Flutter 监听应用状态

混淆 WidgetsBindingObserver

@override
void initState() {

// TODO: implement initState
WidgetsBinding.instance.addObserver(this);
super.initState();

}

@override
void dispose() {

// TODO: implement dispose
WidgetsBinding.instance.removeObserver(this);
super.dispose();

}

@override
void didChangeAppLifecycleState(AppLifecycleState state) {

// TODO: implement didChangeAppLifecycleState

print('状态$state');
super.didChangeAppLifecycleState(state);

}
