app_lifecycle 0.0.1 app_lifecycle: ^0.0.1 copied to clipboard
Native lifecycle functions that support iOS and Android, unlike WidgetBindings that comes with flutter.
app_lifecycle #
- 原生的生命周期函数,支持 iOS 和 Android,不同于 flutter 中自带的 WidgetBindings
- WidgetBindings 主要是指跳出 flutter UIController/Activity事件,而本插件是整个 App 级别的。
- Android 没有激活或者取消激活状态。
demo #
import 'package:app_lifecycle/app_lifecycle.dart';

void main() {
runApp(MyApp());

}
class _MyAppState extends State<MyApp> {
List<String> eventStrings = ['first null'];
@override
void initState() {
super.initState();
AppLifecycle.lifeCycleStream.listen((event) {
print('event = $event');
eventStrings.add("${DateTime.now()} --- ${event.shortStr}");
setState(() {});
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: ListView.separated(
itemCount: eventStrings.length,
separatorBuilder: (context, index) => Container(
height: 0.3,
color: Colors.grey,

itemBuilder: (context, index) {
return Container(
height: 30,
child: Center(child: Text('${eventStrings[index]}')),
