Introduction to Flutter and React Native

What is Flutter? Who created Flutter?

A Flutter is a development framework/Kit, which is created by Google and it’s team. By using flutter as a development kit you can develop applications for Android, iOS and Web that too from a single codebase (Code once and build installation setup for various platform)

Hello, World program in Flutter looks like this:

import 'package:flutter/material.dart';

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

class HelloWorldApp extends StatelessWidget {
  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'),

What is React Native? Who created Flutter?

React Native is one for the famous framework used to develop applications for Android, iOS, web and more, React Native helps developer to use react along with native platform capabilities.

React Native also allows developers to write native code in languages such as Java for Android and Objective-C or Swift for iOS which make it even more flexible.

Hello, World program in React Native looks like this:

import React, { Component } from 'react';
import { Text, View } from 'react-native';
