In the IT industry, the latest mantra has become - Code Once, Use Everywhere. Nowadays, businesses prefer going with hybrid mobile applications way more than the native competitors. One of the reasons behind this is that hybrid apps cut down the development costs and time to a great extent. 

Having said that, the two most popular hybrid frameworks available out there are Flutter and Ionic. Both of them are equipped with a huge team of developers, consistently working to bring uniqueness. 

While Flutter provides integrated tools, customizations, and an extensive set of inbuilt widgets; Ionic offers a wide range of plugins to speed the development process. So, in this post, let’s dive deeper into Flutter vs Ionic and find more. 

Ionic vs Flutter: Overview

What is Ionic?

An open-source UI toolkit, Ionic allows you to create hybrid cross-platform mobile apps. It makes use of Webview for mobile rather than using native elements of the device. This framework makes the most out of JavaScript codebases, such as Vue, React, Angular, Vanilla JavaScript, and more.

Additionally, Ionic features multiple components that offer native functionality. This framework is known for providing effective performance with minimum DOM manipulation. 

What is Flutter?

This one is an open-source framework that works with Dart - a language developed by Google. Flutter is commonly known as an improved UI toolkit that is used to develop cross-platform applications through a single codebase.

It offers accessibility to develop flexible and expressive UI with native performance. In addition to this, Flutter is contributed and supported by a team of Google developers alongside the flutter community.

Flutter Vs Ionic: Pros and Cons 

Jotted down below are some pros and cons of flutter and ionic that you should know: 

Pros of Flutter

  • The stateful hot reloading feature displays changes instantly without losing the state of the application.
  • Codes can be written and shared across platforms faster and easier, making them ideal for MVP development.
  • It offers rich widgets that follow the guides of Material Design (Android) and Cupertino (iOS).
  • Flutter provides quick iteration cycles and saves the build time as testing is needed only for one codebase.
  • In Flutter, rewriting the code is not required as it gets seamlessly integrated with Objective C or Swift for iOS and Java for Android. 

Cons of Flutter

  • In Flutter, libraries and tools are not rich.
  • It cannot push updates and patches instantly into applications without passing them through the standard processes of release.
  • Animation and vector graphics support have rendering plugins issues on time.
  • It is not compatible with the development of apps for watchOS, CarPlay, Android Auto, and tvOS. 

Pros of Ionic

  • The platform-independent framework decreases the effort, time, and resources employed to develop cross-platform apps while providing them with a native feel and look.
  • Ionic scales effectively as the number of active users does not affect the performance.
  • It saves build type by offering a simplistic interface for accessing native API and native SDK on every platform.
  • It creates a single codebase with the help of familiar Javascript libraries and frameworks; thus, decreasing code rewriting. 

Cons of Ionic

  • Developers need to come up with highly-specific features in plugins.
  • It is not ideal for complex or memory-intensive applications as it uses WebView to render applications. Using Ionic to develop heavy apps will make them crawl.
  • It ends up refreshing the entire app whenever you have to make changes; thus, impacting the speed of development.
  • It uses older versions and doesn’t offer code uglification.

Flutter vs Ionic: Performance Comparison

How does Flutter stand out?

Comparably, Flutter offers better performance than the arch-rivals. It doesn’t need a bridge to communicate between native modules because of the native components’ default availability. If the performance test is to be believed, it has been indicated that the “hello world” app performed at 60 FPS always and the time is taken for rendering each frame didn’t go beyond 16 milliseconds.

The number of dropped frames was fewer as well. Flutter makes use of the Skia graphics library, allowing the user interface to be redrawn every time with every change done in the application view. This is how Flutter performs effectively at 60 FPS. 

How does Ionic stand out?

Ionic is one of the best cross-platform frameworks. It was only recently, in 2019, when it rose to its popularity. The apps developed on the Ionic framework have experienced a rise of 53.3% since January 2019.

As far as the performance is concerned, the Ionic apps provide 60 FPS on both desktop and mobile. They use pre-existing plugins and provide a hybrid methodology to speed the development process. The interactive time of the framework is fewer than 1.8 seconds. Although its framework is non-native, Ionic still excels in offering hardware accelerated transitions, pre-rendering and touch-optimized gestures. 

