Why choose Flutter over React/Ionic framework for mobile app development?

Oct 21, 2019/Software Development/

Mobile platforms are in the world for years. There are two major platforms for apps to live on. Those two are - iOS and Android. These two platforms are there since 2012. Although, back then they weren’t as good as now they are. However, there are several questions about which platform to choose from. 


This is because there are two different languages if you select either of them, iOS needs Swift and Objective-C as a language to develop the apps, and in terms of Android, you have Java and Kotlin to choose from. However, most of the time, things get complicated when choosing either of these languages. Moreover, you have to learn 2 different languages at a time to make apps for both platforms.


But the web is there for a very long time. And ever since JS got its track, it started coming to several platforms other than the web, i.e desktop ( electron JS) and mobile (React Native and Ionic ). There are other frameworks, e.g - NativeScript, but that is not a part of this article. These technologies have redefined app development since the launch. All the apps programmed using the React Native and Ionic can run on any mobile platform. However, there also comes a major issue. 


In terms of Ionic, the apps run inside a WebView, which is a terrible idea for an app. It uses Cordova and PhoneGap framework together to make an app and make them install on the mobile device.


In terms of React Native, it is a lot better than your Ionic. But there is a catch here as well. To make the app developed in RN, the JS is compiled into machine code using a JS Bridge, which, in general, is a lengthy way of developing an app. 


Also, the dependencies are highly dependent on third-party developers, who make them either as a hobby, as a profession and whatnot. Also, the UI is designed using traditional HTML/CSS as well. 


Thanks to this JS bridge problem, Google, took the matter into their own hands and developed an SDK called Flutter, along with the language called Dart. Now Dart is an entire programming language on its own and it somehow got its inspiration from C language, thus has a statically typed approach. 


How Flutter with Dart better than React/Ionic framework?


This is the main thing to consider here. As of Flutter, everything is a widget here.


For example, In React Native, you need to write a whole lot of code - CSS, HTML, and JS. Until and unless you use some library for the UI like NativeBase which already has these code written for you.


But in the case of Flutter, All you have to do is: 


import “package:flutter/material.dart”;



    child: Column(

    children: (


         //any other widget 



        //any other widget 



         //any other widget 






See, that’s how simple it is. Please note, the Text in blue are the widgets on their own.


And all these are available in the material. dart library imported in the beginning.


And for that what you have to learn? Just Dart, since the logic of the program, all have to be written in Dart as well. 


Also, there is a good thing about Flutter. The Flutter team asks the developers to write code in BLOCK pattern. Also, this will ensure that the app will have less of the spaghetti code when it gets more complex. 


And Flutter just follows one single design pattern - Material design. And there is not much to do there as well. Even, you can create your widgets using the existing widget as well.


What's more, you can ship the single codebase to any of the platforms - whether its Android, iOS, Web or Desktop. However, as of the new update, Flutter Web is still in the development phase, which also includes the Desktop apps as well. 


Also, it is worth noting, that the UI in Flutter runs on Skia Engine which is a complete 2D graphics engine by Google. Thus, ensuring you 60FPS animation throughout the app.


Do note that Flutter also reduces the time to code and develop an app. 


Even many firms are switching to flutter already. These include Alibaba and Tencent. Also, you can check apps by independent developers on this website as well. 


Flutter is now gaining popularity at a faster pace. More and more developers are also switching to this new SDK. At AppSierra, we develop apps on Native, ReactNative, Ionic, and Flutter.


We are dedicated to becoming the biggest iOS app development and Android app development company. 


Flutter is one of the top choices in terms of app development in AppSierra as well. 


When you ask us to develop apps for different platforms, we consider Flutter as the first choice. And if you consider Native, then it's all your choice!
