Step 1: Set Up Your Flutter Development Environment

Before you start, make sure you have Flutter and Dart installed on your system. If you haven't already, you can follow the official Flutter installation guide at

Step 2: Create a New Flutter Project

Open your terminal and run the following commands to create a new Flutter project and navigate to its directory:

flutter create text_color_change
cd text_color_change

This will create a new Flutter project named "text_color_change."

Step 3: Add Dependencies

To create a toast, you'll need to add the 'fluttertoast' package to your Flutter project. Open your project's pubspec.yaml file and add the following dependency:

    sdk: flutter
  fluttertoast: ^8.0.8

Then run flutter pub get to fetch the package.

Step 2: Import the Package

In your Dart file where you want to use the toast, import the package:

import 'package:fluttertoast/fluttertoast.dart';

Step 4: Display a Toast Message

You can now use the Fluttertoast.showToast() method to display a toast message. Here's how you can do it:

  msg: "This is a toast message",
  toastLength: Toast.LENGTH_SHORT, // You can also use Toast.LENGTH_LONG
  gravity: ToastGravity.BOTTOM, // Position of the toast
  timeInSecForIosWeb: 1, // Duration to show the toast (in seconds)
  backgroundColor:, // Background color of the toast
  textColor: Colors.white, // Text color of the toast
  fontSize: 16.0, // Font size of the toast text

Step 5: Customizing the Toast

You can customize the toast according to your needs. For example, you can change the toast's position, duration, background color, text color, and font size by modifying the parameters of Fluttertoast.showToast().

Step 6: Show the Toast

Simply call the Fluttertoast.showToast() method to display the toast message when needed, like in response to a button press or any other user action.

That's it! You've successfully created a toast message in your Flutter app using the 'fluttertoast' package. To display different messages, just call the Fluttertoast.showToast() method with the desired message and settings.

Step 6: Final Code 

import 'package:flutter/material.dart';

import 'package:fluttertoast/fluttertoast.dart';

void main() {
    home: TextColorChanger(),

class TextColorChanger extends StatefulWidget {
  _TextColorChangerState createState() => _TextColorChangerState();

class _TextColorChangerState extends State {
  Color textColor =; // Initialize with the default text color.
  bool isTextColorRed = true;

  void toggleTextColor() {
    setState(() {
      // Toggle the text color between red and blue.
      if (isTextColorRed) {
        textColor =;
      } else {
        textColor =;
      isTextColorRed = !isTextColorRed;
    // Display a toast message when the text color is toggled
      msg: isTextColorRed ? "Text color is now red" : "Text color is now blue",
      toastLength: Toast.LENGTH_SHORT,
      gravity: ToastGravity.BOTTOM,
      timeInSecForIosWeb: 1,
      textColor: Colors.white,
      fontSize: 16.0,

  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Toggle Text Color')),
      body: Center(
        child: Column(
          children: [
              style: TextStyle(
                color: textColor,
                fontSize: 24,
              duration: Duration(seconds: 1),
              child: Text('Toggle Me'),
            SizedBox(height: 20),
              onPressed: () {
              child: Text('Toggle Text Color'),

When user clicks on Toggle Text Color, a toast message will gets displayed based on flag isTextColorRed
