import 'package:flutter_keyboard_visibility/flutter_keyboard_visibility.dart';

class MyPage extends StatefulWidget {
  @override
  _MyPageState createState() => _MyPageState();
}

class _MyPageState extends State<MyPage> {
  bool isKeyboardVisible = false;

  @override
  void initState() {
    super.initState();
    KeyboardVisibility.onChange.listen((bool visible) {
      setState(() {
        isKeyboardVisible = visible;
      });
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('My Page'),
      ),
      body: Column(
        children: [
          TextField(
            decoration: InputDecoration(
              labelText: 'Enter text',
            ),
          ),
          SizedBox(height: 16),
          Visibility(
            visible: isKeyboardVisible,
            child: Text('Keyboard is visible'),
          ),
        ],
      ),
    );
  }
}
