
state: counterState,
builder: (context, count) {
return Text('$count');
},
);
}
}

Examples #
Example 1: Using Same State in Multiple Places #
final counterState = EazyState(10.0);

class MyEazyPage extends StatelessWidget {
const MyEazyPage({super.key});

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
title: const Text("Flutter Demo Home Page"),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
const Text('You have pushed the button this many times:'),
EazyBuilder(
state: counterState,
builder: (context, count) {
return Text(
'$count',
style: Theme.of(context).textTheme.headlineMedium,
);
},
),
ElevatedButton(
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (_) => const MyEazyPageSecond(),
),
);
},
child: const Text("Move"),
),
],
),
),
floatingActionButton: FloatingActionButton(
onPressed: () => counterState.value += 1,
tooltip: 'Increment',
child: const Icon(Icons.add),
),
);
}
}

Example 2: Using State in Single Screen #
class MyEazyPage extends StatefulWidget {
const MyEazyPage({super.key});

@override
State<MyEazyPage> createState() => _MyEazyPageState();
}

class _MyEazyPageState extends State<MyEazyPage> {
final counterState = EazyState(10);

@override
void dispose() {
counterState.dispose();
super.dispose();
}

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
title: const Text('Flutter Demo Home Page'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
const Text('You have pushed the button this many times:'),
EazyBuilder(
state: counterState,
builder: (context, count) {
return Text(
'$count',
style: Theme.of(context).textTheme.headlineMedium,
);
},
),
ElevatedButton(
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (_) => const MyEazyPageSecond(),
),
);
},
child: const Text('Move'),
),
],
),
),
floatingActionButton: FloatingActionButton(
onPressed: () => counterState.value += 1,
tooltip: 'Increment',
child: const Icon(Icons.add),
),
);
}
