What is Flutter?

Flutter is a UI SDK (software development kit) developed and open-sourced by Google which is used to build natively compiled cross-platform applications for Android, iOS, windows, etc. For instance, a single codebase in flutter can be used to run the app on both iOS and Android instead of generating a separate codebase. It was first released in May 2017 while its stable version arrived in December.


Why Flutter?

Usability: Flutter uses builds cross-platform apps. by complying single codebase that can create apps for both Android and iOS. It makes use of the programming language ‘Dart’ – created by Google where one doesn’t have to write Android code in Java or Kotlin and iOS code on swift or Objective-c separately. An App Making Company recognizes the potential of any services and engineers particular solutions to meet certain standards. A single codebase written in flutter using dart language can be natively compiled to both iOS and Android. Although, it doesn’t mean it would have limitations to add something platform-specific to the app. Flutter authorizes us to encode to determine the mobile operating systems and can implement separate specific utilization accordingly. Mobile App Development Company like Electrum IT Solutions Pvt. Ltd. has the capability to deliver solid services.

In this article, we would be comparing flutter with the two most popular alternatives of a flutter: React Native and Ionic.


Framework & Compilation to native App: Flutter uses Dart and flutters framework, tada, created by Google which provides likely a good chunk of the native components in the framework itself and so it doesn’t always need a host to communicate with native components. On the other hand, React Native uses JavaScript/React.js. In React Native, one can find some parts of code that are not compiled to native apps rather they are enclosed in native apps and run as JavaScript in the mentioned app. Ionic uses a few or no frameworks as nothing is compiled to a native app. WebView is created and wrapped so we do get a similar outlook but it’s a web app wrapped inside a native app. An advantage of Ionic would be webApp structure as web developers have it at ease to use their web development skills. The more the code is compiled to the native app better the performance. Although, the react native or Ionic would be easier to initiate if familiar with JS however flutter provides a much greater range of UI components and performance when compared.

Platforms: Flutter can build cross-platform apps including mobile, web, and desktop apps. With react, native one could almost build mobile apps to an extent while some support could be used from react native app as a web app. Ionic is a WebView therefore we get a cross-platform app that runs on mobile, web, and desktop apps. Excellent outsourcing Android App Development Company understands the depth of expertise and resources. 

Stability & Future: Flutter is backed by Google, react-native by Facebook, and Ionic backed by Ionic. These companies backing up add more strong foundation and the validity of existence increases to an immense level.

Everything is a widget: In flutter, everything is a widget, whether a button, text field, AppBar, or even your complete app page is a widget built with multiple widgets. Flutter compiles the app to the platform-specific native app using flutter SDK which is then highly optimized native Android or iOS app and provides great performance. The optimization usually is delivered by an Android App Development Company.  However, the compilation of components won’t necessarily be done at all times to native ones. Flutter does not use platform primitives for e.g., if we want to add a button, in flutter it can be done by using the RaisedButton widget which creates and displays a button. You might think that compilation to android or iOS app would get translated to a widget. Button (the default button for android) and UIButton (the default button for iOS). No, it isn’t the case. The Flutter has its own implementations as it controls each pixel on the screen. It ships its own engine which controls every pixel on the screen. As a result, the compilation of the code to the native app is done limitlessly where the UI doesn’t get compromised with native components. This leads us to our next feature. Widgets are really important and an App Making Company deliversuccessful items in the internet space. 

UI as code and the widget-tree: In flutter, we don’t have a visual drag and drop of components to build an app instead we code and build a widget tree. Basically, everything in flutter is a widget as you might be aware of the first feature. So, a complete widget tree is created at the code level and also under the hood when the app runs. This also gives us the advantage of a much better understanding of the code at each level for instance, if we are building an app that has a login page. Build the AppBar at the top and use a column widget to align other widgets vertically such as email and password text fields and a login button in the body. Thus, a widget tree is created that helps to understand how each component or widgets are related to each other instead of just visually drag and drop things to place without paying attention to the structure.

Hot Reload: One of the most loved features among mobile developers. Generally, changing some code in the app and re-rendering it, reloads the entire application and results in more consumption of time. However, the hot reload of flutter creates a virtual widget tree and compares the changes, and only modifies things that are changed without altering the state of the app, resulting in a quick reload.


After considering all the aspects, we come to the final conclusion that although it might be easy to start with react native or Ionic for web devs and other developers who already know JavaScript. As of flutter, its learning curve is quite steep as grasping dart language can be difficult which is an object-oriented language. It gives us great power with performance and amazingly customizable, rich, and beautiful UI with cross-platform support. In the end, Flutter is definitely a great and powerful tool for building apps.
