Introduction: Flutter OutlinedButton OnPressed

As the name suggests, it’s used to trigger some actions after the outlined button is clicked by the user. We’ll be using a proper example to demonstrate how we can use it.

So let’s get right into its practical implementation.

Implementing Flutter OutlinedButton OnPressed (Easy Example Code)

We first have to define a simple Flutter outlinedButton 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 outlinedButton, the snackbar widget will appear on the screen. See below code in which this theory is practically implemented.

OutlinedButton(
               onPressed: () {
               ScaffoldMessenger.of(context).showSnackBar(SnackBar(
                          content: Text('Outlined button is pressed')));
                    },
               child: Text('Outlined button OnPressed'))

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: OutlinedButton(
                    onPressed: () {
                      ScaffoldMessenger.of(context).showSnackBar(SnackBar(
                          content: Text('Outlined button is pressed')));
                    },
                    child: Text('Outlined button OnPressed')))));
  }
}
