Flutter Vs Ionic: Top Framework for Cross-platform App Development

In today’s world human beings are more reliant on mobile applications for daily bases task to make living easy and delightful. Smartphones and handy devices for Android and iOS come to the market every month with upgraded features.

To increase the reach of the application to the people it is necessary that your application would be compatible with all types of devices and to do that we need to either create a native application for Android and iOS or we can create a cross-platform application that will be compatible to android and iOS both.

For the cross-platform application ionic and flutter are the 2 names that are in demand nowadays. Every platform has its pros and cons.

Some features that make the flutter a more reliable and adaptive framework for cross-platform applications.


Flutter and Ionic both are open-source software development kits used for developing hybrid mobile applications. But if you go with the ionic then you have to be sound in JavaScript, CSS, and HTML 5 however if you choose the flutter it uses the Dart language which is meant for the server as well as the browser developed by Google.

In simple words, we can say if anyone has some basic knowledge of Android and iOS

then they can easily work on the flutter it does not require any sound knowledge of language.

Dart has some unique features like functions can be put at top-level, outside of any class in Dart.

Classes in Dart have internal interfaces. No external interface makes the language less complex.

Dart tries to minimize the compilation error until it can. The warnings appear in dart but warnings do not interrupt the execution of the program.

Fast App Development

Flutter’s hot reload feature does the quick and easy experiment, build UIs, add features, and fix bugs. Hot reload works by injecting updated source code files into the running Dart Virtual Machine (VM).

Whereas in an ionic rich library of front-end building blocks beautiful app development is the best possible thing but fast app development is still a nightmare in the ionic.

Performance is always the main concern for any application. As we can say that application’s UI is awesome and features and support and compatibility is also perfect but if application is not performing up to the mark then it ruins all the effort and work done on that application.

60% to 70% of users never experience those applications twice which pains them on performance in the first use.

It directly indicates that if your application has performance issues then you already lost 60% of user reach in the start of your application launch.

On the other hand Flutter application performance in most cases will be indistinguishable from the native app and even better in complex UI animation scenarios.

Contrary to the approach of most cross-platform frameworks, Flutter doesn’t rely on any intermediate code representations or interpretation. Flutter application is built directly into the machine code, which eliminates any performance bugs of the interpretation process. Ultimately, you get your release application fully compiled ahead of time with Flutter.


Ionic based OS apps load in web views so the speed of the web views performance is limited.

Animations run slower due to web view performance but even without that it takes a

Collaborative effort to try to make them appear less messy but still not fully eliminate that.

Whereas in Flutter apps compile mode/Debug mode and builds use a Dart virtual machine to run Dart code in order to enable stateful hot reload. And because of Dart VM the speed of the code is fast.


Animations are the most important and interacting part of the application. Animations let users glued with the application and create an willingness to use the application again and again.

Flutter allows you to customize the animations which will be displayed on the front end. Flutter allows you to implement Shared element transitions, shape/color/shadow manipulations, clipping, transformations actions as easy as pie.

Flutter has the library for animation only.So we can say here for animation Flutter is simply great.

Ionic does not have a separate library for the animations and application run in webview so the animations took too much time to run.

Adaptation Risk

In this growing world every technology gets updated in some period of time and both flutter and ionic are not too old in the IT industry.

Flutter has its own rewritten libraries which makes it more reliable and safe instead of the ionic which has kept changing support, standards, and libraries which can be completely rewritten at any time.

No Java SDK integration

In the flutter there is no need to integrate the java SDK for the JavaScript which is the most painful task in the ionic. Flutter uses the dart language for programming and it has its own SDK.

In Spite of the above advantages of flutter some other benefits of using the flutter are:

– Documentation in flutter is comprehensive, well-structured, clean and clear.

– It has a wide range of widgets. From buttons to padding, where every object is a widget.

– It is compatible with other programming languages, and creates eye-catchy and attractive UI in Flutter.

– Flutter is portable i.e. it can run on any device despite varying screen sizes

– Perfect to build a minimal viable product (MVP) and gives access to native features with Hot Reload Feature allows you to check the updates instantly.

– Flutter has Beautiful Pre-Built Components. Whereas Beauty is subjective but there are certain factors that hold across many individuals subjective experiences. Although Ionic has prebuilt Material and Apple components, Flutter has nailed implementation.

Let’s see here Comparison Table between Flutter vs Ionic. We are summarized basic features in this table.


Flutter Ionic
Languages Dart HTML, CSS, JavaScript
Use with React, Vue or Angular
Nature of Apps Cross Platform Hybrid cross-platform
UI Elements Proprietary Widgets Standards-based Web Components
Developed By Google & Community Drifty Co.
Supported Platforms Android, iOS, Google Fuchsia iOS, Android & Web
Open Source Yes Yes, Paid also
Mobile Performance Excellent Very Good
Web Performance Poor Excellent
Deployment Options Mobile, Desktop, Web Mobile, Desktop, Web, PWA


As we have explained the basic need of any application from the end users perspective and flutter is reaching all the standard of those needs.

An application implemented in any platform but if the application gives the high performance,  high speed, Interactive UI, No risk from the new updates and painless SDK integration then flutter is the ultimate responsible framework for this.

Because in the end success is directly related to the end users experience with the application. Flutter will be the grate choice to let the user experience the high quality application.
