How to Use OKToast in Your Flutter Application

Oct 31, 2023 | Programming

Welcome to your one-stop guide for implementing the OKToast library in Flutter! This pure Dart toast library allows you to create customizable toast notifications effortlessly. Whether you want to display messages or interactive widgets, OKToast is your go-to solution.

Why Use OKToast?

Toasts offer a great way to provide feedback to users without interrupting their current task. The OKToast library brings null-safety and a variety of customizable styles to your Flutter applications. Let’s get started!

Installation and Setup

Follow these steps to install and configure OKToast in your Flutter app:

  • Step 1: Add the library

    Open your pubspec.yaml file and add the OKToast package:

    flutter pub add oktoast
  • Step 2: Import the library

    In your Dart file, import the OKToast package:

    import 'package:oktoast/oktoast.dart';
  • Step 3: Wrap your app with OKToast

    Use the OKToast widget to wrap your MaterialApp:

    OKToast(
          child: MaterialApp(),
        );
  • Step 4: Call showToast

    Create toasts using:

    showToast('Your message here!');

Explaining Toast Wrapping

Imagine you’re designing a beautiful cafe. To make sure every customer feels welcome and served without obstruction, you design different seating arrangements. In programming, wrapping your MaterialApp with OKToast ensures that all toast notifications can be displayed in front of other widgets, just like strategic seating creates an inviting atmosphere. Additionally, this caching of context allows you to call toasts from anywhere in your app, similar to having a server at your beck and call!

Customizing OKToast

OKToast allows for extensive customization to suit your app’s needs. Below are some key properties:

  • textStyle: Set the style of your text.
  • backgroundColor: Choose the background color of your toast.
  • duration: Set how long the toast should be displayed.

Example Code

Here is a complete example to visualize the implementation:


import 'package:flutter/material.dart';
import 'package:oktoast/oktoast.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return OKToast(
      child: MaterialApp(
        title: 'Flutter Demo',
        home: MyHomePage(),
      ),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
      showToast('Count: $_counter', duration: Duration(seconds: 2));
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('OKToast Example'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text('You have pushed the button this many times:'),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headline4,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: Icon(Icons.add),
      ),
    );
  }
}

Troubleshooting Common Issues

While using OKToast, you may run into some issues. Here are a few troubleshooting tips:

  • If you encounter the error “No MediaQuery widget found”, ensure you’ve wrapped your MaterialApp with OKToast as described in the usage section.
