#Listenable

Listenable help you to manage Flutter widgets and state synchronization by leveraging the [ValueListenable] class. You will annotate you models and it will generate the required code for your models to be listenable by a ListenableBuilder widget.

import 'package:listenable/listenable.dart';

part 'counters.g.dart';

class Counter = _Counter with _Counter$Listenable;

@ListenableModel()
abstract class _Counter {
  @ListenableProperty()
  final String name;
  @ListenableProperty(updatesModel: false)
  int _count = 0;

  _Counter(this.name);

  void increment() {
    _count++;
  }

  void decrement() {
    _count--;
  }
}

Rebuild you widgets using the flutter existing widgets, you don't need any additional library

import 'package:flutter/widgets.dart';

class CounterWidget extends StatelessWidget {
  final Counter _counter = Counter('MyCounter');
  @override
  Widget build(BuildContext context) {
    return ValueListenableBuilder<int>(
      valueListenable: _counter.countListenable,
      builder: (context, count, _) => Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: <Widget>[
          Text(
            '[$count]',
            style: TextStyle(
                fontSize: 35, fontWeight: FontWeight.bold),
          ),
          Text('${_counter.name}'),
        ],
