In this Flutter post, we’ll learn how to properly use Flutter elevated button onPressed with the help of an easy Flutter example for practical demonstration.
A step by step explanation will be provided on the onPressed function of Flutter elevated button so you can have an in-depth idea of how to implement it.
So let’s not wait anymore and dive right into it.
What is Flutter Elevated Button OnPressed?
As the name suggests, it’s used to trigger some actions after the elevated button is clicked by the user. We’ll be using a proper example to demonstrate how you can use it.
So let’s get right into its practical implementation.
Implementing Flutter Elevated Button OnPressed (Easy Example Code)
We first have to define a simple Flutter elevated button widget. Then we will use its required onPressed constructor which takes a function. We can specify any action we want in the body of that function.
To demonstrate how it works, we’ll be using a Flutter snackbar widget inside that function’s body. So whenever the user clicks on the elevated button, the snackbar widget will appear on the screen. See below code in which this theory is practically implemented.
ElevatedButton( onPressed: () { ScaffoldMessenger.of(context).showSnackBar(SnackBar( content: Text('Elevated button is pressed'))); }, child: Text('Elevated button OnPressed'))


Flutter Elevated Button OnPressed Implementation Source Code
import 'package:flutter/material.dart'; void main() { runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({Key? key}) : super(key: key); @override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false, home: Homepage(), ); } } class Homepage extends StatefulWidget { @override State<Homepage> createState() => _HomepageState(); } class _HomepageState extends State<Homepage> { @override Widget build(BuildContext context) { return SafeArea( child: Scaffold( body: Center( child: ElevatedButton( onPressed: () { ScaffoldMessenger.of(context).showSnackBar(SnackBar( content: Text('Elevated button is pressed'))); }, child: Text('Elevated button OnPressed'))))); } }
Conclusion
As a conclusion, hope you now have an in-depth knowledge of how to properly use Flutter elevated button onPressed. I’d love to see you share your valuable thoughts on this post. Thank you for reading this post.