Flutter vs Ionic: Application Architecture

Selecting the right architectural framework can simplify the entire process of development and will help your application by offering support during future updates. 

What kind of architecture does Flutter support?

The architecture of Flutter is layered. The hierarchy of a basic application developed on this framework begins with the top-level root function, which is also known as platform-specific widgets. It the then followed by simple widgets that are meant to interact with the rendering and platform layers. 

Beyond the rendering layer, you will find animation gestures that are meant to transfer API calls to the application’s foundation. It is also called Scaffold that is operated by a C or C++ engine along with a platform-specific embedder. 

If you wish to separate the business logic and the presentation layer, you can implement Flutter BLoC. This architecture turns out to be seamless for both junior as well as experienced Flutter developers when it comes to developing complicated apps with simple and small components. 

What kind of architecture does Ionic support?

Ionic makes use of AngularJS MVC architecture, which is a software design pattern that consists of a Model View Controller to develop sophisticated cross-platform, single-page apps optimized for mobiles. This architecture allows multiple developers to work simultaneously, which decreases the turnaround time and increases productivity.

Furthermore, since the architecture enables the development of multiple Views, the application is immune to recurring iterations. 

Code Maintainability – Flutter vs Ionic

When it comes to code maintainability, Flutter is much easier to maintain in comparison to Ionic. Let’s find out more here: 

How convenient is it to maintain code in Flutter apps? 

Maintaining a Flutter application is extremely easy. The code’s simplicity assists developers in spotting issues, sourcing external tools, and supporting third-party libraries. Moreover, the Hot Reloading feature instantly resolves the problems at hand. 

The time consumes to release qualitative updates and make instant changes in the apps is much better than Ionic. 

How convenient is it to maintain code in Ionic apps? 

With Ionic, often developers have to rewrite the codes to maintain stability in the application; thereby making code maintenance a challenging issue. On top of that, the backward compatibility breaks a lot of time, making it, even more, worse and a frustrating experience.

Suitability for building complex apps– Flutter vs Ionic

In the present era, both of these frameworks have several official guidelines, documents, third-party libraries, plugins, and open-sourced projects to support developers throughout the process. However, upon comparing Ionic and Flutter for feasibility, the latter is preferable to develop complicated apps 

Is Flutter suitable for building complex apps? 

Often, developers get attracted toward frameworks that take less effort to integrate during the lifecycle of development. Flutter is available with a plug-in system that assists apps in communicating with the operating system for such functions that are non-UI. 

While iOS experts use Cupertino Widgets to develop interfaces, Android developers use Material Components to add value to their apps. With Flutter, all you would need is to create such a team that has experience in Dart or is willing to learn it. 

Is Ionic suitable for building complex apps? 

The recent version of Ionic - v5 - is not ideal for developing complicated applications. Whenever you would try to add complex functionalities to the app, you may face challenges with certain features, such as animated UI, image processing, location-based services, etc. 

However, Ionic is definitely an optimal solution for developing simple, small-sized applications. 

Comparing user experience – Flutter vs Ionic

Flutter’s Ability to Give the Best User Experience

Flutter provides a rich user experience with simple elements, tools, and customized widgets. Once you have understood everything about AnimationBuilder, StreamBuilder, and FutureBuilder, there will be no restrictions on how you can customize the user interface. 

The feature of generational garbage collection is a part of Dart as well that assists you in developing UI frames for object codes that could be temporary. This Dart feature allocates objects in a single pointer bump that neglects UI junk, clutter as well as animation shutter lag during the process of development. 

Ionic’s ability to give the best user experience  

Ionic provides a seamless, rich in-app experience for both Android and iOS applications to create a transient UI navigation and native-like persistence. The hybrid methodology eradicates the need to submit a newer version to the app stores.

This lets you rapidly develop features within the native mobile app container that send live updates to the devices of users. On top of that, users don’t need to download the app apk frequently to get new updates.

