On the screen, the user enters a message in the field and when the button is clicked, pop() fires.
How can I pass the data from the field to the previous screen and display it? For implementation, I need to use pop()
Screen with TextField:

```js
// text controller for message input
  TextEditingController textController = TextEditingController();

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

  // go to result screen
  void getResult() {
    Navigator.pop(context, textController.text);
  }

  ElevatedButton(
                  onPressed: getResult, child: const Text('Display result'))
```

ResultScreen:

```js
class ResultScreen extends StatefulWidget {

  @override
  State<ResultScreen> createState() => _ResultScreenState();
}

class _ResultScreenState extends State<ResultScreen> {
  @override
  Widget build(BuildContext context) {
    // navigation to text_screen
    void _navToTextScreen() {
      Navigator.push(
        context,
        MaterialPageRoute(builder: (context) => const TextScreen()),
      );
    }

    return Scaffold(
      appBar: AppBar(
        title: const Text('Results'),
      ),
      body: Center(
          child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
          ElevatedButton(
            onPressed: _navToTextScreen,
            child: const Text('Enter data'),
          ),
          const SizedBox(
            height: 50
          ),
          Text('User Message:'),
          const SizedBox(
            height: 20
          ),
        ],
      )),
    );
  }
}
```
