In the ever-evolving world of app development, providing users with instant feedback through notifications is crucial for a pleasant user experience. The Overlay Support library simplifies the creation of toast messages and in-app notifications for all platforms. This article will walk you through the steps to implement this library in your Flutter project.

Step 1: Add Dependencies

To get started, you first need to add the Overlay Support library to your project’s pubspec.yaml file. Here’s how you do that:

dependencies:
    overlay_support: latest_version

Make sure to replace latest_version with the most recent version found here. If your project hasn’t migrated to null safety, use version overlay_support: 1.0.5-hotfix1.

Step 2: Wrap Your App Widget

The next step is to wrap your main App widget with the OverlaySupport.global widget. This step allows your app to utilize the overlay functionalities.

import 'package:overlay_support/overlay_support.dart';

@override
Widget build(BuildContext context) {
  return OverlaySupport.global(child: MaterialApp());
}

Step 3: Show Toasts or Notifications

Now, you can easily display toast messages or simple notifications in your app. Here’s how you can do it:

import 'package:overlay_support/overlay_support.dart';

void onClick() {
  // Popup a toast
  toast("Hello world!");
  
  // Show a notification at the top of the screen
  showSimpleNotification(
    Text("This is a message from simple notification"),
    background: Colors.green,
  );
}
