As Flutter developers, you're probably no stranger to the need for clear, discreet user notifications. Flutter has been able to address this with the powerful feature of Toast Notifications. A toast notification allows you to display brief, auto-disappearing messages to the user.
Let's turn your Flutter app into a communication maestro. Ready?
Generally speaking, toast notifications are simple messages that pop up on the screen. They have limited features, providing a snapshot of minimal yet essential information to the user. The beauty of toasts is their ability to dismiss themselves after a certain duration, hence not clashing with the users' application interaction.
Toast messages come in two kinds – CENTER SHORT Toast and BOTTOM LONG Toast, depending on the display position and duration on the screen.
The best part? Incorporating flutter toast notifications in your apps is quite straightforward!
Before we dive into the code necessary for implementing toast notifications in Flutter, we need to set up our environment. This involves installing the Flutter SDK on your machine and setting up your preferred IDE (VS Code, Android Studio, etc.).
One essential step is to integrate the FlutterToast plugin into your app.
The fluttertoast plugin brings the functionality required to create toast messages in your Flutter app. First, you need to add this plugin as a dependency. Navigate to your Flutter project directory and look for a file called pubspec.yaml. This YAML file is where you list the dependencies for your project. Here, add the fluttertoast dependency.
1 // Adding fluttertoast plugin to your app 2 dependencies: 3 flutter: 4 sdk: flutter 5 fluttertoast: ^8.2.2 6
Now, inside your Dart file, import the FlutterToast package like so:
1 // Importing fluttertoast 2 import 'package:fluttertoast/fluttertoast.dart'; 3
Done with the prep work? Now your Flutter app is ready to incorporate toast notifications!
Nothing beats a leisurely stroll through the code park, right? Let's work through implementing a toast notification in your Flutter application step by step!
In Flutter, each dart file is executed starting from the void main() => runApp(MyApp()); function. The MyApp class extends the StatelessWidget, which is where we return a MaterialApp widget.
Below is an example of how we can mold our "toasts" within the MyHomePage widget in our class MyApp.
We'll be creating a toast inside the onPressed method of a FlatButton Widget. The onPressed method gets triggered when the user taps the button, making it an ideal place to display our toast.
1 // void main Function 2 void main() { 3 runApp(MyApp()); 4 } 5 6 class MyApp extends StatelessWidget { 7 @override 8 Widget build(BuildContext context) { 9 return MaterialApp( 10 home: MyHomePage(), 11 ); 12 } 13 } 14 15 class MyHomePage extends StatefulWidget { 16 @override 17 _MyHomePageState createState() => _MyHomePageState(); 18 } 19 20 class _MyHomePageState extends State<MyHomePage> { 21 22 @override 23 Widget build(BuildContext context) { 24 return Scaffold( 25 appBar: AppBar(), 26 body: Center( 27 child: FlatButton( 28 child: Text('Show Toast'), 29 onPressed: () { 30 Fluttertoast.showToast( 31 msg: "This is a Center Short Toast", 32 toastLength: Toast.LENGTH_SHORT, 33 gravity: ToastGravity.CENTER, 34 ); 35 }, 36 ), 37 ), 38 ); 39 } 40 } 41
The toast.showToast() function is called on a button press. Notice how this method gives us full control over our toast message properties, such as duration (toastLength) and position (gravity).
When using toast notifications in Flutter, developers obtain complete power over notification customization. You can change the color, size, and gravity of the toast message based on the requirements.
Ensure you set the desired properties of the showToast function so your messages match the aesthetics and purpose of your Flutter application.
See the function below, which displays a toast with a background color of blue and text color of white for 4 seconds at the center of the screen.
1 //Cusomisation of a toast notification 2 3 Fluttertoast.showToast( 4 msg: "This is a Center Short Toast", 5 toastLength: Toast.LENGTH_SHORT, 6 gravity: ToastGravity.CENTER, 7 timeInSecForIosWeb: 4, // only used in case of iOS 8 backgroundColor: Colors.blue, 9 textColor: Colors.white, 10 fontSize: 16.0 11 ); 12
Throughout this exercise, remember, the aim is to keep toast messages useful yet non-intrusive, hence enhancing your app experience!
As much as we love showing off our latest Flutter toast notifications, it's crucial not to let one tiny bread crumb ruin the soup. Let's ponder some do's and don'ts to get the most out of our toasts.
Toast notifications can be a powerful asset to your Flutter application. However, haphazardly implemented toast messages can bring about a poor user experience. As a rule of thumb, toasts with limited features should only be employed to display non-critical, context-less information. For more complex or serious messaging, alternatives such as dialog boxes might be a better way.
Remember that the contexts in which toasts are employed should be relevant. A toast message with news that someone has liked your post? Perfect. A toast notification letting users know their password doesn't meet the criteria? Probably not such a great use - a direct error message would be much more user-friendly.
From user sign-ups, messages sent, and likes received, to guiding users interactively through your Flutter app, toast notifications have numerous potential use-cases. They offer a unique opportunity to provide users with discrete updates, enhancing the user experience in subtle yet profound ways.
Like any tool or widget in a developer's toolbelt, understanding the possibilities and limitations of Flutter toast notifications is vital. They can't handle user feedback like a dialog or bear the load of sharing complex data. Yet, toasts excel at their specialty - delivering precise, bite-sized information with grace and finesse.
The careful application of toast messages in your Flutter app could give you an edge in creating intuitive, interactive, user-centric applications.
Just like hot toast doesn't stay hot for long, toast notifications appear for a duration only to disappear to make way for the user to continue their interaction with the app unhindered. The temporary and lightweight nature of Flutter toast notifications makes them excellent for delivering secondary information to users.
We began with fundamentals, moved onto creating a toast alert, and ended with best practices. Hopefully, you're now ready to spruce up your Flutter applications with tailored, user-friendly toast messages!
Through utilizing flutter toast notifications, you have a nuanced and less intrusive way to interact with your user without breaking their engagement. It's subtle, it's neat, and it can be exactly what you need to provide that "extra something" in user experience.
Creating a user-friendly app that provides clear, concise messages at the right moment is a critical aspect of user experience design. Toast Notifications in Flutter are a light, smart, and flexible way to communicate with your users without hampering their app experience.
From user feedback, tips on using the app, to minor app updates - the applications of Flutter toast notifications are endless. Whether you're building a social media app or a productivity tool, toast notifications can help you gently speak to your users without shouting.
Remember, the key to a good toast notification Flutter app is to keep toast messages impactful, straight to the point, and relevant. A well-crafted toast message enhances the user experience and subtly brings attention to what matters most - whether it's an achievement, a greeting, or a gentle bump to explore more.
This journey of unboxing the emblematic Flutter toast notifications is like leaning onto a virtual bar, raising your glass, and sharing a toast of successes and highlights. We hope now you are well-equipped to use this subtle art of messaging to impress your users!
As you set out to experiment with Flutter toast notifications, remember the potent power of its simplicity. Here's to more cogent, user-friendly Flutter apps, one toast at a time!
