flutter -如何在复选框值更改时禁用/只读特定的文本输入字段？

class MyCheckboxTextField extends StatefulWidget {
  @override
  _MyCheckboxTextFieldState createState() => _MyCheckboxTextFieldState();
}

class _MyCheckboxTextFieldState extends State<MyCheckboxTextField> {
  bool isChecked = false;
  bool isTextFieldEnabled = true;

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        Checkbox(
          value: isChecked,
          onChanged: (value) {
            setState(() {
              isChecked = value;
              isTextFieldEnabled = !isChecked;
            });
          },
        ),
        TextField(
          enabled: isTextFieldEnabled,
          decoration: InputDecoration(
            labelText: 'Text Input',
          ),
        ),
      ],
    );
  }
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Checkbox and Text Field Example'),
        ),
        body: Center(
          child: MyCheckboxTextField(),
        ),
      ),
    );
  }
}
