TextView and Button Example in Flutter

To display “Hello, good morning” text when a button is clicked in Flutter, you can use StatefulWidget to update the UI. Here’s a simple example:

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: GreetingScreen(),
    );
  }
}

class GreetingScreen extends StatefulWidget {
  @override
  _GreetingScreenState createState() => _GreetingScreenState();
}

class _GreetingScreenState extends State<GreetingScreen> {
  String greetingText = "";

  void showGreeting() {
    setState(() {
      greetingText = "Hello, good morning";
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Greeting App')),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text(
              greetingText,
              style: TextStyle(fontSize: 24),
            ),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: showGreeting,
              child: Text('Click Me'),
            ),
          ],
        ),
      ),
    );
  }
}
