在flutter中有没有可能有像这样的小部件

import 'package:flutter/material.dart';

class CustomWidget extends StatefulWidget {
  @override
  _CustomWidgetState createState() => _CustomWidgetState();
}

class _CustomWidgetState extends State<CustomWidget> {
  bool _isPressed = false;

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        setState(() {
          _isPressed = !_isPressed;
        });
      },
      child: Container(
        width: 100,
        height: 100,
        color: _isPressed ? Colors.blue : Colors.red,
        child: Center(
          child: Text(
            _isPressed ? 'Pressed' : 'Not Pressed',
            style: TextStyle(
              fontSize: 20,
              color: Colors.white,
            ),
          ),
        ),
      ),
    );
  }
}
