4.2、SwitchListTile的demo

class _SwitchFulState extends State<SwitchFul> {
  var eatState = false;
  var sleepState = false;
  var hitState = false;

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          appBar: AppBar(
            title: Text("SwitchListTile学习"),
          ),
          body: Center(
            child: Column(
              children: [
                SwitchListTile(
                  value: eatState,
                  onChanged: (value) {
                    setState(() {
                      eatState = value;
                    });

                ),
                SwitchListTile(
                  value: hitState,
                  onChanged: (value) {
                    setState(() {
                      hitState = value;
                    });

4.3、CupertinoSwitch的demo

class _SwitchFulState extends State<SwitchFul> {
  var eatState = false;
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          appBar: AppBar(
