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 https://flutter.dev/docs/get-started/install.
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."
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:
dependencies: flutter: 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';
You can now use the Fluttertoast.showToast()
method to display a toast message. Here's how you can do it:
Fluttertoast.showToast( 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: Colors.black, // Background color of the toast textColor: Colors.white, // Text color of the toast fontSize: 16.0, // Font size of the toast text );
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()
.
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.
import 'package:flutter/material.dart';
import 'package:fluttertoast/fluttertoast.dart'; void main() { runApp(MaterialApp( home: TextColorChanger(), )); } class TextColorChanger extends StatefulWidget { @override _TextColorChangerState createState() => _TextColorChangerState(); } class _TextColorChangerState extends State { Color textColor = Colors.black; // Initialize with the default text color. bool isTextColorRed = true; void toggleTextColor() { setState(() { // Toggle the text color between red and blue. if (isTextColorRed) { textColor = Colors.blue; } else { textColor = Colors.red; } isTextColorRed = !isTextColorRed; }); // Display a toast message when the text color is toggled Fluttertoast.showToast( msg: isTextColorRed ? "Text color is now red" : "Text color is now blue", toastLength: Toast.LENGTH_SHORT, gravity: ToastGravity.BOTTOM, timeInSecForIosWeb: 1, backgroundColor: Colors.black, textColor: Colors.white, fontSize: 16.0, ); } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar(title: Text('Toggle Text Color')), body: Center( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: [ AnimatedDefaultTextStyle( style: TextStyle( color: textColor, fontSize: 24, ), duration: Duration(seconds: 1), child: Text('Toggle Me'), ), SizedBox(height: 20), ElevatedButton( onPressed: () { toggleTextColor(); }, child: Text('Toggle Text Color'), ), ], ), ), ); } }
When user clicks on Toggle Text Color, a toast message will gets displayed based on flag isTextColorRed
In Flutter, a toast message is a brief, non-intrusive message that pops up at the bottom of the screen to convey information to the user. Toast messages are typically used to display short notifications, alerts, or confirmations.
To create a toast message in a Flutter app, follow these steps:
Yes, Fluttertoast provides various customization options for toast messages. You can set properties like duration, gravity (position), backgroundColor, text color, and more to tailor the appearance and behavior of toast messages to your specific requirements.
Certainly! You can create toast messages with various styles and themes in Flutter. By customizing the toast messages background color, text color, and other visual elements, you can ensure that the toast messages align with your apps design and branding.
