What is Flutter and Why You Should Learn it in 2022

What is Flutter?

Flutter is an open-source newest mobile UI framework by Google. Flutter was introduced by Google in 2017. Flutter allows developers to create cross-platform apps by only using a single codebase and programming language.


Flutter consist of two parts:

The SDK (Software Development Kit): SDK is the collection of tools, which help us to build our applications.  These tools compile our code to native machine code (Code for Android or IOS).

A Flutter Framework: Flutter framework means widgets-based UI Library. This library is the collection of different reusable components (Buttons, Sliders, Text fields, etc.). This framework helps us to create beautiful user interfaces easily.


Programming Language used in Flutter:

To develop the application in flutter we use a programming language called Dart. Dart is a typed object programming language created by Google in 2011. Syntax of Dart is similar to JavaScript and the focus of Dart programming language is on front-end development.

Flutter has many advantages but also has some disadvantages, which we will discuss later in this article.


Why is Flutter Used?

Although flutter is a newer cross-platform framework, many companies use flutter. Developers are switching from other cross-platform frameworks to Flutter. Some reasons “Why developers are switching from other frameworks to Flutter” are:


Advantages of Flutter Framework:

Increase Productivity:

We can increase productivity by using flutter. We can create applications for Android as well as for IOS with one Codebase. With a flutter, we can save Time, Money, and other resources.

Easy To Learn:

Flutter is very easy to learn. Flutter uses 'widgets' which makes the UI easy to use. All features that we can use in an app are provided in the form of widgets by flutter.

Excellent Performance:

Flutter is very fast and efficient. Flutter’s applications performance is nearly equal to the performance of native applications.


Flutter is cost-effective. If we create a native app for Android and IOS separately. It will cost more, but if we create the app using flutter with one codebase it will be very cost-effective.

Great Documentation:

Flutter’s documentation is excellent. We can create a beautiful app with the help of documentation.



Disadvantages of Flutter:

Flutter has many benefits but with benefits, it also has some drawbacks:

Lack of third party Libraries:

Flutter is a new framework so it has limited third-party libraries. Third-party libraries are very helpful for fast application development.

Large Application Size:

As we know, Application’s size is most important to every user. We prefer to download small size applications with the same functionality as large size apps from the play store or apple store. The size of the simple “Hello World” flutter app is about 4MB to 7MB. The same app can be created with native Java will be closer to 500KB to 1MB.

Dart Popularity:

Dart programming is new so it is not very popular. Dart is a great programming language but programmers are often much more likely to consider Java or Kotlin.

Conclusion: In this article, we have discussed what flutter is. Why we should learn and use flutter? Then we have seen some advantages and disadvantages of Flutter. If you want to learn flutter, it will be the best choice to build cross-platform applications. Flutter is efficient and cost-effective. Thanks for reading this article. Keep reading our Blog.
