  • It is based on SAAS and for creating strong & rich applications it provides tons of UI components.
  • Ionic comes transported with a ground-breaking CLI, providing the developers with the capacity to assemble and test Ionic applications on any stage.
  • It provides all the functionality that you can found in native mobile development SDKs.

What is Flutter Framework?

It is an open-source mobile application development framework for creating high-performance, high-fidelity mobile applications for Android & iOS. Flutter apps are written in the Dart language which can be compiled to JavaScript. The major components of Flutter include Dart platform, Flutter engine, Foundation library, and Design-specific widgets. Using this framework, it is easy to build user interfaces that react smoothly in your app as it reduces the amount of code required to synchronize and update your app’s view.

Key Features of Flutter Framework

  • It incorporates a modern react-style framework, instant gadgets, and development tools.

Pros & Cons of Both Ionic and Flutter

It’s important to have a look at the pros and cons of both the contenders of the race, i.e. Ionic and Flutter. So, let’s start with the Ionic followed by Flutter.

Pros of Ionic

  • Free and open-source JS framework.
  • It is easy and simple to learn with built-in components facility.
  • The ionic framework supports iOS, Android, Windows, Web, and PWA.
  • Faster Development life cycle.
  • Framework’s focus on HTML, CSS, and JS enables quick development and low costs.

Cons of Ionic

  • Building in-app navigation can be complex.
  • Performance is not as good as Flutter.
  • The issue additionally lies because of WebView native-like experience.
  • Interactive transitions are a difficult customer to handle.

Pros of Flutter

  • It is hot reload which means that the developers can see all the changes they’ve made to the code.
  • Perfect for an MVP.
  • It improves overall performance as well as app startup time.
  • It gives access to native features.
  • Easily learnable

Cons of Flutter

  • It isn’t supported by web browsers as it only mobile applications.

What should you choose?

There is no awful decision here, as a matter of first importance, you need to choose you want to stick to the native languages (Swift, Objective-C, Java) and accept the disadvantage of learning two things and writing two apps. This is a huge work as mastering two languages is way harder than mastering one. But, in the event that you would prefer not to use the native languages, then you need to choose whether you need a wrapped-application solution as Ionic offers it. Ignoring the performance disadvantage you will get a super-fast development experience. But if performance is super important to you and you need to access a native device features then you should have a look at Flutter as it provides better performance than Ionic.
