Which is best: LeetCode vs HackerEarth ?

  Well, all the platforms almost are same except the interface. That's what I think. To conclude the result, let's compare them through the features they offer.  Features of Leetcode -  Topic - wise questions Comapny-wise questions Weekly contests Interview Preparation section Discuss section Features of HackerEarth Topic-wise problems Monthly contests Discuss section Hiring Contests Hackathons Earlier, when I started coding in my first year. I was fond of HackerEarth. But when I stoped using hackerearth and shifted to Leetcode, I like it more. It depends upon how much comfortable you are with the interface. But, it can't be denied that Leetcode offer more than HackerEarth. But for the coders who love hackathons, HackerEarth is best for them and for the people looking out for job opportunities. Do share your favorite through comments!

Pokemon App in Flutter using Pokemon API

In this Article, we will we building a pokemon app using pokemon api. I hope you have Flutter installed and somewhat familiar with Flutter and APIs. Calling APIs for the data and then displaying that extracted data as a beautiful UI is my favorite task. Let's have a look what we will be building today -  1. Add "http" dependency in pubspec.yaml 2. Add this code in main.dart -  import 'package:http/http.dart' as http; import 'dart:convert' ; import 'package:flutter/material.dart'; void main () { runApp ( MyApp ()); } class MyApp extends StatelessWidget { @override Widget build ( BuildContext context) { return MaterialApp ( debugShowCheckedModeBanner : false , home : MyHomePage (), ); } } class MyHomePage extends StatefulWidget { @override _MyHomePageState createState () => _MyHomePageState (); } class _MyHomePageState extends State < MyHomePage > { Map pokeData; List pokeLis
