What is Flutter?

Released in 2015, Flutter is an open-source platform that had an intent to organize a marketplace for Google Fuchsia. This SDK helps to create native-looking apps, web, and desktop utilizing a single codebase.

Flutter is a framework compatible with iOS, Android, Web, and Desktop. Its library offers a single API to define views for multiple platforms at once. 

Following is a sample of a Flutter application:

import ‘package:flutter/material.dart’;void main() => runApp(MyApp());class MyApp extends StatelessWidget {


   Widget build(BuildContext context) {

     return MaterialApp(

       title: ‘Welcome to Flutter’,

       home: Scaffold(

         appBar: AppBar(

           title: Text(‘Welcome to Flutter’),


         body: Center(

           child: Text(‘Hello World’),






Google UI framework focuses on prevailing technological and market challenges. As a result of which Flutter became an ideal cross-platform app development framework within a very short time.

What are the Features of Kotlin?

Here are the features making the language popular:

1. An SDK, not Framework

When you plan to build your app in Kotlin, there is no need to shift the complete app. Developers you hire to start with a single module, decide the working model, and then progressively migrate different components. 

2. Simple Language

Kotlin has its syntax quite similar to the programming languages like Swift, Java, Groovy, and Scala, it is fairly simple to understand the language. 

3. Reuse of the Logic

This is not the only platform that allows separating UI and enterprise logic. Xamarin and React Native are other frameworks that also provide this kind of service. 

There is one thing making I different from others i.e. shared logic and libraries within the UI layer. This makes the Kotlin developers work together in the native surroundings:

  • Swift and XCode for iOS
  • JavaScript for the Internet
  • Kotlin
  • Android Studio

All this is done without utilizing any bridge in an extra native manner.

4. Native UI Expertise

Kotlin Multiplatform doesn’t demand any instructions for creating UI. The Kotlin developers can work on the design, appearance, and efficiency appliance similar to native.

5. Scalability and Flexibility

The developers can scale up the applications without utilizing any virtual machine (VM). This makes it an ideal choice for creating an app where scalability and flexibility are necessary.

What Developers have to say regarding Kotlin Vs. Flutter?

“Dart is just a wannabe amateur hobby me-too project compared to Kotlin.”

Mike Milpot, Software Architect, Inventor

“Apart from the fact that you can still call Android/iOS APIs, building Flutter UIs is a bit more exhaustive than it is on Android.”

Wilberforce Uwadiegwu, Mobile Software Engineer, NCK Tech

“You can, of course, use the Flutter knowledge to develop iOS apps later, so it can be more useful knowledge if you want to focus on mobile app development, but learning java will give you a step if you want to work on Back-end web development.”

Maycon Miranda, Web Developer, Bio Extratus

“Currently flutter lacks a library/guide in comparison to Kotlin/Java. Therefore sometimes you’ll need to transfer or wrap the Android library to flutter by yourself. It’ll make the time of developing your application increased.”

Phạm Anh Minh, Samsung Vietnam Mobile R&D Center
