在Flutter中可以重用TextEditingController吗？

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('TextEditingController Demo')),
        body: MyForm(),
      ),
    );
  }
}

class MyForm extends StatefulWidget {
  @override
  _MyFormState createState() => _MyFormState();
}

class _MyFormState extends State<MyForm> {
  final TextEditingController _controller = TextEditingController();

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        TextField(
          controller: _controller,
          decoration: InputDecoration(labelText: 'Enter text'),
        ),
        SizedBox(height: 20),
        ElevatedButton(
          onPressed: () {
            print('Text entered: ${_controller.text}');
          },
          child: Text('Submit'),
        ),
      ],
    );
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }
}

class MyForm extends StatefulWidget {
  @override
  _MyFormState createState() => _MyFormState();
}

class _MyFormState extends State<MyForm> {
  final TextEditingController _controller1 = TextEditingController();
  final TextEditingController _controller2 = TextEditingController();

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        TextField(
          controller: _controller1,
          decoration: InputDecoration(labelText: 'Enter text 1'),
        ),
        TextField(
          controller: _controller2,
          decoration: InputDecoration(labelText: 'Enter text 2'),
        ),
        ElevatedButton(
          onPressed: () {
            print('Text 1 entered: ${_controller1.text}');
            print('Text 2 entered: ${_controller2.text}');
          },
          child: Text('Submit'),
        ),
      ],
    );
  }

  @override
  void dispose() {
    _controller1.dispose();
    _controller2.dispose();
    super.dispose();
  }
}