Testing – Flutter vs Ionic

Maintaining the smooth and intuitive functionality of a code with minimal effort and time is one of the primary objectives of development. Let’s have a glance at varying methods and tools that both the frameworks provide to make sure testing quality is retained: 

Testing possibilities in Flutter   

Considering that Flutter operates with Dart, it offers extensive support for automated testing. If, as a developer, you have used Spec, Spek or Mocha, unit testing in Flutter will be a child’s play with a ready-to-use unit test framework. 

A library, such as Flutter Test, offers the required tools for widget testing. Furthermore, several tools, such as XCUITest and Appium can be used to simulate UI testing. And then Dart packages, such as Flutter driver, provide an instrumental testing suite for integrated testing and widgets. 

Testing possibilities in Ionic

Testing an Ionic app is comparatively simple and is developed with web-based technologies. You will not require additional emulators or testing devices as the app is already tried and tested in varying browsers through WebView.

Browsers offer inbuilt debugging and testing tools to make the entire process of testing convenient. Moreover, Ionic CLI has all of the functionalities for testing the web component. 

Flutter vs Ionic – Application size

Evaluating APK files as well as codes will make sure that the components and libraries used don’t impact the application’s size. To explain it thoroughly, let’s consider the “Hello World” app. 

Size of the application in Flutter

The hello world app’s size in Flutter was 7.5MB. With this framework, the app’s size got influenced by the C/C++ engine and the Virtual Machine of Dart. But, Flutter is capable of self-containing all of the assets and codes to neglect the concerns related to the size.

Moreover, using a special tag, such as split-debug-info, can help decrease the code size to a great extent. 

Size of the application in Ionic

With the introduction of Ionic v5, the size of the hello world app that was developed in Ionic is decreased to 3.2MB from 5 and 6MBs that were there in the previous versions. Also, the use of special tags during the process of development - prod - release has further decreased the ap size. 

Flutter vs Ionic – Learning Curve

Is flutter easy to learn?

Flutter is not difficult to learn. Writing down a code with Dart could be quite unusual, however, that is what makes it easier to develop with Flutter. If you wish to learn this framework, you will have to be familiar with the basic know-how of native iOS or Android development. Moreover, considering that documentation in Flutter is much smoother, you will easily get to learn everything about it. 

Is Ionic easy to learn? 

Ionic could be seamless for developers who have significant hands-on experience with Angular. All you would need is to explore the framework, specifically CLI or Cordova plug-ins. In addition to this, JavaScript coders who have experience in styling applications with CSS/HTML have a head start on learning Ionic. 

Hiring developers – Flutter vs Ionic

Regardless of the benefits and drawbacks of Flutter and Ionic, it is essential to be familiar with the cost you would have to pay to hire experience developers before you begin the development. 

How convenient is it to hire Flutter developers?

If you wish to hire a flutter developer, the average cost comes anywhere between $20 to $100 an hour. The big players out there, such as Alibaba, Watermania, BMW, and more had to hire a minimum of 5 developers to build the applications on Flutter. 

How convenient is it to hire Ionic developers?

If you are looking forward to hiring an Ionic developer, you will have to pay anywhere between $10 to $150 an hour, based on their years of experience and skill set. However, if your app has a complicated structure, it is recommended that you go with a dedicated team rather than hiring individual developers. 

Best Choice - Flutter vs Ionic

Choose Flutter, if: 

  • Your ideas don’t need complete native functionality
  • You want to customize UI with the help of widgets and less testing
  • Your budget and delivery timeline are tight
  • You know the basics of Dart
  • You wish to write and deploy codes faster 

Choose Ionic, if:

  • The application idea is new and you want to launch a startup
  • You know web-based technologies
  • You have a tight budget and wish to keep the expenses as minimum as possible
  • The application is simple and doesn’t need high-end customizations

Conclusion

Both of these frameworks are adequate for developing hybrid applications. However, the preference depends and varies from one individual to another. If you are still confused, make sure you go through the case studies of both Flutter and Ionic and zero down upon your requirements. And then, you can choose one accordingly.
