How To Use Flutter TextButton OnPressed [Flutter Easy Guide]

In this tutorial, we’ll learn how to properly use Flutter textButton onPressed with the help of an easy Flutter example.

Introduction: Flutter TextButton OnPressed

As the name suggests, it’s used to trigger some actions after the text 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 TextButton OnPressed (Easy Example Code)

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

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

As you can see that we have specified the snackbar inside the onPressed function. We also have passed the Flutter text widget to the child constructor of textButton class to make the button looks a bit professional.

Let’s now press the button and see if we get the snackbar on our screen.

You can see here that after the button was pressed, the onPressed function was triggered and as a result, the snackbar widget was shown on the screen.

You can specify any action in the body of onPressed function, like navigation to some other screen, validation, addition etc.

So this is how we can use the Flutter textButton onPressed with ease. Hope you like this post.

Don’t hesitate to ask if you still have any questions related to the implementation of Flutter textButton onPressed function. I’d be more than happy to answer all your questions.

Below section includes the complete source code of the above implemented Flutter textButton onPressed function.

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