Toastification is a fabulous Flutter package designed to simplify the addition of toast notifications in your applications. These notifications serve as short pop-up messages that inform users without interrupting their interactions. This blog will guide you through using Toastification, troubleshooting tips, and how to enhance your app’s user experience with toast messages.

Why Use Toastification?

The strength of Toastification lies in its ability to manage multiple toast messages simultaneously. When many notifications are triggered, they queue up instead of overlapping. Imagine you’re at a busy restaurant – each waiter (toast message) takes a number and serves you one after the other, ensuring you don’t miss important information!

Installation

To get started with Toastification in your Flutter app, follow these simple steps:

• Open your pubspec.yaml file.
• Add the following dependency:

dependencies:
  toastification: latest_version

• Run the command flutter pub get to install the package.

Basic Usage

To utilize Toastification, import the package at the top of your Dart file:

import 'package:toastification/toastification.dart';

Displaying Toasts

You can show predefined toast messages using two main methods:

• toastification.show – For predefined messages.
• toastification.showCustom – For custom messages with distinctive styles.

Displaying Messages Without Context

If you want to display messages without needing context, wrap your app widget with ToastificationWrapper:

return ToastificationWrapper(
  child: MaterialApp(),
);

Using the Show Method

Here’s how to display a simple toast message:

toastification.show(
  context: context,
  title: Text('Hello, world!'),
  autoCloseDuration: const Duration(seconds: 5),
);

In this example, a message saying “Hello, world!” will appear for five seconds. You can customize further using the provided parameters.

Using the ShowCustom Method

If you desire more control, showCustom() allows you to build a completely customized toast message:

toastification.showCustom(
  context: context,
  autoCloseDuration: const Duration(seconds: 5),
  alignment: Alignment.topRight,
  builder: (BuildContext context, ToastificationItem holder) {
    return Container(
      decoration: BoxDecoration(
        borderRadius: BorderRadius.circular(8),
        color: Colors.blue,
      ),
      padding: const EdgeInsets.all(16),
      child: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          Text('Custom Toast', style: TextStyle(color: Colors.white, fontWeight: FontWeight.bold)),
          Text('This is a custom toast message!', style: TextStyle(color: Colors.white)),
          ElevatedButton(
            onPressed: () {
              // Perform an action
            },
            child: Text('Do Something'),
          ),
        ],
      ),
    );
  },
);

This enables you to mold the toast to fit your app’s aesthetic and functionality!

Troubleshooting Tips

• Toast Does Not Appear: Ensure you’ve wrapped your app in the ToastificationWrapper if displaying without context.
• Custom Toast Not Displaying Correctly: Check your builder function for any layout issues.
• Multiple Toasts Overlapping: Make sure you are utilizing the queuing system properly by triggering messages with appropriate timing.

Global Default Configuration

Want to maintain consistency across toast notifications? The ToastificationConfigProvider allows for global configuration:

MaterialApp(
  builder: (context, child) {
    return ToastificationConfigProvider(
      config: ToastificationConfig(
        margin: EdgeInsets.fromLTRB(0, 16, 0, 110),
        alignment: Alignment.center,
      ),
      child: child!,
    );
  },
);

This ensures your app’s toast notifications maintain the same appearance and behavior effortlessly!
