1、借鉴iOS NotificationCenter实现消息广播，源码简洁明了只有80余行。

2、简单4步实现消息的监听、广播、接收、销毁。

3、除了简单易用还是简单易用

Use this package as a library

1. Depend on it

Add this to your package's pubspec.yaml file:

dependencies: ksnotification: last

2. Install it

You can install packages from the command line:

with Flutter:

$ flutter pub get

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

3. Import it

Now in your Dart code, you can use:

const String _kPriceChange = 'kPriceChange';

class _KSPackagesManagerPageState extends State<KSPackagesManagerPage> {
  String _price = '';

  @override
  void initState() {
    super.initState();
    /*1、添加监听*/
    KSNotificationCenter.shard()
        .addListener(_kPriceChange, _priceChangeCallback);
  }

  /*2、监听回调*/
  void _priceChangeCallback(dynamic price) {
    setState(() {
      _price = price;
    });
  }

  @override
  void dispose() {
    /*4、移除监听*/
    KSNotificationCenter.shard().removeListener(_kPriceChange, _priceChangeCallback);
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    String iphone_price = '3889元';
    return Scaffold(
      appBar: KSAppBar.ks_init(title: widget.pageTitle),
      body: ListView(
        children: <Widget>[
          KSListTile.ks_init(title: _price, onTap: null),
          KSListTile.ks_init(
              title: '价格修改为（${iphone_price}）',
              onTap: () {
                /*3、发送消息*/
                KSNotificationCenter.shard().post(iphone_price, _kPriceChange);
              }),
        ],
      ),
    );
  }
}
