Calling Native Android Code from Flutter (Step-by-Step for Beginners) When you need to run platform-specific features (like background services, Bluetooth, or sensors) that Flutter doesn’t handle out of the box, you can use MethodChannels to talk to native Android or iOS code. In this tutorial, we’ll: Create a MethodChannel in Flutter. Set up a foreground service in Android. Trigger that service from Flutter—even when the app is closed. 1. What Is a MethodChannel? Think of a MethodChannel as a telephone line between Flutter (Dart) and the platform’s native code (Java/Kotlin for Android, Swift/Objective-C for iOS). Flutter side: “📞 Hey Android, please start the service!” Android side: “✅ Got it, I’m starting it now.” 2. Create the Channel in Flutter Create a new file: lib/native_service.dart import 'package:flutter/services.dart' ; class NativeService {   // ✅ A generic channel name you can reuse in any project   static const _channel = MethodChanne...

What best practices should I follow when creating an API or project to ensure it is secure, not vulnerable to hacking, and protected against ransomware attacks? ChatGPT said: Reasoned about API and project security for a couple of seconds Securing an API or any software project is a multilayered effort that involves designing with security in mind from the very start, continuously monitoring vulnerabilities, and applying best practices both in development and operations. Below is a comprehensive guide covering key areas and strategies that you should consider to reduce the risk of hacking, ransomware attacks, and other security breaches. 1. Secure Architecture & Design Threat Modeling : Perform threat modeling during the design phase. Identify potential entry points, attack vectors, and the impact of a breach. This helps you prioritize security measures based on risk. Defense in Depth : Build multiple layers of security (network, application, data, endpoint). If one layer...
