What Is Flutter?

Flutter is Google’s open-source UI software development kit used for creating applications for Andoid, iOS, Linux, Mac, Windows and Google Fuchsia. What makes Flutter so special is that you can create applications on almost any platform with a single code base. The Flutter engine is written primarily in C++ and is a portable runtime for hosting Flutter applications.

Pros of using Flutter:

The main benefit of Flutter is that you can prototype and develop applications on almost any platform a lot faster while using less code.

The major components of Flutter:

• Dart platform
• Flutter engine
• Foundation library
• Design-specific widgets

Flutters “Hello World” example

import 'package:flutter/material.dart';

void main() => runApp(HelloWorldApp());

class HelloWorldApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {

    //MaterialApp acts as a wrapper to the app and 
    //provides many features like title, home, theme etc   
    return MaterialApp(
      title: 'Hello World App',

      //Scaffold acts as a binder that binds the appBar,
      //bottom nav bar and other UI components at their places     
      home: Scaffold(

        //AppBar() widget automatically creates a material app bar
        appBar: AppBar(
          title: Text('Hello World App'),
        ),

        //Center widget aligns the child in center
        body: Center(
          child: Text('Hello World'),
        ),
      ),
    );
  }
}

Ever wonder which products invade your privacy the most?

Or which internet connected household product is always listening when you don’t think they are?

Well thanks to privacy focused browser Mozilla, now you can get an idea which internet connected products are spying on you the most. The Mozilla foundation have recently launched their fourth edition of  *privacy not included just in time for the holiday shopping season.

We hope you use and enjoy this guide to help you think about, shop for, and buy products from companies that show they value privacy and security. We as consumers need to demand that value from the people who build our products. It’s how we’ll start to make the internet, and our lives, a bit safer in this digital world. That is our goal every day here at Mozilla.

Thank you!
The Team at Mozilla

In a world where pretty much everything you buy is connecting to the internet 24/7, its nice to know what kind of security is built into the products you’re buying for yourself, friends and family. We did some browsing ourself and it’s actually quite scary how many large brands don’t take their customers privacy into consideration.

In a world that is consistently becoming more and more connected, scammers and criminals are constantly looking for their next targets. Being aware of what you’re buying is more and more important for the safety of you and your loved ones.

Was there anything on the list that you owned and were surprised to find out that it was invading your privacy? [wpdiscuz-feedback id=”iibr0wokx2″ question=”Please leave a feedback on this” opened=”0″]Let us know![/wpdiscuz-feedback]
