Introduction:

Toast messages are a common way to provide temporary, non-intrusive notifications or feedback to users in mobile apps. In Flutter, you can display toast messages to provide important information, success messages, error notifications, or other types of feedback. Toast messages typically appear as a small pop-up at the bottom of the screen and automatically disappear after a short duration. In this step-by-step guide, you will learn how to show toast messages in Flutter. By following this tutorial, you will be able to implement toast messages using the Fluttertoast package and customize their appearance and behavior.

Content:

1. Set up a new Flutter project:

Ensure that you have Flutter installed and set up on your machine. Create a new Flutter project using the following command in your terminal:

Copy Code


flutter create toast_app

2. Add the Fluttertoast package:

Open the pubspec.yaml file in your Flutter project and add the fluttertoast package as a dependency:

Copy Code


dependencies:
  fluttertoast: ^8.0.8

Save the file and run the following command in your terminal to fetch the package:

Copy Code


flutter pub get

3. Import the Fluttertoast package:

In the Dart file where you want to show the toast message, import the fluttertoast package:

Copy Code


import 'package:fluttertoast/fluttertoast.dart';

4. Show a toast message:

To display a toast message, call the Fluttertoast.showToast() method with the desired parameters. Here’s an example:

Copy Code


Fluttertoast.showToast(
  msg: 'This is a toast message',
  toastLength: Toast.LENGTH_SHORT,
  gravity: ToastGravity.BOTTOM,
  backgroundColor: Colors.black.withOpacity(0.8),
  textColor: Colors.white,
);

5. Customize the toast message:

You can customize the appearance and behavior of the toast message by specifying different parameters. For example, you can set the toastLength to Toast.LENGTH_LONG for a longer duration, modify the gravity to position the toast at the top, center, or bottom of the screen, change the backgroundColor and textColor to match your app’s design, and more.

Sample Code:

Copy Code


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

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Toast Example',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Toast Example'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            showToast();
          },
          child: Text('Show Toast'),
        ),
      ),
    );
  }

  void showToast() {
    Fluttertoast.showToast(
      
      msg: 'Hello this is a Toast! meassege,',
      toastLength: Toast.LENGTH_SHORT,
      gravity: ToastGravity.BOTTOM,
      backgroundColor: Colors.black.withOpacity(0.8),
      textColor: Colors.white,
    );
  }
}

Output:
