class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('GestureDetector Example'),
        ),
        body: Center(
          child: GestureDetector(
            onTap: () {
              // 解雇container的操作
              print('解雇container');
            },
            child: Container(
              width: 200,
              height: 200,
              color: Colors.blue,
              child: Center(
                child: Text(
                  'Container',
                  style: TextStyle(
                    fontSize: 24,
                    color: Colors.white,
                  ),
                ),
              ),
            ),
