Custom AndroidTV Notification

A Flutter package that provides a simple way to display overlay notifications on top of your app, even when it's in the background.

Features

• Show overlay notifications on top of any app
• Hide notifications programmatically
• Permission handling for overlay display
• Works in both foreground and background

Getting Started

Add this to your package's pubspec.yaml file:

dependencies:
  notification_overlay: ^1.0.0

Usage

import 'package:notification_overlay/notification_overlay.dart'

Check and Request Permission

Before showing notifications, check and request overlay permission:

bool hasPermission = await NotificationOverlay.checkOverlayPermission();

// Request permission if needed
if (!hasPermission) {
  bool granted = await NotificationOverlay.requestOverlayPermission();
}

Show and Hide Notifications

// Show a notification
await NotificationOverlay.showNotification('Hello World!');

// Hide the notification
await NotificationOverlay.hideNotification();

Complete Example

import 'package:flutter/material.dart';
import 'package:notification_overlay/notification_overlay.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Notification Overlay Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              ElevatedButton(
                onPressed: () {
                  NotificationOverlay.showNotification('This is a test notification');
                },
                child: Text('Show Notification'),
              ),
              SizedBox(height: 20),
              ElevatedButton(
                onPressed: () {
                  NotificationOverlay.hideNotification();
                },
