  Widget build(BuildContext context) {
    Switch sw = Switch(
      value: flag,
      onChanged: (value) {
        setState(() {
          flag = value;
        });
      },
      activeColor: Colors.blue,
      activeTrackColor:Colors.green ,
      activeThumbImage: NetworkImage("https://pic.rmb.bdstatic.com/bjh/news/49fa0be5e4ab397fe5a04412d5cfe3f6.png"),
    );

    return Scaffold(
      appBar: AppBar(title: Text("Flex"), centerTitle: true),
      body: sw,
    );
  }
}

SwitchListTile

class MyState extends State {
  bool flag = false;

  @override
  Widget build(BuildContext context) {
    Column column = Column(
      children: [
        SwitchListTile(
          value: false,
          onChanged: (value) {},
          title: Text("6:00"),
          subtitle: Text("周一至周五响铃"),
        ),
        SwitchListTile(
          value: false,
          onChanged: (value) {},
          title: Text("10:00"),
          subtitle: Text("星期六、日响铃"),
        ),
      ],
    );

    return Scaffold(
      appBar: AppBar(title: Text("SwitchListTile"), centerTitle: true),
      body: column,
    );
  }
}
